The cartridge spray gun can also be used to inject urethanes into cavities for filling or floatation applications.

To begin spraying, only an air compressor, a cartridge spray gun and a loaded cartridge set are required.  For customers who wish to spray large volumes of material this may not be the most economical spray method. The one time use disposable plastic cartridges significantly increases your cost.  In addition to the cost of the disposable cartridges, there is a significant amount of plastic waste generated because a fully loaded cartridge only contains 1.5 liters of coating (.396 US gallons), it takes 2.5 cartridges to spray one US gallon of coating. The cartridges are not designed to be reloaded or reused.  The cost of disposable cartridges and mixing tips can increase the cost of coating application more than $25.00 USD per gallon, but in many cases this extra cost is well worth the low maintenance and convenience provided by the cartridge spray gun.

We manufacture a variety of coatings and foams which can be spray applied using the cartridge spray gun. Customers hand fill spray cartridges as needed.  The video window located on this page demonstrates the filling procedure for spray cartridges. Cartridges are simple to load by hand pouring, no special loading equipment is required.  We recommend that cartridges be loaded for spraying within a few days of use because pigments, blowing agents and other ingredients in the urethanes quickly separate when allowed to sit in a closed cartridge.  Once materials are loaded into a cartridge it is impossible to stir them up, and shaking a cartridge does not adequately mix it. For best results, load cartridges as  needed and store at proper temperature between 70 to 85F before use.

Our StyroSpray product was used in the construction of a light weight formula car body constructed from expanded polystyrene. Styrospray provides an impact resistant surface over low cost EPS foam which is very easy to cut and shape with simple hand tools , hot knife or hot wire. Our product allowed the team to quickly shape the light weight car body from low density EPS foam. The Styrospray

Product eliminated the need for expensive and time consuming fiberglass layup and molding. The ability to free form a light weight durable car body from low density foam paid benefits not only in the fuel efficiency challenges but also in the electric only acceleration trials. This superior engineering method also proved itself on the track through rigorous mechanical inspections.

Judges and guests were impressed with the car’s innovative parallel hybrid architecture.

It affords an elegant approach to allowing electric only power without spinning the motor while still allowing a combination of electric and gasoline power. We at Industrial Polymers are proud to support students in their journey to becoming world-class engineers in the green transportation sector. UC Davis Formula Hybrid Business Division has already started on FH3 as they begin reengineering parts and recruiting new members.

A larger than life mosaic side profile of two faces made from mirror pieces. Several local businesses were happy to find a use for their reject mirrors that would have normally been waste but instead (were) used in this piece. The faces are modeled from photographs I took of two friends. The best part of ArtPrize last year was seeing all the people in downtown Grand Rapids. This mosaic is meant to reflect that.The large greeting card in the back is not part of Mr. Blough’s work.

Thank you for all your help! StyroSpray 1000 has worked out incredibly for me and has blown me away with it’s finish and durability. I also took your advice on using the black pigment for gray and it looked great. I really appreciate the product and have since referred it to friends in the Chicago area who have come to love it as well.

Here is the finished product,

TrueKote CS-200 is frequently used in industrial maintenance where a slip resistant texture surface is required.  This coating has been used successfully with a urethane base primer on aircraft, railroad cars, ships, storage tanks, metal bridges, roadways, piping, structural steel, concrete, wood and some plastics, including vinyl. TrueKote CS 200 is preferred over epoxy type nonskid coatings in applications where substrate surface experiences frequent traffic or impact, movement and or vibration.  The flexibility of CS-200 is inherent in the basic urethane polymer and not achieved by the use of fillers or plasticizers.  This enables the TrueKote CS-200 coating to remain flexible over an extended service life or on structures which experience movement or vibration.

TrueKote CS 200 is packaged in pre measured one gallon or 5 gallon kit containers. It contains sand and aluminum oxide particles to achieve an aggressive non-slip surface profile.  To use this product a part A and part B component must be mixed together at time of use. Coating must be applied to substrate immediately after combining part A and B components. TrueKote CS-200 becomes tack free in 2 hours and dries hard in 12 hours @ 77 F and 50% Relative Humidity conditions.  Coating is suitable for normal traffic use in 48 to 72 hours. At cool or cold temperatures (below 60 F) additional curing time will be required before full service properties are achieved. The standard color of TrueKote CS-200 is Standard Safety Yellow.  A range of color options are available, call or email us for current pricing and availability.

Expansion joint sealant product used in airport runway operations or applications where a fuel resistant sealant/coating is required. Primer 200 is applied directly to clean concrete surface by brush or roller, wait 1 hour before application of UraSeal 210 into concrete crack or expansion joint. UraSeal 210 can be poured into concrete expansion joint after surfaces are primed and prepared.  See coatings and sealants product page for more information on UraSeal 210 product. Primer 200 contains VOC solvents and is classified as flammable material.

Primer 450 is a two component urethane primer used to increase adhesion of urethanes to painted metal surfaces, wood, (some plastic surfaces) or concrete. Primer 450 is required when installing our Speedliner 1000 spray on truck bed liner product into cargo bed area of light duty trucks or other painted metal surfaces.  Primer 450 is also used as a bonding agent between new and old urethane coatings. It is applied by spraying, brushing or roller application. For best results, surface should be cleaned, abraded and wiped with solvent prior to Primer 450 application. When recoating spray-on truck bed liners, Primer 450 must be used to bond new truck bed liner coating over existing spray-on truck bed liners. Cure time depends on temperature and relative humidity, Mix ratio 1:1 by volume, brush, roller or spray-on application.  See Speedliner product page for complete information on our spray-on truck bed liner products. Primer 450 contains VOC solvents and is classified as flammable material, see material safety information.

Primer 460 is a two-component primer used to increase the adhesion of urethane coatings to fiberglass or aluminum surfaces. Cure time depends on temperature and relative humidity, Mix ratio 1:1 by volume, brush, roller or spray-on application. A surface preparation wash of Turco Alumiprep 33 from Henkel Corporation must be used when priming over aluminum surfaces. The application procedure for aluminum surfaces: clean and abrade or blast aluminum surface, solvent wipe, apply Turco Alumiprep 33 preparation wash, rinse with water (do not allow preparation wash to dry on surface before rinsing off).  The application procedure for fiberglass surfaces: clean and abrade fiberglass surface, solvent wipe, apply Primer 460.  Primer 460 contains VOC solvents and is classified as flammable material, see material safety information.

Primer 700 is a two-component urethane primer designed for use on concrete, wood and other porous substrates in coating applications where a solvent based primer cannot be used.  Primer 700 is formulated to be used with fast cure (1 to 3 minute cure) plural application coatings over concrete; these are coatings which are spray applied through high pressure plural mixing/spraying equipment or the dual cartridge with static mixer type spray guns.  A solvent free primer must be used with very fast curing coatings to prevent bubbling as solvents evaporate from surface.  This primer should be allowed to full cure overnight before spray application of fast set coatings over it.  Use this primer over concrete surfaces when spraying Speedliner 500, 600 and 700 series coatings. It also exhibits a low sensitivity to substrate moisture, leaving minimal bubbling when applied to damp surfaces. Mix 1:1 ratio by volume, brush, roller or spray-on application. Primer 700 contains no VOC solvents and is classified as non-flammable material, see material safety information.  Primer 700 should not be used with our Speedliner 1000 spray-on truck bed liner product.

A disadvantage of using the hand held cartridge spray gun is the added cost of the disposable plastic cartridges which only hold 1.5 liters of product and cannot be reused. The cost of the disposable plastic cartridges and mixer tips is approximately $8.25 per cartridge set and it takes approximately 4 complete cartridge sets to spray only one gallon of InstaGel Spray rubber. The cost of disposable plastic cartridges adds $33.00 per gallon to the cost of spraying your rubber. If you plan to use large amounts of spray on mold making rubber the more expensive electric spraying equipment may be a good investment over the long run and reduces landfill waste. The electric spraying equipment should be purchased directly from an equipment manufacture/supplier who can offer long term maintenance, technical support and training. We routinely direct customers to Spray-Quip Incorporated at 800-500-9109 www.sprayquip.com or Michael Engineering at 989-772-4073 www.michaelengineering.com for price quotes and help in selecting the spraying equipment which best serves your needs.

InstaGel Spray is urethane which becomes very thick after the part A and B components are mixed together. Having a urethane product which is very high in viscosity (a paste consistency) allows the product to be applied very thick on a surface without sagging or running down. Spray on rubber mold making rubbers are very help and time saving when you are making rubber molds from large 3 dimensional masters. A spray on rubber is also helpful if you want to spray into an open faced mold to make a large flexible rubber skin for animatronics applications. If you would like to make a rigid plastic shell instead of a flexible rubber skin we manufacture UraGel 760 which cures to become a hard surface. UraGel 760 is sometimes used in open faced silicone rubber molds to make large masks or reproduction suits of ancient amour. UraGel 760 can be sprayed into a silicone rubber mold ¼ of an inch thick or more to make high durability rigid plastic parts. Customers frequently use UraGel 760 over InstaGel Spray to create a hard supporting mother mold for their brush on rubber mold. The InstaGel Spray and UraGel 760 products are available in 5 gallon plastic pails and 50 gallon drum quantities. Please call 800-766-3832 / 713-943-8451 or email us for current pricing and delivery options.

We manufacture 3 spray-on gel products for making flexible rubber molds and 1 spray-on gel product (UraGel 760) which cure to be hard plastic. Instagel Spray 20 is the softest and Instagel Spray 40 is the hardest flexible spray applied rubber product we manufacture. The cured hardness of InstaGel Spray rubbers increase from 20 Shore A to 65 Shore A, see chart below.

InstaGel Spray 20 flexible (25 shore A) Good for making molds with deep under cuts

InstaGel Spray 30 flexible (30 shore A) Spray-on mold making flexible rubber

InstaGel Spray 40 flexible (40 shore A) Spray-on mold making flexible rubber

InstaGel Spray 65 flexible (65 shore A) Frequently used as a top coating for flexible foam construction.

UraGel 760 Hard (75 Shore D) rigid Spray-on mold back-up material or for making rigid parts in mold

Our spray-on gel products can only be sprayed by disposable cartridge or low pressure electric gear pump type plural spraying equipment. If you are pumping out of 5 gallon containers or drums it is important that the Part B storage container be thoroughly mixed each day before use. The part B component of InstaGel Spray settles out quickly in storage container and must be thoroughly mixed to insure InstaGel Spray cures properly when applied to your master. InstaGel Spray begins to cure in the static mixer spray tip and quickly gels on the surface of your model. InstaGel part A and B components are color coded so you can watch for color variations in the mixed product to see if your spraying/mixing equipment is functioning correctly. Variations in the color of applied InstaGel Spray indicates your equipment is not functioning properly. Product which is not thoroughly mixed will appear off color and weak areas or sticky spots in your mold will result. After mixing equal volumes of A and B components together our gels transform into a creamy paste consistency. You may apply our molding gels up to 1/2- inch thickness in a single application without sagging or running. These products remain in a gel consistency for approximately 10 to 15 minutes after spraying. We recommend you allow 24 hours curing before using the finished mold. Fabric or chopped fiber can be added to enhance physical properties of cured gels both rigid or flexible. Application of the molding gels should be done in a dry environment to prevent surface bubbling. Clean up should be done with solvents such as mineral spirits, Methyl Ethyl Ketone (M.E.K.), or acetone solvents. Both InstaGel Spray and UraGel 760 contain no V.O.C. solvents and are nonflammable, low odor products and classified as nonhazardous for shipping purposes. See material safety information for complete information.

InstaGel is a flexible, spray-on product for making rubber molds from objects or wall surfaces which cannot be placed in standard box molds (any 3 dimensional objects or vertical wall surface). After mixing, InstaGel Spray thickens to a creamy spread-able gel which can be applied onto vertical or overhead surfaces without sagging, or running. Within 24-hours InstaGel Spray cures to a tough rubber mold. Before applying InstaGel Spray, surfaces should be coated with silicone or wax mold release and must be free of moisture to prevent unwanted bonding or surface bubbling. Mold releasing agents must be used to insure easy removal of InstaGel Spray rubber mold from the master.

UraGel 760 is a rigid (75 shore D) Spray-on mother mold making material or low odor fiberglass replacement product. UraGel 760 is also used for manufacturing in-mold hard parts, reproduction ancient amour and decorative masks. Use this product any time you need to make hard durable parts from a large open faced mold.

UraGel 760™ is formulated for spraying hard mother back-up molds or hard plastic parts. It can be sprayed into rubber molds 1/2-inch thick in a single application. When fully cured UraGel 760™ forms a rigid “fiberglass like” polymer which is easily sanded or machined and painted to final form. UraGel 760™ is recommended as a rigid Mother Mold back up for flexible InstaGel Spray molds. Polyester fabrics and chopped fibers can be used with these materials to enhance strength and durability. UraGel 760’s thick gel consistency makes it easier to work with than fiberglass, no cloth lay-up required. Very thick sections can be created in a single product application, no flammable fumes or odor.

Procedure for making a brush-on mold from textured or carved wall surface or clay master;

1. Apply appropriate mold releasing agent (silicone spray, furniture paste wax) to surface.

2. Spray apply InstaGel Spray to entire wall area at the desired thickness (1/4″ to 1/2″ thickness). Allow to cure overnight before beginning step 3.

3. Apply appropriate mold releasing agent over the InstaGel Spray (silicone spray or furniture paste wax).

4. Apply UraGel 760 at the desired thickness (1/4″ to 1/2″ thickness) over the cured InstaGel Spray and allow 24 hours cure.

After 24 hours remove the InstaGel Spray rubber mold and the UraGel 760 back up mold from the surface. When you are ready to cast reproductions of the part lay the InstaGel Spray rubber mold into the rigid UraGel 760™ cradle back up mold. Reproductions of the wall surface can be made by applying urethane, plaster or concrete into your finished mold. The rigid back up mold will help your rubber mold maintain the proper shape when it is placed on the floor and filled with casting material. Always use mold appropriate release agents to prevent unwanted bonding of parts to your new rubber mold. Your mold will allow you to reproduce the exact shape and texture of the original wall surface from a variety of materials.

Other Uses

InstaGel Spray and UraGel 760 can be used as a bonding adhesive for wood, fiberglass, flexible foam, rigid foam and masonry components. Its paste consistency fills large surface gaps and holds pieces together, but hardens slowly enough to permit bonded parts to be fitted or adjusted while curing. These products will not dissolve EPS foams or styrene foams. Chopped fiber or fabrics can be with the UraGel 760 to increase strength. Fiberglass “Chopper Guns” are available which chop and simultaneously spew chopped glass fiber onto a surface as the UraGel 760 is applied.

InstaGel Spray bonds well to other materials and its rapid set time makes it an excellent flexible bonding adhesive for foam, wood or masonry production line assembly.

UraGel 760™ is also used as adhesive, surface filler and hard coating over expanded polystyrene (E.P.S.) foam.

UraGel 760™ can be painted with solvent base or water base paints (see Helpful Product Tips below). UraGel 770™ bonds well to other urethane materials and its fast set time makes it an excellent rigid bonding adhesive for foam, wood or masonry production line assembly.

Helpful Product Tips

It is easier to lift a paint job out of a silicone rubber mold than to later try and paint over cured urethanes. When customers use UraGel 760 to make reproduction ancient suits of armor or shields or masks they usually apply paint or primer inside the silicone rubber mold first before brushing in UraGel 760. When the UraGel 760 cures it will completely remove the paint layer from the mold, so your part comes directly out of your mold with a perfect paint job or primer layer. This trick works best with solvent based paints or primers. Water based paints will make the UraGel 760 bubble or foam as it cures in the mold. For this procedure we recommend using solvent based aerosol spray can paints from the local hardware store. Allow aerosol spray paint to fully dry or speed drying with heat gun. When paint is dry apply UraGel 760 into mold and allow full curing. When the cured UraGel 760 part is removed from the mold it will lift paint layer from mold and have a perfectly painted or primed surface. This in mold painting method saves time, produces better looking smother finish and is more durable and scratch resistant than ordinary painting.

When making brush-on rubber molds from wood, concrete, plaster, water based clays or natural stone, extreme care must be taken to prevent sticking of InstaGel Spray to master. Moisture coming out of wood, concrete or plaster will cause bubbles in your rubber mold and make spray-on silicone based release agents fail. You should paint or seal these materials and use heavier wax type release agents to prevent sticking of Instagel Spray molding rubber. When making brush-on molds paint or seal with a fast drying solvent based paint or sealer, let dry then use Johnson’s furniture paste wax or mold release wax to prevent sticking. Do not use car wax or liquid waxes because they usually contain water. Furniture wax or purpose manufactured mold release wax does not contain water.

Mixing Instructions

Have all materials at 70° – 85°F before mixing. Mix B component thoroughly in storage container each time before you begin spraying operations. Mix B component storage container thoroughly for 1 minute with electric or air powered drill and Jiffy® mixer drill attachment (Jiffy® mixer drill attachments are available from Industrial Polymers in 3 sizes for 1 gallon can, 5 gallon buckets and the largest mixer for 50 gallon drums), avoid whipping air into the part B solution as you mix. Close storage containers tightly after use, liquid components of Instagel Spray will absorb atmospheric moisture when exposed to air, causing the part A component to hardened in storage container or bubbles and foaming to occur when part A and B components are mixed together.

Clean Up

Follow equipment manufacturers directions for clean up procedures when you have complete

Spraying operations. Clean up should be done with solvents such as mineral spirits, Methyl Ethyl Ketone (M.E.K.) or acetone, never use water to clean when working with these products.

Water or moisture exposure will accelerate curing of these products causing bubbling and poor physical properties of cured product.

Storage/Shelf Life

InstaGel spray & UraGel 760 liquids should be stored in the original, unopened containers in temperatures between 64°F and 86°F (18°C and 30°C). Shelf life of materials when kept in unopened, sealed containers at the recommended storage temperature is six months. Container should not be opened until ready for immediate use.
