Brush-On Molding Gels

Insta-Gel is a flexible, brush-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, Insta-Gel® thickens to a creamy spread-able gel which can be brushed onto vertical or overhead surfaces without sagging, or running. Within 24-hours Insta-Gel® cures to a tough rubber mold.  Before applying Insta-Gel®, 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 Insta-Gel® rubber mold from the master.

Spray On Molding Gels

Insta-Gel Spray is formulated for making large rubber molds where high volume production is required. This product cannot be hand mixed, it must be spray applied with special mixing and spraying equipment. The required equipment simultaneously mixes part A and B components together and sprays the product. Insta-Gel Spray molding gels cure more rapidly than our brush-on application rubbers (see our Brush-on Molding Gels product page). We recommend 2 types of spraying equipment for Insta-Gel Spray application; the first type is a small hand held dual cartridge spray gun the second is a much larger electric gear driven 2 component plural spray machine. The cost of the cartridge type spray gun ranges from $700.00 to $1500.00 USD. The larger electric spraying equipment ranges in price between $5000.00 to $12,000.00 USD. Both types of spraying equipment can be used with Insta-Gel Spray. The hand held cartridge sprayer may be purchased directly from Industrial Polymers Corporation or other suppliers.

The Insta-Gel and Insta-Gel Spray product lines offer a self-thickening gel feature. After mixing the liquid Component A and B the mixture thickens to a creamy buttery like consistency that allows for the application of polymer on vertical or uneven surfaces. The cured polymers form a tough and durable rubber liner that can be used for casting concrete and plaster parts.

Insta-Gel products are designed for “hand mixing” giving 15 to 20 minutes applications times.

Insta-Gel Spray products are designed for high volume rapid set applications and require plural component spray equipment.

Product Descriptions:

Insta-Gel 20 & Insta-Gel Spray 20

Very soft and flexible rubber used to create molds that require high elongation to release parts that are deeply uncut.

Primary uses include;

  • Casting of concrete and plaster parts
  • Molding wax for bronze sculpturing
Insta-Gel 30, Insta-Gel 40, Insta-Gel 50, Insta-Gel 65 & Insta-Gel Spray 30, Insta-Gel Spray 40, & Insta-Gel Spray 65

These products are the most common choice for concrete mold as they create a very durable rubber with excellent flexibility. Ideal for items that require higher mechanical properties. The product is available a range of hardness to accommodate the flexibility needed for the application.

Primary uses include:

  • Mold liners for casting of concrete and plaster parts
  • Molding wax for bronze sculpturing

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 Insta-Gel 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.

Insta-Gel 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 Insta-Gel Spray to create a hard supporting mother mold for their brush on rubber mold. The Insta-Gel Spray and UraGel 760 products are available in 5 gallon plastic pails and 50 gallon drum quantities.
