Casting Compounds

Our casting compounds are currently used for safety surfacing, for the off shore oil industry, industrial and commercial applications. Very popular for 3-D signage and Movie Props due to the excellent finish and ease to work with. Duplicate natural substrates or cast panels simulating natural stone for architectural projects. Casting compounds are for excellent for encapsulation of sensitive electrical components, due to the strength and durability.

TrueCast is a flexible casting compound for concrete and masonry building concepts. It works very well on irregular parts and is our most versatile product.

The TrueCast Series is a high density, impact resistant, flexible, molding or casting resin product. This compound absorbs vibrations, resistant to specific elements and chemicals. Great for rubber seals, bumpers, and rollers. Insensitive to typical environmental moisture, low viscosity, high strength and low durometer, low residual surface tack, tough, high tear strength, good oil and grease resistance, good flow into detail, dimensional stable, hardness range from Shore 00A to 85 Shore A.

TrueCast XL & PureCast

These product lines offers a versatile range of high strength properties which allows for the production of extremely durable parts with excellent mechanical properties. These polymers fully cure at room temperature and required no post heating.

All of the TrueCast XL products are formulated to a 1 to 1 mix ratio by volume which makes for easy machine dispensing. The XL series ranges in hardness from 75 Shore A to 65 Shore D.

Here are a few attributes that that will determine the proper selection of the Polyurethane compound for the target application.

  • Abrasion Resistance
  • Wear Resistance
  • Impact resistance
  • Hydrolysis resistance
  • Flexibility
  • Elongation
  • Tear Strength
  • Tensile Strength

Product Descriptions:

TrueCast XL

Soft and pliable parts can be made with this family of polymers that have the combined features of high tensile & tear tensile with excellent elongation. In addition these polymers have outstanding resistance to water (salt & fresh) and resistance to abrasion.

Primary uses include:

  • Casting performance parts
  • Rubber rollers
  • Bumpers
  • Wheels
  • Pulleys
  • Abrasion control pads
  • Casting performance parts
PureCast Series

This family of polymers is similar to the TrueCast XL product but offer longer working time and better UV resistance when compared times to the XL Series.

These products are also used a coatings for marine ropes and slings for abrasion control

Primary uses include:

  • Casting performance parts
  • Rubber rollers
  • Wheels
  • Pulleys
  • Abrasion control pads
  • Bumpers

Rigid Casting Resins

Our rigid casting urethanes offer a variety of densities, hardness and working life to fit your application. Silicone rubber, aluminum, polyurethane or epoxy molds can be used for casting these products. A mold-releasing agent such as spray silicone or wax may be required to prevent bonding of these products to your molds. Our rigid castings urethanes are designed for easy hand mixing, no heating or cooking is required simply mix and pour into your mold.

ProtoCast 80R is our most popular low cost, low viscosity rigid casting resin. It provides a 3 to 5- minute working life and rapid 10 to 20-minute de-mold time. ProtoCast 80R rapidly produces high detail prototypes or display parts. It also simulates the density and appearance of natural white animal bone and antler or used with black pigment produces the appearance of carved ebony wood. ProtoCast products provide very low viscosity and cure quickly to a hard, impact resistant part.  ProtoCast products are recommended in applications where a “injection thermoplastic feel” is desired or white color is required. These products maybe hand or machine mixed. Various curing and work times are available. Hardness range from 60 Shore D to 85 Shore D

Semi-Rigid Casting Resins

PureCast™ is our strongest most abrasion resistant flexible casting product. PureCast™ provides the strength and durability of a heat-cured urethane in a simple to use RTV system. Recommended for casting industrial wiper blades, wheels, rollers and wear seals. PureCast™ provides you with the ability to cast high strength, flexible urethane parts in urethane or silicone molds. PureCast™ is available in five different hardness, mix ratios and cure times to best fit your manufacturing process. PureCast™ can be colored with our RV series pigments. We recommend using black or darker colors to prevent color change or applying a UV resistant coating. UV additives are available.

SpeedSet™ is a lower priced flexible casting polymer used for casting visual displays and medium durability working parts. It can be used for casting lightweight wall display panels to simulate a stone or fossilized appearance. Museums and amusement parks have used SpeedSet™ to create movable wall panels and backdrops for visual displays. Our customers have also used SpeedSet™ for encapsulating electrical components and in the manufacture of impact surfaces for golf clubs. SpeedSet™ is available in four different hardness, mix ratios and cure times to best fit your manufacturing process (see chart). SpeedSet™ can be colored with our RV series pigments to improve UV color stability. We recommend using black or darker colors to prevent color change (see TopCoat).
