*TrueCast also available in hardness range from 0-10 Shore A to 85 Shore A. Learn more about TrueCast Series in the tab below.

ProtoCast Series

Casting compound resin for the look and feel of injection molded high definition-prototype parts. This is a low viscosity, rapid setting, rigid urethane resin which cures quickly to a hard, tough impact resistant casting, with a thermoplastic feel. Protocast is non-sensitive to moisture after cure and will bond to itself if stage pours are require. This product eliminates the need for expensive metal injection molds. Protocast has been specially formulated for casting high definition or 3 dimensional prototype parts or limited run production work for the look and feel of thermoplastic. This product will not become brittle when used to mold a thin walled part. These products maybe hand or machine mixed. Various curing and work times are available. Hardness range from 60 Shore D to 85 Shore D

PureCast Series

Two component castable polyurethane elastomer resin contains no TDI or MOCA. Insensitive to typical environmental moisture and low shrinkage it provides the strength and durability of a heat cured urethane in a simple RTV system. It provides the ability to cast high strength, flexible parts in a urethane or silicone mold. Used in core box liners, metal forming pads, industrial parts, and abrasion resistant pads bumpers, wear seals, industrial blades, and concrete stamp dies. Pure Cast products are also, an abrasive resistant coating for ropes, buoys, netting, marine and industrial projects.

Speedset

Semi flexible polymer casting resin used in visual displays. This resin has medium durability for working parts. Finished product is lightweight, prefect for panels and wall displays simulated stone or fossilized appearance. Due to the high impact resistance it has been used on the strike face of golf clubs. Several versions of Speedset are currently used, to encapsulate electrical components.

A low viscosity, rapid setting casting urethane resin used to achieve high strength and durometer. The rapid cure allows for quick de-mold times. Speedset is easy to use requiring only hand mixing and applying. This very quick setting product is available in various working and de-molding times. Hardness range from 35 Shore D to 70 Shore D.

TrueCast Series

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.

Rigid Casting Resins

Our rigid casting urethanes offer a variety of densities, hardness and working life to fit your application (see chart on this page). 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.
