Product Description

TASK™ 3

TASK™ 3 low viscosity, high performance casting resin offers superior physical and performance properties compared to our popular Smooth-Cast™ Series of general purpose casting resins. Vacuum degassing is not necessary and it offers the convenience of a 1A:1B by volume (115A:100B by weight) mix ratio.

TASK™ 3 is white. It has high tensile and flexural strength, as well as high flexural modulus. This plastic was formulated for a variety of industrial applications including pattern making and making prototype models. This resin is designed for casting in thicknesses up to ½” (1.27 cm). TASK™ Plastics are moderately priced and are available in trial kits, one-gallon, five-gallon, 55-gallon drum and totes.

Rubber Glass™

Rubber Glass™ is a platinum-catalyzed silicone rubber product developed specifically for special effects and display applications. Two liquids (1 Part A + 1 Part B) are mixed together and poured into a container.

The mixture cures overnight to a solid water clear rubber that can then be easily broken or “crumbled” into pieces that look exactly like broken glass, ice or diamonds. Vibrant colors are possible by adding Silc-Pig™ liquid color pigments.

Rubber Glass™ can be used to create a variety of special effects (i.e. simulated broken glass where human contact is required) and model effects (i.e. simulated ice or water). It can also be used for electronic encapsulation applications.
