Product Description
TASK™ 11
TASK™ 11 urethane casting resin is a semi-rigid plastic (has some flexibility) that is strong and very tough. Originally developed for high impact tooling (drop hammer punch), TASK™ 11 also offers good abrasion and chemical resistance and is ideal for a variety of industrial applications.
This product is suitable for some FDA/USDA applications - dry food contact only.
TASK™ 11 applications include making abrasion resistant parts, foundry patterns, encapsulation, roller facings, metal bonding and vibration pads.

TASK™ 5
TASK™ 5 is a low cost, high performance casting resin, which yields castings that are tan and virtually bubble free. This resins 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 or weight mix ratio.
TASK™ 5 has a 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 resins was designed for casting in thicknesses up to ½” (1.27 cm).
