Reynolds TASK® 5 Performance Liquid Plastics
Categories:	Polymer; Thermoplastic
Material Notes:	Product Overview: TASK™ 5 & TASK™ 6 low cost, high performance casting resins yield castings that are tan and virtually bubble free. These resins offer superior physical and performance properties compared to our popular Smooth-Cast™ Series of general purpose casting resins. Vacuum degassing is not necessary and they offer the convenience of a 1A:1B by volume or weight mix ratio. The differences between TASK™5 and TASK™6 are the pot life and demold time. TASK™ 5 & TASK™ 6 have high tensile and flexural strength, as well as high flexural modulus. These plastics were formulated for a variety of industrial applications including pattern making and making prototype models. These resins are designed for casting in thicknesses up to ½” (1.27 cm).
