Smooth-On TASK 8 2 Gallon Kit Special Order

Article number: 66T8B
Availability: Out of stock

TASK® 8 is a heat resistant polyurethane resin system made specifically for prototyping / casting applications whichrequire thermal resistance of up to 263°F /129°C.TASK® 8 offers the convenience of a 1A:1B mix ratio and has a very low viscosity, so it is easy to mix and pour. Plastic cures quickly to a Shore 80D and exhibits good physical and performance properties. Heat curing this material is necessary to attain optimal heat resistance. Applications include making machine housings, thermo-forming and general prototyping / casting.
