Mold Making and Casting: Casting resin in a urethane rubber mold

This is a prop cast in a PT Flex 70 urethane mold. The cast is made by mixing PT Flex 50 with EZ Flo 60 50/50. The result is a semi-rigid cast. 2300 mold release was used to prevent the resin from bonding to the PT Flex urethane mold. PT Flex is a new series of quick setting urethane rubber products.

Any chance you will carry Polyeurothane (sp) two part foam (density for somewhat fine detail sculpting)?

@0MrENigma0 We carry 2, 5, and 8 lb density rigid foam. We have a 3 and 5 lb flexible foam.
