Poly 74-20

Poly 74-20 is a 1A:2B mix, A~20 hardness, polyurethane liquid rubber that cures in 8-16 hours and is designed for making high-performance, high-strength rubber molds for casting materials such as plaster (for millwork, home décor, etc.), wax (candles & lost wax varieties) and resins (polyurethane, polyester, epoxy - with proper release agents). Poly 74-20 is particularly well-suited for casting concrete (veneer stone, architectural cast stone elements, concrete countertops, ...) and often eliminates the need for concrete release agents.
