Poly 74-20 Gallon Kit (24 Lbs)

  • $185.00


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. Poly 74-20 molds can be poured as supplied or brushed-on by mixing in Poly Fiber II thickener.
Poly 74-20 liquid rubber is an excellent multi-purpose, economical mold material that will provide long mold life, durability and consistent performance under high volume casting applications.
