Poly 74-45 is a 1A:1B mix, A~30 hardness, polyurethane liquid rubber that cures in 16-24 hours and is designed for making high-performance rubber molds for casting materials such as plaster (millwork, home décor, etc.), cast stone, wax (candles & lost wax varieties), concrete and resins (polyurethane, polyester, epoxy - with proper release agents). Poly 74-45 molds can be poured as supplied or brushed-on by mixing in Poly Fiber II thickener or fumed silica. Poly 74-45 liquid rubber is an excellent multi-purpose, economical mold material that will provide long mold life, durability and consistent performance under repeated casting. Used extensively by art foundries and cast stone producers. When brushing, 74/75 Part X accelerator can be used to speed the process.

For professional use only. Use in a well ventilated area.
