Poly 75-Series polyurethane liquid mold rubbers are mid-range to firm hardness (Shore A60 – A90), high-performance, room-temperature curing systems. They offer superior strength, toughness and abrasion-resistance that result in durable molds that capture and reproduce exact textures and the finest detail from any model. Poly 75-Series rubbers offer an optimum blend of economy and performance.

These rubbers are commonly used in the following applications: Concrete Casting, Architectural Reproduction & Restoration, Industrial Applications, Theming & Display, and much more.

Plaster and wax can generally be cast in polyurethane molds without any release agent, but most concrete mixes and polyurethane resins require a suitable release agent (e.g., Pol-Ease® 2300 Release Agent).
