Poly 74-Series Liquid Mold Rubbers

Poly 74-Series Rubber MoldPoly 74-Series polyurethane liquid mold rubbers are soft to mid-range hardness, high-performance, room-temperature curing systems. They offer superior flexibility and toughness allowing durable molds to be made from relatively simple to highly detailed, complex models. The 74-Series liquid mold rubbers are supplied as pourable liquids but can be easily thickened to make brush-on molds.

These rubbers are commonly used in the following applications: Concrete Casting, Sculpture & Foundry, Architectural Reproduction & Restoration, Millwork & Ornamentation, Candle Making, Industrial Applications, Crafts & Hobby 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).
