PMC-121/50 is a "wet-only" mold rubber that is long lasting and durable when used in a variety of applications including reproduction of ornamental plaster, precast concrete and ceramic case molds. Note: This rubber exudes oil that aids in demolding hard plasters and concrete and over time will shrink.
PMC 121 Series mold rubbers are easy to mix and pour and are exceptionally strong. They are suited for a variety of applications including making molds to reproduce sculpture and architectural elements, as well as for making special effects, toys and prototypes. These rubbers will meet the stringent demands of production casting of wax, plasters, concrete, resins and epoxies. Vibrant colors can be achieved by adding So-Strong and UVO Color Tints available from Smooth-On.PropertiesTechnical Properties
