Smooth-On Mold Max XLS is a tin-catalyzed silicone mold rubber that exhibits very low long-term shrinkage. XLS II molds last longer than other silicones in production when casting chemically harsh resins such as epoxies and polyesters as well as urethane foams.
Will reproduce the finest detail and is suitable for a variety of industrial and art related applications including making production molds for, reproducing prototypes, furniture, sculpture and architectural elements. Mold Max XLS can be thickened with THI‑VEX™ additive for brush-on applications.
