Mold Max™ XLS™ II is a Shore 30A tin-catalyzed silicone mould rubber that exhibits very low long-term shrinkage. XLS™ II moulds last longer than other silicones in production when casting chemically harsh resins such as epoxies and polyesters as well as urethane foams.
Mix ratio is 100A:10B by weight. Pot life is 40 minutes and cure time is 24 hours at room temperature. Mold Max™ XLS™ II silicone will reproduce the finest detail and is suitable for a variety of industrial and art related applications including making production moulds for reproducing prototypes, furniture, sculpture and architectural elements. Mold Max™ XLS™ II can be thickened with THI‑VEX™ additive for brush-on applications.
Important: you must weigh Part A and B components using a gram scale to be successful with Mold Max™ silicones.
Vacuum degassing mixed material using a vacuum pump and chamber to remove entrapped air is recommended.
Exhibits very low long-term shrinkage
High resistance to chemically harsh resins such as epoxies and polyesters as well as urethane foams.
