High quality polycondensation Silicone with colorcodings.
Mold Max Silicones are tin-cured silicone rubber compounds that have exceptional tear strength, working properties and library life. Mold Max Silicones feature Smooth-On's exclusive "Libra" catalyst for long library life. They cure overnight and feature knotty tear propagation (if the rubber is torn, the tear quickly terminates in a "knot" reducing further mold damage).
Mold Max silicones can be thickened with Thi-vex thickener to achieve a paintable consistancy. A fast catalyst is available for the Mold Max 30. Ripped molds can be restored with Silpoxy silicone glue.

Mold Max® 14NV is a Shore 15A tin-catalyzed silicone rubber that offers low viscosity, fast cure and long library life. Mold Max® 14 NV does not require vacuum degassing. Mix ratio is 100A:10B by weight. Working time is 40 minutes and cure time is 4 hours at room temperature.
Mold Max® Stroke® is a brushable tin silicone rubber that self-thickens for making fast brush-on molds of almost any
model. Properly applied, it will hold a vertical surface and will reproduce the finest detail. Mixed 100A:10B by weight, rubber
quickly develops thixotropy and can be applied with a brush or spatula. Working time is 20 minutes, re-coat time is 45
minutes and cure time after the final layer has been applied is 16 hours at room temperature.
Mold Max® Stroke® silicone will not stick to most surfaces and will cure with negligible shrinkage to a strong, flexible
Shore 30A rubber. 4 thin layers is all that is necessary to make a strong and durable production mold for casting wax, gypsum,
concrete or resins (urethane, polyester, etc.). Applications include reproducing sculpture, architectural restoration, candle
Mold Max® XLS® II is a Shore 30A tin-catalyzed silicone 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. 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 molds for, reproducing prototypes, furniture, sculpture and architectural elements. Mold Max®
XLS® II can be thickened with THI-VEX® additive for brush-on applications.
Mold Max® XLS® II silicone can be used to cast a variety of materials including concrete, wax, gypsum, low melt alloys/
metals, epoxy or polyester resins (without using a release agent) and urethane foams.
