Smooth On

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 Ma™ 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).

Accessories: 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.

Available hardnesses:

  • Shore A10 – Mold Max 10
  • Shore A15 – Mold Max 14NV
  • Shore A20 – Mold Max 20
  • Shore A29 – Mold Max 29 NV
  • Shore A30 – Mold Max 30, Mold Max Stroke, Mold Max XLS II
  • Shore A40 – Mold Max 40
  • Shore A60 – Mold Max 60

Mold Max™ 14NV

Mold Max™ 14NV is a Shore 14A 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 Color is White. Mold Max™ 14NV will reproduce the finest detail and is suitable for a variety of industrial and art related applications including making molds for reproducing prototypes, furniture, sculpture and architectural elements.

Mold Max™ 14NV can also be used to create movie special effects. Cure time can be reduced with Accel-T™ cure accelerator. Mold Max™ 14NV can be used to cast a variety of materials including wax, gypsum, low melt alloys/metals and urethane, epoxy or polyester resins.

Important - Do not cast concrete into rubber molds made with this product. Concrete will not cure properly and inhibition will result.

Important - you must weigh Part A & B components using a gram scale to be successful with Mold Max™ 14NV.

Features

  • Mold Max™ 14NV has a fast cure time - 4 hours at room temperature
  • Mold Max™ 14NV does not require vacuum degassing - Low viscosity for easy mixing and pouring

Mold Max™ Stroke

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 30 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 molds, etc.

Features

  • Holds a vertical surface
  • 4 thin layers is all that is necessary to make a strong and durable production mold
  • Color: White

Mold Max™ XLS II

Mold Max™ XLS™ II is a Shore 30A 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.

Mix ratio is 100A:10B by weight. Pot life is 40 minutes and cure time is 24 hours at room temperature. Color: Blue.

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.

Vacuum degassing mixed material using a vacuum pump and chamber to remove entrapped air is recommended.

Features

  • Exhibits very low long-term shrinkage
  • High resistance to chemically harsh resins such as epoxies and polyesters as well as urethane foams
