Product Description
Mold Max™ 29NV
Mold Max™ 29NV is a Shore 29A tin-catalyzed silicone mold rubber that offers low viscosity, fast cure and long library life.
Mold Max™ 29NV does not require vacuum degassing. Mix ratio is 100A:10B by weight. Working time is 45 minutes and cure time is 6 hours at room temperature.
Mold Max™ 29NV 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. Cure time can be reduced with Accel-T™ cure accelerator. Mold Max™ 29NV 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™ 29NV.
TASK™ 4
TASK™ 4 is a unique polyurethane casting resin that is very strong when cast in Ultra-Thin sections ranging from 0.03” to 0.50”(0.075cm to 1.27cm). TASK™ 4 has a very low mixed viscosity, ensuring flawless pick-up of even the finest detail. Cured plastic exhibits very low shrinkage which is why this plastic has become a favorite of prototype and design professionals throughout the world. Pot life is 20 minutes and cure time is 16 hours at 73°F/23°C.
Vibrant colors and color effects are possible by adding SO-Strong™ color tints. Fully cured models made from TASK™ 4 are tough, durable, machinable and paintable. They resist moisture and mild solvents. Applications for TASK™ 4 include making prototype and architectural models, model toys, durable miniatures, ultra-thin mechanical parts and special effect props.
