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.
