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.
Ecoflex™ 5
Ecoflex™ rubbers are platinum-catalyzed silicones that are versatile and easy to use. Ecoflex™ rubbers are mixed 1A:1B by weight or volume and cured at room temperature with negligible shrinkage. Low viscosity ensures easy mixing and de-airing. Dispense using our convenient dispensing cartridges. Cured rubber is very soft, very strong and very “stretchy”, stretching many times its original size without tearing and will rebound to its original form without distortion.
