Product Description
VytaFlex™ 60
Using Smooth-On’s exclusive “V-Polymer™” technology, VytaFlex™ urethane rubbers offer superior physical and performance properties for casting concrete. VytaFlex™ urethanes are available in 10A, 20A, 30A, 40A, 45A, 50A and 60A Shore hardness’s and feature convenient one-to-one by volume mix ratios.
Vacuum degassing is not necessary and VytaFlex™ rubbers cure with negligible shrinkage to a durable rubber that will last in production.
VytaFlex™ mold rubbers work especially well for casting pigmented / colored concrete. Molds made with VytaFlex™ Series urethanes will render accurate and uniform colored castings.

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. 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.
