| 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, 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.&& |
