Using Smooth-On’s exclusive “V-Polymer®” technology, VytaFlex® urethane rubbers offer superior physical and performance properties for casting concrete. 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.
