Product Description
Econ™ 80
Econ™ 80 is an economical Shore 80A urethane rubber suitable for a variety of mold making and industrial applications. It is a lower cost, faster cure alternative to our popular PMC™-780. Physical properties are lower vs. PMC™-780. This is a no odor system that features a 1A:1B mix ratio and a low viscosity for easy mixing and pouring. Working time is about 13 minutes at room temperature, handling time is 6 hours and rubber cures overnight. Econ™ 80 is translucent and easily colored with SO-Strong™ or Ignite™ colorants. Econ™ 80 is used to make short run molds for casting concrete and resins, concrete stamping pads, rubber mechanical parts, coating fabrics, pour-in-place gaskets for industrial equipment and burial vaults. Important: To minimize air bubbles in cured rubber, vacuum degassing is recommended.

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.
