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.
FOR COMMERCIAL/INDUSTRIAL USE ONLY
URE-BOND™ II
URE-BOND™ II is a premium performance urethane adhesive compound that offers a strong flexible bond between many different surfaces. URE-BOND™ is ideal for adhering polyurethane rubber and other polymer products to many types of substrates (such as plaster, wood, cement, stone) and non-porous materials (such as glass, hard plastics and a variety of metals). URE-BOND™ II has also been used to repair torn polyurethane molds on a limited basis (with proper surface preparation). Working time is 5 minutes at room temperature (73° F / 23° C). Once mixed and applied, URE-BOND™ takes about 60 minutes to cure and yields a strong, flexible bond.
