WC-756 A/B is a two part, clear, 55 Shore D castable urethane that is commonly used to make clear or tinted parts of all kinds. When used at room temperature, castings 1/ 4 " thick or larger can be readily cast. Castings that are less than 1/ 4 " thick generally require a mild post-cure. PRODUCT HIGHLIGHTS:
