| WC-765 A/B is a two part, clear, colorless 65 Shore D urethane castable product that is commonly used to make clear or tinted parts of all kinds. When used at room temperature, castings 1/8" thick or larger can be readily cast. Castings that are less than 1/8" thick generally require a mild post-cure. This product may exhibit a slight yellowing or color change when exposed to direct UV light. |
