BJB Polyurethane WC-766 A/B

About
WC-766 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. Product Highlights: Exceptional clarity, UV and oxidation resistant Tough and impact resistant 15-20 minute working time No odor, solvents or exudates Good exterior weatherability&&
