WC-775 A/B produces a high impact rigid 75 Shore D material that is commonly used to make clear or tinted castings 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 will generally require a mild post-cure. This product may exhibit a slight yellowing or color change when exposed to direct UV light. PRODUCT HIGHLIGHTS:
