| WC-782 A/B is an impact resistant, rigid, 82 Shore D material that is commonly used to make clear or tinted castings of all kinds. Parts that are 1/8" thick or greater can be easily cast at room temperature. Thinner sections generally require pre warming of the material, molds, and a post cure. |
