| WC-755 A/B produces a 55 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 generally require a mild post-cure. This product may exhibit a slight yellowing or color change when exposed to direct UV light. |
