                      Material Notes:
                      BC 8782 produces a high impact rigid 82 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 system is not recommended for use with tin cure silicones.Information provided by BCC Products, Inc.
