FastCast is a two-component clear urethane casting resin, which turns white once set. Easy to use, 1:1 ratio and is odorless. Ideal for casting, quick prototyping, miniatures, models, taxidermy and more. FastCast sets to a hard cast in approximately 10 minutes at 70°F. Once cured, FastCast can be drilled, sanded, shaped and painted. It works great with Techno Glow glow powders & color dyes.
