FastCast™ is a 2-part, clear casting urethane resin, which turns white once set. The product is odourless and sets in 10 minutes (@ 70°F / 21°C). Cast pieces can be removed from the mold within 10-15 minutes. Cured pieces are hard yet durable and can be drilled, sanded, carved, tapped, machined, stained and painted with acrylics. Ideal for fast prototyping and quick duplication of original pieces.
