Castaldo Rapido Mold - Silicone Jewelry Molding Rubber - 5lb Box

Castaldo Rapido is a specialized silicone molding rubber that cures much faster than traditional organic rubber in a vulcanizer. This 5 lb box provides a material that combines the high-detail capture of silicone with the durability needed for mass production. It is designed to be tough yet flexible, making it easier to remove complex jewelry patterns without tearing the mold. Using Rapido can significantly shorten your mold-making cycle, allowing you to move from model to wax production in record time.
