Product Description

Mold Max™ 60

Mold Max™ 60 is a Shore 60A tin catalyzed silicone mold rubber formulated for applications requiring high heat resistance (up to 560°F/294°C). It features a low mixed viscosity and cured rubber exhibits very low linear shrinkage. Parts A & B are mixed 100A & 3B by weight. Pot life is 40 minutes and cure time is 24 hours. Applications include making foundry patterns, flat pattern reproductions and casting low-melt metal alloys such as tin and pewter.

EZ-Spray™ 35

EZ~Spray™ 35 is a platinum cure silicone rubber developed specifically for spraying through the EZ~Spray™ Junior Cartridge System. With no or minimal surface preparation, EZ~Spray™ 35 can be sprayed onto vertical surfaces for making fast rubber molds of large surface areas. After a suitable thickness is attained, EZ~Spray™ 35 cures in 1 hour with negligible shrinkage to a durable mold rubber good for production casting resins, foams, concrete, plaster and other materials. Application of a support shell is achieved by spraying Smooth-On’s EZ~Spray™ Plastic over the rubber mold after it has fully cured. Read the EZ~Spray™ Junior manual prior to spraying.
