Product Description
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.
Alja-Safe™
Safe to use Alja-Safe™ is the world’s first alginate molding powder that does not contain crystalline silica (a known carcinogen). Alja-Safe™ is perfect for making single-use molds of the face, hands and other body parts. It captures detail better than other alginates, giving you a more accurate reproduction of your original.
Certified Skin Safe - Material is skin safe and certified by an independent laboratory.
