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.
Mold Max™ 25
Mold Max™ Silicones are tin-cured silicone rubber compounds that have exceptional working properties and library life. Mold Max™ Silicones feature Smooth-On’s exclusive “Libra™” catalyst for long library life. Mold Max™ silicones can be pigmented with Silc Pig™ silicone colorants. Pot life for the Mold Max™ 25 is 60 minutes and cures overnight at room temperature.
Vacuum degassing mixed material using a vacuum pump and chamber to remove entrapped air is recommended.
