Product Description

EZ-Spray® 45

EZ~Spray® 45 is a polyurethane rubber for spraying through the EZ~Spray® Junior Cartridge System. Refer to EZ~Spray® Junior manual prior to spraying this product. EZ~Spray® 45 can be sprayed onto vertical surfaces for making molds or is good for making fast molds of large surface areas. After a suitable thickness is attained, EZ~Spray® 45 cures overnight with negligible shrinkage to a durable mold rubber. Application of a support shell is achieved by spraying Smooth-On’s EZ~Spray® Plastic over the rubber mold after it has fully cured. EZ~Spray® 45 is suitable for casting a variety of materials including wax, gypsum, urethane or epoxy resins, concrete, etc.
