EZ~Spray® 45 is a polyurethane rubber for spraying through the EZ~Spray® Junior Cartridge System. 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/epoxy resins, concrete, etc.
Yield - Each cartridge contains 3.75 lbs. (1.7 kgs.) of material. Assuming a thickness of 3/8" inch (0.95 cm), one cartridge of EZ~Spray® 45 will cover approximately 1.875 sq. ft. (0.17 square meters)
