Product Description
Soma Foama™ 25
Soma Foama™ is a soft, two-component platinum silicone flexible foam that is versatile and easy to use. Soma Foama™ 25 is a higher density foam vs. original Soma Foama™ 15 which expands 2-3 times its original volume and develops a uniform 25 lb./cu. ft. cell structure (400 kg/m³). Vibrant colors can be achieved by adding Silc-Pig™ silicone color pigments. Cured foam is high heat resistance (will resist up to 350°F/176°C), water resistant, UV resistant and resists oxidation and ozone degradation.
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.
