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.
Formlastic™ 60
Formlastic™ 60 urethane is a durable mold rubber made for production casting of concrete. It features a low viscosity for easy mixing and pouring and cures with minimal bubble entrapment. Mix ratio is 1A:1B by volume, pot life is 40 minutes and the rubber cures with an ultimate Shore hardness of Shore 60A. Cured rubber is dimensionally stable (low shrinkage), offers good wear resistance and will render color accurate concrete castings.
IMPORTANT: This product does not contain mercury or quartz silica (non-carcinogenic).
