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.
Ecoflex™ 00-35 FAST
Ecoflex™ 00-35 FAST is a soft, fast cure platinum-catalyzed silicone that is versatile and easy to use. Parts A and B are mixed 1:1 by weight or volume, pot life is about 2.5 minutes and rubber cures in about 5 minutes at room temperature with negligible shrinkage. Low viscosity ensures easy mixing and pouring. Rubber cures without "tacky" surface, is very soft, very strong and very "stretchy, stretching many times its original size. EcoFlex™ 00-35 FAST is off-white translucent and can be color pigmented using Silc Pig™ silicone color pigments.
