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.
Shell Shock™ SLOW
Shell Shock™ SLOW is a thixotropic plastic that self thickens when mixed and can be brushed onto a variety of surfaces or into rubber molds. When Parts A and B are mixed in proper proportion (1A:4B by volume or 1A:5B by weight), material cures at room temperature with virtually no shrinkage to a hard, durable plastic that exhibits good compressive and flexural strength. Fully cured castings are rigid and can be sanded, primed and painted. Color effects are possible by adding SO-Strong™ Color Tints.
Shell Shock™ plastics are ideal for making fast, lightweight rigid molds for creating silicone appliances and effects (use as a replacement for ‘stone molds’). You can also brush a “gel coat” into a rubber mold and back it up with rigid foam, creating a highly detailed lightweight casting. These products can also be brushed onto styrofoam (polystyrol) as an impact resistant coating that can be sanded, primed and painted (minimum 3 coats recommended). Shell Shock™ plastics can also be used to make rigid support shells for brush on rubber molds.
