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.
EpoxAcoat™ WHITE
EpoxAcoat™ RED, GREY, WHITE and NEUTRAL are thixotropic epoxy gel coats which are widely used for hand laminating and tooling applications. They are tough and strong surface coat resins which cure at room temperature and offer exceptional abrasion resistance. EpoxAcoat™ NEUTRAL is formulated “color neutral” specifically for adding color pigments and fillers. For high temperature applications (to 284°F / 140°C) use EpoxAcoat HT™ (see separate technical bulletin).
