Product Description
FOAM-iT!™ 4 BLACK
Smooth-On’s FOAM-iT!™ Series are two-component water blown rigid foams that are versatile and easy to use. FOAM-iT!™ products are available in 3lb., 4 lb., 5 lb., 8 lb., 10 lb.,15 lb. or 26 lb. per cubic foot densities. Parts A and B are measured and mixed in equal amounts by volume. The mixture is then poured into a mold or other form (apply release agent if necessary). The mixture will expand many times original volume (depending on which FOAM-iT!™ product you are using) and develop a uniform cell structure. FOAM-iT!™ 4 Black is pre-pigmented to a very deep black color.
All FOAM-iT!™ products can be used as a straight casting material, backfill material for hollow castings (adds structural strength) or as an encapsulation material, etc. They can be color pigmented with SO-Strong™, UVO™ or IGNITE™ colorants and are used for a variety of art/ craft, industrial design and special effects applications

EPSILON™ is a thixotropic epoxy coating that self thickens for brushing onto a variety of surfaces without sagging. Parts A and B mix together easily, and the mixture wets out uniformly. This product is not sensitive to moisture or humidity. EPSILON™ cures at room temperature to an impact resistant plastic which exhibits good compressive and flexural strength.
