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 2A:1B by weight. 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!® 8 is a unique, selfskinning foam with a finer, more uniform cell structure than the other FOAM-iT!® products FOAM-iT!® 8 can be cast in blocks as a machinable prototype modeling board.
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.
