EpoxAcast™ 655 (formerly Metalset™ A-30) is a versatile aluminum filled castable epoxy resin that is very hard and strong. It is dimensionally stable, even when mass cast up to 512 in³ / 8,390 cm³. Maximum heat resistance is achieved using HT HIGH TEMP hardener (up to 225°F/108°C).
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!™ 26 is tack-free in about 4 - 6.5 minutes, developing handling strength in 20 minutes and full cure in 2 hours. FOAM-iT!™ 26 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.
