Product Description
FOAM-iT!™ 15
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!™ 15 is tack-free in about 4 - 6.5 minutes, developing handling strength in 20 minutes and full cure in 2 hours.
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.

Crystal Clear™ 202
Crystal Clear™ 202 is a water white clear and made specifically for applications that require clarity. These rigid urethane casting resins differ only in working and demold times. Low viscosity ensures easy mixing and pouring. Crystal Clear™ resins cure at room temperature* with negligible shrinkage.
CAUTION: NOT FOR HOME USE. THIS PRODUCT IS FOR INDUSTRIAL USE ONLY. With adequate local exhaust ventilation, respiratory protection is not normally required when using this product.
