FOAM-iT!® expanding foams are easy to use and cure rigid and strong. They can be used as a lightweight casting material, backfill material for encapsulation or to make hollow castings. You can color them with SO-Strong®, UVO® or Ignite® colorants for a variety of art/craft, industrial or special effects applications.

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!® 5 is tack-free in about 4 - 6.5 minutes, developing handling strength in 20 minutes and full cure in 2 hours.

Crystal Clear

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.

Pouring & Curing - For best results, pour your mixture in a single spot at the lowest point of the containment field and let the mixture seek its level. Allow space in the containment field for the foam to grow as it expands to its ultimate volume. Allow foam to cure for at least 20 minutes before handling.

Improving Surface Finish & Minimizing Voids With Back Pressure - Use a board that will completely cover the mold opening. Using a 3/4” (2 cm) drill bit, drill 3 holes in the board spaced a few inches/cm apart. Make sure that when the board is placed over the mold opening the holes are over the mold cavity and rising foam will be able to make it through. Apply Ease Release® 2831 thoroughly to both sides of the board and into the drilled holes. Mix and pour FOAM-iT!® into mold cavity and place board over mold opening. Secure board firmly in place (mold straps may be necessary). As foam rises in the mold cavity, some foam will grow out of the drilled holes. After the foam stops growing, you can let go of the board. Do not handle for at least 20 minutes. You can then cut excess material that came through holes and gently remove board and casting.

Fully Cured Foam can be sanded, machined, drilled, etc. (wear NIOSH approved respirator). Foam can also be primed and/or painted.
