## Description

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

My child, supervised, loves making her own squishys!! Product works fast and is fun to try different things and shapes out with. Humidity and temps play a HUGE roll in the processing of the product just so you know

### ⭐⭐⭐⭐⭐ It always produces a successful mold.
