Stalite Special Solution Gypsum Hardener, 1 Gallon Bottle, 80151

Stalite Special Solution is a liquid gypsum hardener used in place of water when mixing gypsum products to create models and dies that are consistently harder, stronger, smoother, and more abrasion resistant. It promotes thin, bubble-free mixes, improves flexural strength, and can be used with all types of gypsum. The formula is freeze-stable and exhibits no significant setting expansion.
