MasterBrace® ADH 2200 | MCT CHEMICALS | MASTER BUILDER SOLUTIONS
MasterBrace® ADH 2200 is a two-component, non-slumping epoxy bedding and adhesive compound. It is a fast-curing material, filled with fine aggregates, ideal for a range of bedding, gap-filling, and concrete repair applications. This thick, easily workable compound can be applied using a trowel, spatula, or knife. Once cured, it exhibits high mechanical properties typical of epoxy, and it resists oils, greases, petroleum, salts, many acids, alkalis, and common corrosive media. The product does not shrink during curing and can be used in temperatures ranging from below freezing to 60°C. Its impact resistance and mechanical strength surpass that of concrete.
