Bode FABUTIT® series of thermal hardeners, halogen-free, solvent-free. It can react with silicate binder in the range of 200-400 ℃ to improve the binding strength of silicate internal structure. The FABUTIT® hardener hydrolyzes in the alkaline environment of the silicate, creating a network of chains that harden the silicate bond. At the same time, the modified alkali ions in the original structure are replaced to obtain good water repellent and chemical resistance.
