TK 290 WB is a waterborne silane/siloxane, multi-substrate, salt, and water repellent. Engineered to prevent damage from environmental conditions including de-icing agents, salts, freeze damage, efflorescence, scaling, surface popping, and the damaging effects of acid rain. TK 290 WB is formulated to penetrate up to 1/8 inch (3.175 mm) and chemically bond with the substrate to become a permanent part, prohibiting salt, water, and chloride ion intrusion. This protection ensures the longest life-cycle to the substrate by preventing surface deterioration.
