TK-290 is a low viscosity, multi-substrate, salt, and water repellent. Available in standard VOC and a Low VOC option, TK-290 series is engineered to prevent damage from environmental conditions including de-icing agents, salts, freeze damage, efflorescence, scaling, and surface popping. TK-290 is a solvent-based formulation to penetrate up to 1/4 inch (6.35 mm) and chemically bond with the substrate to become a permanent part, prohibiting salt, water, chloride ion, and acid rain intrusion. This protection ensures the longest life-cycle to the substrate by preventing surface deterioration.
