DESCRIPTION Hydrostatic press stone filmless maintenance agent is a maintenance hybrid comprised of a special kind of Oligomer Silsesquiloxane mixed in a water-based solution, formulated with powerful surfactants attributing to its excellent-resistance properties and a non-yellowing methyl silane hybrid, which reacts with the moisture and CO2 in the air, forming a nonsolvent based resin that penetrates into the substrate heightening its water proofing ability. Its ability to penetrate deep into the concrete, as deep as 3~5m/m, distinguishes it from other products on the market. Moreover, it can cause a chemical reaction with alkaline materials that produces crystals inside the concrete, that can fill and block the micro-vein within the concrete so as to reach the waterproof effect in depth; thus, the longevity of the building can be extended. APPLICATION Water, anti-pollutants and anti-weathering resistance for various surfaces such as: tiles, gaps between tiles, terra cotta, calcium silicate board , plasterboard ,bricks,concrete, natural and process stone, stone carving, stone washing, stone smoothening, stone cutting,sidewalks, parking plywood. ADVANTAGES * Highly active molecule that is eco-friendly, water-based and inorganic produces strong adhesive to the substrate after chemical cross-linking. * High permeability and excellent durability. * Non-yellowing, no stain contaminated, dirt can be easily washed off with water from rain or washing walls. * Excellent water repellent ability (the so-called Lotus effect) can effectively prevent from water permeating. * It is suggested to apply new coat regularly every three years; thus it can continue to maintain water-repellent and anti-pollutant functions.
