China Shanxi black stone smooth in the fight against UV, aging, durability, etc. performance is not outstanding, and the coating is easy to wear, from the floor, off, need regular repair. Due to the volatilization of organic solvents used in such protective products to form a cured film, the volatile substances are toxic, the products are flammable, and injuries and environmental pollution are easily caused during construction. Film coating protectants have been used by some businesses as fast-protection products, but overall they are still used in some low-end products.
This protective agent, including colored and colorless series, which is in the stone surface to form a dense protective film, so that stone and pollution sources isolated, so as to achieve the anti-fouling, waterproof, anti-oil purposes. Such products are generally dissolved or diluted by organic solvents some polymer material extraction protective agent, such as resin-based materials, silicones and so on. Compared with paraffin, its water resistance, stain resistance, life expectancy, the use of have greatly improved, but the air permeability is still poor, so that the water can not be drained stone and stone back, easy to make stone "disease", and The chemical coating will also change the texture and color of China's black glossy surface.
