Waterproof material on the market, there are two categories: First, the polyurethane waterproof coating. Such materials are generally made from polyurethane and coal tar as raw material. Its volatile petroleum coke toxic, not easy to remove k11 waterproof coating, so in 2000 was banned in China. Still selling polyurethane waterproof coating, instead of coal tar pitch is used as a raw material. However, when using this paint, the general contain toluene, xylene and other organic solvents to dilute, and thus toxic; the other is a polymer cement-based waterproof coating. Waterproof coating means the coating film forming a coating to prevent seepage of rainwater or groundwater. Waterproof paint coatings can be divided into states and forms: emulsion, solvent-based, reactive and modified asphalt. The first solvent-based coatings: These paints a wide range of quality stuff, but the high cost, poor security waterproof coating, use is not very common. The second category is water emulsion and reactive polymer coating: the process is difficult in this type of coating various reinforcing agents, fillers, polymer elastomer dispersed uniformly in colloid polymer cement waterproof coating, only can be used with a small amount of polishing agent, reactive two-component polyurethane waterproof coating prices, perishable, high cost. The third type of plastic-type modified asphalt: These products can be UV resistant, high temperature resistance, but the elongation at break slightly worse.
