Exterior wall coating development prospects need rational guidance

In China, exterior wall decoration materials for a long time in ceramic tile, Mosaic, marble and curtain wall and clay brick is given priority to, only a tiny fraction of exterior wall coatings. With the developed countries, compared to 80% or more of the outside wall decoration USES the exterior wall coating gap is larger. In response, the industry analysis, points out that the main reason is the low level of exterior wall coating quality, use 2 - Three years will be lost, fading, peeling, peeling, pulverization, such as aging, seriously affect the exterior adornment effect. For a long time, coating formed coating is low, not suitable for senior decoration requirement of consumption idea. At the same time, many development enterprise behavior also makes the low quality of the making of exterior wall coatings in the market, thus affecting the development of the industry. Although the current situation is worrying, coating industry brand enterprise is still in the unremitting efforts to guide the market. For a long time, exterior wall coating construction seems to be 'low-end' project. Although there is no real statistical data, but this spread in the construction industry. Chinese architectural coatings industry always seem to be walking in a strange circle. This concept is very advanced, but the quality and application of no change. A circle is a policy support and difficult to break through the contrast between the high quality products. As early as a few years ago, Beijing, Shanghai, chongqing, jiangsu, dalian and other local governments will make clear a regulation, high-rise buildings must be decorated with exterior wall paint, Mosaic is prohibited. The use of ceramic tile is limited in the residential building external wall, and promote the use of high-quality exterior wall coating. The policy to encourage and enhance the confidence of the firm. The influx of a large number of enterprises to 'active' market. However, due to the paint industry low barriers to entry, the variable quality of production enterprises, inadequate regulatory policy, low price competition, although many products, from styrene acrylic coating to silicone and fluorocarbon coatings, service life is 3 - 10 - 15 years, but the market tend to focus on the low-end products, high weather resistance and resistance to relatively less polluting products. Embarrassing, coated with low quality of paint building in a few years old and soon become angry. So while the architectural coatings have good prospect, but they do not have very good reputation. Some developers of the low price strategy aggravated the situation. In many cases, to reduce procurement costs, some projects of exterior wall coating cost is only 5 yuan/m2 ( Should be in normal coating cost 15 yuan/m2) , 1 kg of coating can be painted 3 ~ 4 m2, ( 0. 3 kg/m2 is the normal dosage of emulsioni paint; The dosage of the stone coating for 4 kg/m2) , even if the water seepage is more, also can brush to 5 m2, thickness of 0. 1 mm, it cannot block the sunlight and rain erosion. If a building's facade adopts thick paint technology, 3 kg paint is brushed on the 1 square meters, about 2 mm thickness, this technology can not only make the wall permeability, anti-fouling, and won't craze. In China, however, only 10% of the construction market share the use of this technology and better products. More often, because the price factors and the influence of many developers bid policy, we can only exit. Ada of many high quality and good technical coating products can only temporarily in the lab, can't enter the market. Although the situation is worrying, coating industry brand companies are still trying to guide the market. 'In terms of paint products, there is a difference between high, medium and low grade. Better product performance, such as fluorine carbon coating system, has the very good weatherability and buy the color of light, paint film of the normal service life of 20 years. Second, silicon a crylic-acid system also has good weatherability, paint film can be used more than 8 years. Low-end products due to poor weather resistance, there will be 2 ~ 3 years of fade.
