There are three major trends in the international architectural coatings industry

China Coatings Online News Information
Today's coating industry is developing rapidly, new technologies and new products are emerging, market competition is increasingly fierce, the international architectural coatings industry presents three major trends:
water-based development
The proportion of traditional solvent-based coatings in China is gradually decreasing, and the development rate of water-based coatings is also very fast, but the low-grade varieties of polyethylene alcohol still account for a larger proportion. Improving the quality of water-based coatings and developing new varieties are important links to consolidate and develop water-based coatings. Focus on research and development should be ethylene acetate co-polypulestion emulsion, styrene-acrylic co-polylacelue and pure acrylic series as the base of latex coatings, and strive for durability, paint film smoothness, plumpness, construction, decoration and other aspects of a breakthrough; For its more mature epoxy emulsion, water-based polyurethane water-based substrates should continue to study high-performance water-based coatings to meet the special requirements of some.
To functional development
at present, in addition to fire prevention, anti-virus insecticidal, insulation and other existing low-quality functional coatings to increase efforts on scientific research, but also to step up research and solve the difficulties in building decoration, new problems. Composite technology will be an effective way to improve and meet all kinds of functions.the compounding of
(1) functions, such as elastic function and respiratory function: the excellent elastic emulsion and the surface modified microshell (ultra-microparticles) modified by hydro-hydrofurbic group are compounded, so that elastic ability coexists with permeability.
Elastic function and low pollution function of the composite: the temperature-reactive emulsion and coating film hydrotherapic technology composite, through the use of cross-linked molecular weight of the reaction latex, improve elongation and film density, so that elastic function and low pollution combined.
(2) Strengthen the basic research on acid rain-resistant rain coatings, solve the problem of acid rain corrosion of buildings, and strive to make a breakthrough in the matching of substation composite technology and related additives, to solve the problem of acid rain corrosion of buildings in China.
(3) the modified function of the substitly is compounded, the modified properties of the existing substits are modified, and the special functions are composited. Such as silicone modified acrylic weather resistance and moisture-cured polyurethane moisture permeability, in order to achieve the role of dual special functions.
To high-performance, high-grade development
as an ideal performance of coatings, not only to protect and beautify the substrate, but also to give the substrate itself can not have special functions, the use of some new substrates can make the coating to obtain very amazing high performance, high value-added, advanced effects, such as high weather-resistant fluorine resin coatings, for construction to achieve good results. Because fluorine resin coatings have excellent weather resistance, durability and chemical resistance compared to other synthetic resins. However, fluorine resins are more expensive and are extremely limited for building facades. Fluorine resin building coatings of asahi Nitro subsidiary of Japan, all performance is very good, but the raw material cost is about 80 yuan / kg. Paying attention to the development of fluorine resin in hydration, especially the fluorine resin modified co-polymer emulsion with fluoroethylene as the main body, it becomes a high-quality substation with good performance, high grade and acceptable price, laying the foundation for the development of high-performance, high-grade coatings. In the research of water-based polyurethane coatings, we should concentrate on the development of products. Polyamin energy is one of the high-grade materials with excellent performance, which makes it water-hydrated, which is not only in line with reducing pollution. Energy saving requirements, but also to maintain the characteristics of polyurethane itself.
addition, silicone modified acrylic coatings because of its excellent weather resistance, pollution resistance, chemical resistance, is an important direction for the development of China's architectural coatings. Powder coating because of non-toxic, good safety performance, will also be one of the development direction of high-grade architectural coatings.
