powder coating development difficulties

Nowadays people pay more and more attention to environmental protection. The requirement 

for environmental protection is a great power to promote the development of powder 

coatings, because manufacturers are looking for ways to reduce the product VOC, so in some 

areas of the natural alternative to the liquid paint. Paint with low VOC content, clear 

easy to spray paint can be recycled. History of coatings used in advanced countries is 50 

years, our country only 30 years, developed countries on the issue of industrial pollution, 

found earlier, so very early on the development of the control of volatile organic compound 

emissions regulations, promoted the rapid development of the coatings, the global demand of 

powder coatings has been holding strong.

Powder coating has the following advantages: (1) full closure of the vamp system to avoid the pollution of dust and fiber in the surrounding environment and the influence of coating the cleanliness of the particle switch can control (3) of the coating has excellent triboelectric properties. The powder in the spraying process can seep through to the hard to reach the site. The film thickness can obtain low thin film and processing temperature, can prevent glycidyl methacrylate oxidation of glycerol ester (GMA) acrylic acid resin, in order to prevent yellowing coating. The new process can be pre reaction is reduced to a minimum, in favor of powder flow and leveling, good reproducibility and is advantageous for low temperature curing coating processing and the crystalline polymer coating preparation, improve the storage stability, lower melt 

viscosity, mobility of transparent coating and flow flat has a great influence.

China small scale powder coating enterprises is too much. The homogeneity trend of most small scale enterprises serious disorderly competition caused by flooding, the paint industry good to 

fall. Cause this situation, there are historical roots, but also the government responsibility, as the main enterprise, of course, can not escape the relationship. To 

reverse this situation, there are three main ways: one is the survival of the fittest in 

the competition emerge of itself and perish of itself. Two is the government guidance and 

norms, to carry out industrial policy autonomy, including regulation. Three is the 

enterprise to take the difference of development, to do the best, looking for market 

segments in the small world.
