The growth of the powder coating business is affected by the toxicological effects of the raw materials used in the coating formulation and the saturation of the present market for powder coatings, being limited to general metal applications only. This has a strong influence on the long-term research programmes at both raw materials suppliers and powder paint producers. In the last decade of the 20th century, we witness appearance of several new types of toxicologically-safe powder coating systems on the commercial scale. At the same time, there is strong evidence of efforts to penetrate new market fields where powder coatings are not typically used. This includes the markets for automotive clear top coatings, can and coil coatings, coatings for industrial wood, plastics and paper. The new developments in the chemistry of powder coatings are followed by changes and improvements in the production technology for powder coatings as well as developments of new application techniques. This paper summarises the research work on chemistry, production and application technology of powder coatings and tries to extrapolate the tendencies in the years to come in order to predict the achievements and the impacts on the paint industry. 相似文献

Radiation-curable powder coatings are now in the early stages of commercialization. For years, the coatings industry has sought
ways to lower the curing temperature of powder coatings. UV-curable powder coatings offer the possibility of curing powder
coatings at temperatures as low as 120°C. Radiation-curable powder coatings also offer high cure speed and relatively low
energy consumption. As each application requires its own coating performance, two different maleate-vinyl ether-based binders
for UV-curable powder coatings have been developed. With these binders the balance between flexibility and hardness of the
coating can be adjusted with proper formulation. In this paper, the curing characteristics and coating performance of several
UV-powder coating formulations are described. In addition, a comparison between conventional powder coatings and UV-powder
coatings is provided.
