powder coatings
and coating technology applications are expanding. According to reports, due to the huge environmental pressure, powder
coatings
continue to replace liquid
paints
has become the mainstream of today, with the powder coatings and coating technology improvements, powder coating applications will be greater.
improvements in powder coatings and coating technology have been mainly due to increased demand in the white automotive, home appliance and general industrial sectors, including improvements in raw materials, powdering and coating technologies. Powder coating is expanding in the automotive industry, with powder coatings for automotive chassis, interior parts, wheels and body parts. Technical improvements to automotive powder coatings include: transparency, adhesion, leveling and UV resistance of transparent powders: reducing curing temperature as much as possible while ensuring the appearance and performance of powder coatings; As well as a variety of coating technology (such as robotics, air flow control technology and high powder rate technology).
according to the introduction, powder coating pre-coated metal plate (roll material) in the home appliance industry applications are growing rapidly, requiring powder coatings in 25 to 60s to complete the melting, flow leveling and curing process, while maintaining a good coating appearance and a variety of resistance. Powder coatings for home appliances must have a certain post-molding characteristics, the molding degree depends on the end-use. Coated sheets should be stacked together, ordinary metal sheet thin coating film coating line speed should reach 30 to 80fpm, coil coating line speed should reach 100fpm. In addition, airflow control (or reduction), powder rate or charge transfer rate should be controlled in optimal condition.
's improvement in the appearance of curing coating film at high coating line speed is the main focus of the improvement of home appliance powder coating technology, which involves the matching of infrared wavelength/light intensity with coating and substrate, rapid flow leveling of conve current heating and induction heating curing methods, a solidification procedure with good continuity of powder coating surface, and the cleanliness of the entire curing system.
The development of the automotive and home appliance industries has promoted the development of special powder coating systems and coating technologies, and the application of special powder coatings for different processes in ordinary
-industrial coatings
is growing, gradually entering areas that were previously difficult to get involved in (due to excessive color requirements, excessive coating speed, severe paint seepage, excessive coating, etc.). Powder coatings in the general industrial coatings market are another bright spot because they offer a wide range of products to meet the needs of many small customers. Global
Coatings Network
understands that the increasing number of powder equipment suppliers and raw material suppliers has also prompted many regional paint suppliers to add powder coating production lines, while the mature European market continues to have new powder coating raw materials and
coating equipment
facing. In short, the increase in the number of suppliers is most beneficial for small and medium-sized powder users, who can obtain stable prices of raw materials, products more practical. However, the development of large powder customers often benefits only a few specific suppliers, making them more relevant to powder coatings, coating processes, and end users.
noun: Powder coating is a new solvent-free 100% solid powder coating. It has the characteristics of solvent-free, non-polluting, recyclable, environmental protection, saving energy and resources, reducing labor intensity and coating mechanical strength.
