The application of powder coatings in aluminum building materials shows new trends

Powder coating because it is completely solvent-free, can be converted into coating film, its coating efficiency is high, protection and decoration of good comprehensive performance and other advantages, has been widely valued. Metal building materials are widely used in all aspects of buildings because of their excellent durability, decoration and processing formability. Aluminum building materials because of its good processing performance, light weight and so on, the amount of metal building materials accounted for more than 80% of

. Since the advent of powder coatings in the early 1970s, their application in aluminum building materials has grown rapidly.
, the application of powder coatings in aluminum building materials has been extended from Europe to the Americas, Australia, the Far East, the Middle East and Africa. In the coating of aluminum building materials, representative powder coating varieties of epoxy resin, polyester resin, acrylic resin and silicone resin powder coating. As an application, such as some aluminum frames, doors and windows, balconies, corridors, partition panels and other highly corrosive aluminum building materials, most of the use of polyester, acrylic powder coatings. In addition, because epoxy powder coating has excellent adhesion, corrosion resistance, but slightly less weather resistance, it is generally used indoors or as a primer.
Recently, with the development of domestic powder coating research, there are currently new varieties of powder coating has entered or is about to enter the aluminum building materials market applications:
(1) fluorocarbon powder coating
has developed a general powder coating production line can be applied thermo-solid fluorine resin powder coating coating. This thermoo-solid fluorine powder coating is more weather-resistant, photoresistable and durable than epoxy powder coatings, polyester resin powder coatings, and acrylic powder coatings, and can even be compared to solvent-based fluorine coatings.
(2) high weather-resistant silver powder coating
silver powder coating has been due to weather resistance problems, has not been able to get involved in aluminum building materials applications, and with the powder coating technology and upstream raw materials research and development progress, aluminum powder pigments have made considerable progress, aluminum silver powder acid-alkali resistance, salt spray resistance and anti-aging properties to obtain quality improvement, the use of multi-layer coating technology aluminum silver powder pigment to fully meet the application requirements of the aluminum market. Therefore, high-resistant flash silver powder coatings came out, into the high-profile aluminum building materials applications, as a pioneer of industry innovation, has successfully developed high-weather flash silver powder coatings for our customers to choose to use.
(3) high weather-resistant water-print powder coating
high weather-resistant water-print powder coating as a new special product of the paint, has been in the forefront of domestic research and development, in 2015 the new high weather-resistant water-print powder coating, its comprehensive performance fully meets the requirements of aluminum building materials, so with the development and promotion of this kind of water-resistant water-print powder coating, high weather-resistant water-print powder coating will also be widely accepted and applied by the aluminum building materials market, it is worth looking forward to!
