Product Specification

Anti Scratch Colorful Powder Coating for Coil Steel, Special Use Thermoset Powder Coating

◎ Introduction

Coil coating is a kind of professional coating used to coat the surface of the steel plates and aluminum plates and make a pre-coated coil. It has changed the traditional method of coating metal sheets after forming and processing. Instead, the coil coating is pre-painted on the metal coil to form a color-coated steel plate for processing and is widely used in building materials, home appliances, and other fields. This "pre-coating" coating process has the advantages of simplifying the production process, improving construction efficiency, saving investment and transportation costs, and having better performance than the traditional "post-coating" process, which is one of the future development trends of the coatings industry.

To date, almost all pre-coated coils have been painted using liquid coil coatings. However, traditional liquid coil coatings contain organic solvents (VOCs) that are harmful to the environment. The powder coating does not contain any organic solvent and is a powdery substance with the advantage of zero VOC emission, and is one of the best choices to replace traditional liquid coil coatings.

In addition, as countries pay more and more attention to environmental protection, coating manufacturers are forced to develop products and technologies that can replace traditional liquid coil coatings. The main technical bottleneck of coil powder coatings lies in rapid coating and rapid curing. The former involves coating equipment and processes, while the latter involves the formulation and curing methods of powder coatings.

The powder coating for high-speed spraying of coil steel independently developed by our company for five years was successfully applied in a steel plate Co., Ltd. in Shandong, creating the technology of high-speed continuous spraying of powder coating for pre-coated steel plate. The coating speed reaches 60-120 m/min, surpassing the 40m/min production speed of similar powder coating units in Europe and the United States, reaching the international advanced level.

This product adopts a number of innovative technologies to solve a series of technical problems such as rapid curing of powder coatings (60-120m/mins), fast and efficient powdering, and high-speed production. Not only achieves the rapid spraying process of powder coatings at a line speed of 80m/min for the first time in China but also realizes the characteristics of good coverage, good leveling, and excellent performance under the condition of thin coating (20um-40um) of powder coatings. The product performance not only meets the technical standards of the coil industry, but also is superior to the current paint coating performance in key performances such as low-temperature bending, acid and alkali resistance, hardness, MEK resistance, edge cover, and aging resistance.
