Classification And Process Of Metal Powder Coatings

Metal powder coating film shows metallic luster with a gorgeous multi-color effects as well as outstanding protection features

. It provides a colorful decorative appearance for the automotive, appliance, instrumentation and other high-end industries. Now the classifications of metal powder coatings are according to the appearance effect of the coating and metallic paint types or coating functions.

According to the flatness of coating appearance, it can be divided into planar and texture two major types. According to the appearance of coating gloss effect, planar metal silicon powder coatings can be divided into high-gloss, flash (colorful flip-flop), and metal effect of several types of flash and metal effects products have been applied to the topcoat of the limousine. According to the texture of the appearance of the coating metal powder, coatings can be divided into hammer, sand patterns, and stripes.

According to the film's main function is divided into two types of decorative and protective, decorative products are common decorative and ornamental; protective products of the weathering resistance and anti-static (conductive). The formation of powder paint coating metal effect is achieved by adding metallic pigments.

Metal powder coating formulation design involves many factors, the main product metal color, the effect of film art, the production process, curing conditions, changes in any conditions on the original formula to re-design some of the key trade-offs and the amount of additives The size was also significantly affect the appearance of the nickel powder coating. Dry-mixed formula is metal pigments and various additives and the base material powder in proportion to the design, production was weighed according to the ratio of feed materials, all kinds of product design and process parameters and processes, mixing, heating, bonding, cooling, powder body treatment and screening and other production operations.

Joined with conductive metal paint, the metal powder coatings have been greatly different from the conventional powder coating, spray powder conductivity of strong, can easily cause a short circuit, burning gun, hit man accident, the adhesion is poor products more serious ; metal powder coatings are not suitable for use friction and electrostatic spraying method, the friction positive and negative charges combined with the role of neutral charged powder particles, the total powder with a decrease in power consumption, quality of construction is difficult to guarantee.

The application of nonmaterial and technology in powder coatings industry promotes the practicality development of GMA acrylic resin for metal powder supplier. It provides the basis of the base material for the development of metal powder coatings in automotive high-decorative industry. With continuous enhancement of global awareness of environmental protection and the promotion of national environmental regulations, powder coatings will has more rapid development in worldwide. The metal powder coatings will also go towards the direction of sustainable development with high decorative and strong efficacy.
