Dry powder coatings: dual advantages of environmental protection and performance

As an emerging environmentally friendly coating, dry powder coating has been widely used in modern architectural decoration and industrial painting due to its excellent performance and environmental protection advantages.

The main ingredients of dry powder coatings include resins, pigments, fillers and additives. These ingredients are mixed, melted, extruded, cooled and pulverized through a specific process to finally form fine powder particles. When dry powder coating is used, it is adhered to the surface of the object to be coated by electrostatic spraying or fluidized bed coating, and is then baked, melted, leveled and solidified at high temperature to form a uniform and strong coating film.

Dry powder coating does not contain organic solvents, produces almost no volatile organic compounds (VOC) during the coating and curing process, and is harmless to the environment and human health. This environmentally friendly feature makes dry powder coatings very popular in the context of increasingly stringent global environmental regulations.

The utilization rate of dry powder coatings is as high as over 95%. The powder that is not attached to the surface of the object to be coated can be recycled and reused through the recovery system, which reduces material waste and production costs.

The coating film of dry powder coating has excellent corrosion resistance, abrasion resistance, impact resistance and weather resistance, and can protect the surface of the coated object for a long time and extend its service life. In addition, the coating film of dry powder coating has high gloss, bright color and good decorative effect, which meets the aesthetic requirements of modern decoration.

Dry powder coating is easy to apply, does not require thinners and primers, and reduces construction steps and time. The electrostatic spraying process makes the coating uniform, avoids problems such as sagging and brush marks, and improves the coating quality.

Because dry powder coatings do not contain flammable and explosive organic solvents, the risk of fire and explosion during the coating process is greatly reduced, improving construction safety.

Dry powder coatings are widely used in interior and exterior wall decoration, door and window frames, guardrails, metal roofs, etc. of buildings to provide a durable and beautiful protective layer and improve the overall quality and aesthetics of the building.

In furniture manufacturing, dry powder coatings are widely used for surface coating of metal furniture, wooden furniture and plastic furniture. Its excellent wear resistance and decorative properties add color to furniture products.

The application of dry powder coatings in the automobile industry includes the coating of bodies, wheels, chassis and parts, providing efficient protection and decoration functions and extending the service life of automobiles.

Dry powder coatings are widely used in the shell coating of home appliances such as refrigerators, washing machines, air conditioners, etc. Its corrosion resistance and aesthetics provide reliable protection and decoration for home appliances.

The application of dry powder coatings in industrial equipment includes the coating of pipes, valves, machine tools, engineering machinery, etc., to improve the durability and protective performance of the equipment and extend its service life.

Dry powder coatings are becoming an important part of the modern coatings industry due to their environmental protection, high efficiency, excellent coating properties and wide range of applications. With the continuous advancement of technology and the growing market demand, dry powder coatings will show greater development potential and application prospects in the future.
