Plastic powder is a thermosetting powder coating for electrostatic spraying. Phenolic resin is also called bakelite, and it can also be called bakelite powder. It is originally colorless or yellowish-brown and transparent, and it is often sold in the market with coloring agents to be red, yellow, black, green, brown, blue, etc. The color is in the form of granules and powder.

It is insoluble in water but soluble in organic solvents such as acetone and alcohol. The scope of application is the steps of powder coating in the hardware industry, automobiles and parts, anti-corrosion pipeline applications, building materials industry, sports equipment, and the first step is to determine the type of substrate that needs to be coated, then the powder coating is divided into The two types of thermoplastic and thermosetting are to choose the appropriate powder coating according to different substrates, so as to achieve the best coating effect.
