Powder coating is much different from painting because there are no liquids or solvents. Therefore, it is the best coating for environmental friendliness. The powder over-spray has very high application efficiency because it is dry. The powder is converted from a powder to a continuous film by using heat on it. The powder coating materials are basically plastics that are ground into a fine powder. The coating powder is formulated with pigments, plastic resins, flow agents and other special ingredients to provide the preferred characteristics of the coating film.
Typical steps in the powder coating process for metal parts:
- Cleaning – the purpose is to remove grease, oils, polishing compound, wax, particulates, and light oxides from the surfaces of the part .
- Rinsing – This step is critical in the metal finishing process
- Phosphating (optional step to improve adhesion and corrosion protection) – Provides improved powder coating adhesion and acts as a corrosion barrier.
- Drying – High pressure blowers, air drying: high velocity air, heated air, combination of hot and high velocity air, and infrared drying
- Powder Coating
- Curing -The thermostat powder begins to melt, flows out, and then chemically reacts to form a higher molecular weight polymer in a network-like structure when it is exposed to elevated temperatures.
Powder Coating Advantages over liquid coatings:
- EPA friendly – it does not release hazardous VOC into the air and atmosphere like liquid finishes do.
- More attractive, tough, durable, cost-effective finish, and resistant to abrasion, corrosion and scratching.
- Lower rejection rates – no running, dripping – it is a dry process so it sticks efficiently and effectively.
- Color selection is virtually unlimited and Less fading
Powder coating is the process of coating metal with a plastic finish applied in powder form, and then baked to a fluid state, to bond it to the metal surface. Powder coating has many advantages over traditional liquid coating: It applies thicker without running, it’s better for the environment, and is easy to style with.
The powder coating process is very similar to a regular painting process except that the “paint” is a dry powder instead of a liquid. The powder sticks to the parts due to the grounding of the parts and electrostatic charging of the powder. Any substrate that can tolerate the heat of curing the powder and that can be electrically grounded to enhance charged particle attachment can be used. The powder flows and cures during the heating process.
Sandblasting is the best way for a part to be prepared for powder coating by powering away rust, dirt, old paint, grease, or any other element that may contaminate the part being coated. Sandblasting blasts away any contaminants that could affect the powder coating process using air pressure and millions of tiny particles.
