Description

Powder coating is a type of dry finishing process that has become extremely popular since its introduction in North America in the 1960s. Representing over 15% of the total industrial finishing market, powder coating is used on a wide array of products. Here are the key points that describe powder coating:

• Process: Powder coating involves applying a dry powder to a surface, which is then heated to create a smooth, hard finish. The powder can be applied using an electrostatic spray gun or by dipping the part in a fluidized bed of powder.
• Types of Powder: These powders melt and flow when heated but do not change chemically. They can be remelted and reused.
• Thermosets: These powders undergo a chemical change when heated, creating a strong, irreversible bond. They cannot be remelted.
• Durability: Powder coating creates a hard finish that is tougher than conventional paint.
• Environmentally Friendly: It emits negligible volatile organic compounds (VOCs) and overspray can be recycled, reducing waste.
• Versatility: Suitable for a variety of materials, including metal, plastic, glass, and MDF (medium-density fiberboard).
• Aesthetic Variety: Available in numerous colors, textures, and finishes, from matte to high gloss.
• Applications: Widely used in automotive, appliance, architectural, furniture, and industrial sectors. Common items include wheels, outdoor furniture, bicycle frames, and machinery parts.
