Powder Coating is both an advanced and popular method of applying a decorative finish to a wide range of metallic products used by both industry and consumers. It is a decorative coating that is electrostatically applied to a surface as a fine powder then heated at between 180 and 200 degrees Celsius (substrate temperature) so that it flows and creates a consistent covering across the entire surface.
The result is a consistent, durable, high quality and attractive finish which is extremely resistant to scratches, cracking, peeling, UV rays and rust.
The powder coating process involves several steps;
- Abrasive blasting and/or solvent cleaning to ensure the surface is free of contaminants.
- Pre-treatment during which the product is treated with chemicals to further clean, etch and protect the surface and allow a good adhesion.
- Rinsing and drying
- Powder application with electrostatic guns
Curing – The component is heated to a particular metal temperature for a selected period of time after which the component cools and the coating forms a high quality, durable finished surface.
