Axis Fencing - Powder Coater
Ensure that all the correct steps are followed in the powder coating process.
Many powder coaters do not follow the correct procedure when applying powdercoat to a fence or gate which results in an inferior finish. By not following all the steps in the process, the powder coat can flake or peel off in a very short space of time.
Below is some information of what powder coating is and the correct procedures for applying powder coat.
Axis Fencing Group uses Precision Coating Services as their powder coaters who follow these correct procedures.
What is Powder coating?
Powder coating is an advanced method of applying a decorative finish to a wide range of metallic products used by both industry and consumers. The powder is electrostatically sprayed onto the surface to be coated and then placed in a curing oven where the product is heated and fuses into a smooth coating. The result is a uniform, durable, high-quality, and attractive finish which is very resistant to scratches, cracking, peeling, UV rays and rust.
The entire powder coating process should involve several steps.
1. Abrasive Blasting, stripping and/or solvent cleaning to ensure the surface is free of any oils, dirt, rust or foreign matter
2. Pretreatment during which the product is treated with a chemical to further protect it and improve the surface for powder coating
3. Rinse and Dried
4. Powder is applied with an electrostatic gun
5. Curing – takes place when the product is heated at a certain metal temperature for ten minutes after which the product cools and the coating forms a high quality, durable finished surface.
Pre-treatment - 8 stage process:
1. Alkaline clean
3. Towns water flush
4. Iron phosphate
6. Towns water flush
7. Non chrome acid rinse
8. Demineralised water rinse
What are the advantages of Powder Coating?
Good looking durable finish
Powder coating gives consumers, businesses, and industry one of the most economical, longest-lasting, and most color-durable quality finishes available.
Powder coated surfaces are more resistant to chipping, scratching, fading, and wearing than other finishes. Colour selection is virtually unlimited with high and low gloss, metallic, and clear finishes available. And colours stay bright and vibrant longer. Texture selections range from smooth surfaces to a wrinkled or matte finish, and rough textures designed for hiding surface imperfections.
Protects the environment
Unlike many liquid paints, powder coatings are compliant with environmental regulations. Liquid paints often contain solvents, which can contribute to air pollution and, in some cases, ozone depletion. Powder coatings are free of such pollutants.
Powder coatings are frequently a cost saving alternative to liquid paints with respect to labor costs, rework costs, material usage, waste disposal, and overall line efficiency. The advantage to manufacturers and the consumers is a coated part with a superior quality finish at a reasonable cost.
