Powder coating is increasingly accepted as the preferred finishing process for the future for many applications.
Increasingly stringent environmental regulations, rising costs in all areas, and demands by consumers for better quality and more durable products are among the challenges facing today’s finisher. Powder coating provides a solution to these challenges and others.
Powder coating is the technique of applying statically charged dry paint to a part which is then heated in an oven to melt and cure the paint. The final cured coating is the same as a 2-pack wet paint. The powdered paint is normally applied by using a powder feed system and gun to electro statically charge and spray the powder onto the part. For some uses, such as pipes, the part being coated is dipped into a fluidised bed of powder. The part is then placed in a curing oven. During the curing process a chemical cross-linking reaction is triggered and it is this chemical reaction which gives the powder coating many of its desirable properties.
Powder Coating gives a dry, clean, durable coating. It is environmentally friendly. Unlike liquid finishing were solvents are used, powder coatings do not release Volatile Organic Compounds into the atmosphere. Unlike wet spraying, in many cases the over sprayed powder can be recycled for re-use.
Powder coating can produce much thicker coating than conventional liquid coatings without running or sagging. Additionally a wide range of effects are easily accomplished which would be impossible to achieve with other coating processes.
Capital equipment and operating costs for powder coating lines are generally less than for conventional wet spray lines.
