Powder Coating (1)
Powder coating is the process of coating a surface in which a powder material is applied using an electrostatic & compressed air method. The applied powder is then heated until it melts, after which it 'flows' to form a smooth film.

This dries to a firm, durable finish. It is very resistant to scratches, cracking, peeling, UV rays and rust. Powder coatings are a cost saving alternative to liquid paints with respect to energy savings, labour costs, re-work costs, material usage, waste disposal, and overall line efficiency.

Due to the oven reaching a temperature of 180C plastic items such as bearings should be removed prior to work being carried out

The advantage is a coated part with a superior quality finish at a reasonable cost.

WE STOCK OVER 100 RAL COLOURS

The Entire Powder Coating Process Involves Several Steps:
 

† A blasting, stripping and/or solvent cleaning step to ensure the substrate is free of any oils, dirt, rust, mill scale, etc;
 

† A pre-treatment step (an important step not done by all coaters) during which the product is treated with a pre-treatment chemical or conversion coating, usually phosphate or zinc based, to further protect it and improve the surface for powder adherence.
 

† 'Cooking' the product in the oven, generally at 180C, for 15-20 minutes in a pre-heated oven.
