Powder coating is the technique of applying dry paint to a part. In powder coating, the powdered paint may be applied by either of two techniques. The item is lowered into a fluidised bed of the powder, which may or may not be electrostatically charged, or the powdered paint is electrostatically charged and sprayed onto the part.The part is then placed in an oven and the powder particles melt and coalesce to form a continuous film. Powder coating produces a high specification coating which is relatively hard, abrasion resistant (depending on the specification) and tough. The basis of any good coating is preparation.
