Identifying soils to avoid pretreatment failures
If you can't identify the soils on the substrates you powder coat, you can't properly get rid of them and provide a good clean surface for powder coating application. As a result, you'll get surface defects, poor adhesion, and eventually, field failures.
Virtually any product with a coated surface needs some form of pretreatment. With powder as a topcoat, pretreatment should leave the raw part as clean as possible. A powder's performance is based directly on the pretreatment it receives. Needed testing re
