RIE Coatings will degrease your parts if they arrive to us with oils or other contaminants on them. This is a critical step that ensures the substrate is clean when coatings are applied. RIE Coatings utilizes a variety of substrate pretreatment processes. Zinc phosphate, manganese phosphate, and abrasive blasting are all used at RIE Coatings and prescribed on an individual basis. Pretreatment is the single most important step to ensure proper coating adhesion and ultimately affects the protection and performance of the parts being processed.
