The Pretreatment Process

Stage One is applying a multi metal alkaline cleaner that removes most of the loose dirt and oils.

Stage Two is a clean hot water rinse to remove all of the remaining dirt, oil and any excessive alkaline build up.

Stage Three is an Iron Phosphate wash. The Iron Phosphate creates a coating on the material to help promote adhesion.

Stage Four is a cold water rinse to remove any existing Iron Phosphate and to stop the reaction process.

Stage Five is a non-chrome sealer that is applied if the customer requests it. The purpose of the non-chrome sealer is to remove any unreactive phosphates, cover bare spots, stop flash rusting and to extend the life of the material from salt spray.
