We degrease and phosphate in house, so the powder goes onto clean, treated metal.
Oil, cutting fluid, shop dirt and fingerprints come off first. Powder laid over oil sits on the oil, not the metal. In the oven it pulls back from the spot and leaves a crater.
The clean steel is given a fine layer of phosphate crystals. It is not a paint. The phosphate reacts with the surface of the steel itself, so the layer grows out of the metal instead of sitting on top of it.
The powder bonds to the phosphate, not to bare steel. If the coat is ever scratched through to the metal, the phosphate under it helps slow rust creeping out under the coat from the scratch.
A powder coat holds only as well as the surface under it. On oily or untreated metal a coat can look right when it leaves the shop and still lift, blister or rust from underneath later.
A chemical treatment for clean steel. It turns the surface of the metal into a thin layer of phosphate crystals that the powder bonds to. It comes after degreasing and before the spray booth.
Oil and shop dirt come off in our degreasing. What has to come off before you bring a part in is anything that cannot go through an oven: rubber, plastic, wood, glass, bearings and seals.
