Black oxide is a conversion coating formed by a chemical reaction produced when parts are immersed in the alkaline aqueous salt solution operated at approximately 285 degrees F. The reaction between the iron of the ferrous alloy and the hot oxide bath produces a magnitite (Fe3 O4) on the actual surface of the part.
Red oxide primer is a specially formulated coating used as a base coat for ferrous metals. Red-oxide primer serves a similar purpose to interior wall primers in that it prepares your metal for a topcoat, but it also gives iron and steel surfaces a layer of protection.Working with red oxide primer is not difficult, but it helps to be aware of some safety precautions and application tips.hen applying red oxide primer, use a brush or a short pile roller. Thinning is not normally required if applying with a brush or roller. If you use an airless sprayer to apply red oxide primer, thin the primer 10 to 15 percent by volume with acetone, xylene or synthetic reducer.
