MANGANESE PHOSPHATE Chemical compatibility with O-rings, rubbers, & plastics

Manganese phosphate is a gray or black crystalline solid with the chemical formula Mn₃(PO₄)₂, used primarily in the surface treatment of metals. It is employed in the process of manganese phosphating, which involves coating metal surfaces with a manganese phosphate layer to improve corrosion resistance, lubrication, and wear resistance. Manganese phosphate coatings are commonly used in automotive, aerospace, and military applications. Despite its utility, manganese phosphate can cause skin, eye, and respiratory irritation if not handled properly. Proper handling, storage, and safety measures, including the use of personal protective equipment, are essential to ensure safe usage and prevent exposure.
