Norchem Os 238  Osphos (Metal Treatment)

Norchem OS 238 Osphos is an acidic based metal treatment and rust preventive for treating clean and lightly rusted steel and metal surfaces prior to painting. When applied, Osphos will chemically impart and change the applied surface into a phosphate film which acts as a rust preventive and paint-base coat for better paint adhesion. Osphos may also be effectively used for cleaning rust stains from painted and unpainted metal parts and surfaces.
