A highly concentrated water base corrosion inhibitor for ferrous metals. It forms a clear solution in water and leaves a uniform rust inhibiting film on parts which will provide up to 6 months indoor storage protection on in-process and finished parts. PRO-TEC PLUS can be added to existing synthetic, semi-synthetic, and soluble oil systems to provide added rust protection. PRO-TEC PLUS inhibiting film is paintable in many applications with no adhesion problems. (Adhesion testing recommended.) It is compatible with Loctite PMS-10E Impregnation Resin.
