Metal Guard 200 is an outstanding oil-based water displacing, non-staining rust preventive that will rapidly separate water displaced from metal surfaces following machining or cleaning operations. This product is designed to apply an ultra-thin highly protective film on ferrous or non-ferrous metals. These films may be applied to the substrate by dipping, spraying or brushing and prevent atmospheric corrosion even under conditions of high humidity.
Metal Guard 200 is recommended for use as a final dip for black oxide and zinc or manganese phosphate coatings. Parts may be dipped while they are still wet from final rinse stage since the displaced water rapidly settles to the bottom of the dip tank where it is periodically drawn off.
Metal Guard 200 produces a protective film of approximately 0.04 mils thickness when used as is. In applications where minimal protection is required, this product may be diluted with mineral spirits, kerosene or naphthenic oils of very low viscosity.
