Metal Guard 700 is an emulsion rust preventative offering outstanding corrosion protection to blackened, phosphate, and bare metal surfaces during storage and transportation. After water evaporation, this emulsion leaves an extremely thin dry film. Metal Guard 700 is normally used as received but may be diluted with water, in special applications. Since Metal Guard 700 is a water emulsion, parts can be processed through it without pre-drying. Some care should be exercised, however, to prevent too great a carryover of water which would, in time, dilute the emulsion resulting in a thinner deposit with lower protective quality. Metal Guard 700 coating will air-dry in a relatively short time. The drying period can be shortened by force drying with warm air or in heated spin dryers. If it becomes necessary to reprocess the parts, the coating may be removed in a hot alkaline cleaner or vapor degreaser.
