Abstract

A typical compsn. contains 10 pts. ethylglycol, 60 pts. dichloromethane, 30 pts. carbolic acid, 10 pts. nonylphenol 9M OE condensate, 5 pts. water, 1 pt. Na chromate, 1 pt. Na metasilicate and 1 pt. polyvinylpyrrolidone. The compsn. may be used on metal assemblies comprising combinations of Al, Mg, steel, Cu and Pb.
