Abstract
(EN)
ABSTRACT OF THE DISCLOSURE No-rinse compositions and a process are provided for inhibiting corrosion of ferrous or non-ferrous metal surfaces and for producing a surface to which synthetic resin coating compositions will adhere so that the resultant coatings have satisfactory impact and bending resistance, together with resistance to creeping corrosion between the metal and the dried resin coating.
