ABSTRACT:
Certain quaternary salts of di- and/or tri-(alkanol)-amines, which salts are soluble in the aqueous bath employed, are used as conditioners for pretreating nonmetallic surfaces of moldings prior to their activation for subsequent chemical metallization.
Outstandingly uniform and strongly adhering metal coatings are obtained in this manner.
