ABSTRACT:
The invention provides a process and composition for preparing steel surfaces for adhesive bonding. The process involves contacting the steel article with an etchant composition containing phosphoric acid and a liquid polyhydric alcohol such as propylene glycol, diethylene glycol or glycerine. The process produces steel surfaces, which when adhesively bonded yield joints much stronger than those obtained by abrasive blasting, and comparable to those obtained by use of phosphoric acid-ethanol etchant compositions without the hazards of the latter.
