Abstract: A PLASTIC BODY IS METALLIZED BY TREATING IT WITH A SOLVENT FOR THE SPECIFIC PLASTIC MATERIAL, FOLLOWED BY TREATMENT IN A SECOND SOLVENT WHICH IS MISCIBLE WITH THE FIRST SOLVENT BUT IS A NONSOLVENT FOR THE SPECIFIC MATERIAL. THE SOLVENT TREATED MATERIAL IS SEQUENTIALLY TREATED IN AN ACID CONDITIONER, AN ALKALINE CLEANING SOLUTION, AND NEUTRALIZED IN A DILUTE HYDROCHLORIC ACID SOLUTION PRIOR TO METALIZATION. EACH STEP MAY BE PRECEDED BY A RINSING STEP. THE METHOD OF THE INVENTION PROVIDES FIRMLY BONDED METAL FILMS TO POLYSULFONE SUBSTRATES. THE BONDED MATERIAL HAS PEEL STRENGTHS OF ABOUT 9 POUNDS PER INCH. THE METHOD OF THE INVENTION AS DESCRIBED HEREIN IS APPLICABLE TO THE MANUFACTURE OF ADDITIVE PRINTED CIRCUITS.
