Abstract:
The present invention relates to the adhesional pretreatment of plastics surface prior to their metallization by chemical or electrochemical methods and may be used in those industrial fields where decorative or functional metalic coatings on top of the plastic surfaces are needed. The purpose of the proposed invention is a high-quality adhesional pretreatment of plastic surface prior to metallization. The purpose is achieved by treating the plastic before to etch it 5-15 min at 50-70° C. in the alcaline permanganic solution containing 1-3M NaOH and 0.1-0.5 M permanganate ions and acidic permanganic etching solution additionally contains 0.5-8.0 M of copper nitrate and the etching is performed at room temperature during 5-60 min.

Claim (Index 1):
A method for adhesional pretreatment of plastic surfaces prior to their metallization comprising its etching with acidic permanganic solution, characterized in that the plastic before etching is maintained 5-15 minutes at 50-70\u00b0 C. in an alcaline permanganic solution containing 1-3 M NaOH and 0.1-0.5 permanganate ions while 0.5-8.0 M of copper nitrate are additionally introduced into acidic permanganic etching solution and the etching is performed at room temperature for 5-60 minutes.
