Abstract

Plastic parts made from polyethylene, polypropylene or comparable materials are pretreated for painting by exposure to a fluorine-containing treatment gas. This treatment gas has an absolute pressure of from 333 to 400 mbar, contains 3 - 5 per cent by volume of fluorine and contains 10 - 16 per cent by volume of oxygen in addition to at least one other inert gas constituent. The exposure time of the treatment gas is from about 10 to 180 seconds. The reaction chamber is first evacuated to an absolute pressure of 200 mbar, and a gas mixture comprising 10% by volume of F2 and 90% by volume of N2 is then introduced until the absolute pressure has risen to 400 mbar. The amount of gas mixture comprising F2 and N2 flowing in per time unit is selected so that a pressure increase in the reaction chamber of between 100 mbar/min and 200 mbar/min is obtained.
