ABSTRACT:
A novel method is provided for placing a covering layer of a cured organopolysiloxane composition onto the surface of a shaped article of a vinyl chloride resin in order to improve or mask the defective surface properties of articles made of vinyl chloride resins. The method comprises treating the surface of a vinyl chloride resin article with a low temperature plasma of gas, placing a covering layer of a curable organopolysiloxane composition on the so-treated surface of the articles and subjecting the article with the curable organopolysiloxane composition to curing conditions for the organopolysiloxane composition. The adhesive bonding between the vinyl chloride resin article and the layer of the cured organopolysiloxane composition, e.g. cured room temperature-vulcanizable silicone rubbers, is so strong and durable that very long service life of the article is ensured in a variety of application fields.
