Abstract
Surfaces of articles formed from (1) normally solid polymers of aliphatic mono-1-olefins and (2) elastomeric and resinous polymers of conjugated dienes and vinyl-substituted aromatic compounds are conditioned by contact with a fluorine-containing gas under conditions and for a period of time sufficient to render the surface receptive to adhesives, coatings, paints, inks, decorations, and the like. The fluorine-containing gas can be pure or admixed with up to about 99 volume percent inert gas.
Claims10
A process for treating a polymeric surface formed from (1) normally solid polymers of aliphatic mono-1-olefins and (2) elastomeric and resinous copolymers of conjugated dienes and vinyl-substituted aromatic compounds which comprises contacting said surface with a fluorine-containing gas under conditions and for a period of time sufficient to render said surface water-wettable and receptive to adherence of a second material selected from adhesives, coatings, paints, inks, decorations, and the like, and then contacting said surface with said second material under conditions which cause said second material to adhere to said fluorinated surface.
A process for coating a polymeric surface formed from normally solid polymers of aliphatic mono-1-olefins which comprises contacting said surface with a fluorine-containing gas under conditions and for a period of time sufficient to render said surface water-wettable and receptive to a polysulfide coating, coating said treated surface with a liquid organic polysulfide, and curing said polysulfide coating by heating at an elevated temperature sufficient to form a polysulfide coating that adheres tenaciously to the fluorine-treated polymeric surface.
