Abstract
A method of surface treating elastomer surfaces comprises applying thereto a 4-substituted-1,2,4-triazoline-3,5-dione preferably in solution. The treatment improves adhesion using normal elastomer adhesives, improves resistance to peeling with flexible paints and reduces the surface tack of the elastomer. The method is advantageous over prior art chlorination and halogen donor techniques particularly in that the triazoline diones are relatively non-corrosive and non-toxic.
Claims10
A method of treating a surface of a non-polar unsaturated elastomer to improve the adhesion characteristics thereof which method comprises applying to the surface of the elastomer a 4-substituted-1,2,4-triazoline-3,5-dione.
A method of adhering a surface of a non-polar unsaturated elastomer to a substrate comprising treating the surface of the elastomer by applying thereto a 4-substituted-1,2,4-triazoline-3,5-dione, applying an adhesive to the treated elastomer surface, the substrate or both treated elastomer surface and substrate and adhering the elastomer surface and substrate together.
