Abstract: A composition and composite article have improved adherence with an addition-curable material. The composition and therefore the composite article, which includes at least one substrate formed from the composition, include a resin and an additive that is incorporated into the resin. The resin is organic and polymeric and free of ethylenically unsaturated and silicon hydride functional groups. The additive is selected from the group of a fluorine-substituted organopolysiloxane, an amino-functional organopolysiloxane, an unsaturated carboxylic acid or carboxylic acid salt, and combinations thereof. Further, the additive includes a hydrosilylation reactive group present at a surface of the substrate for reaction with the addition-curable material. This improves adherence of the substrate with the addition-curable material. The substrate and the addition-curable material bond together to make the composition article.
