Abstract:
Layers of siloxane tackifying resins that do not contain siloxane fluids, gums or polymers act as adhesion promotion agents. Articles include a substrate layer, a non-tacky siloxane tackifying resin adhesion promotion layer disposed on the surface of the substrate layer, and a crosslinked siloxane layer in contact with the adhesion promotion layer. The crosslinked siloxane layer is not an adhesive layer. The adhesion of the crosslinked siloxane layer to the substrate is greater than the adhesion without the non-tacky siloxane tackifying adhesion promotion layer.
