Abstract
A method of adhering a substantially cured or fully cured silicone based material to a substrate surface is provided. The silicone based material is obtained by curing a condensation curable composition. The condensation curable composition comprises: (I) at least one condensation curable silyl terminated polymer having at least one hydrolysable and/or hydroxyl functional group(s) per molecule; (II) a cross-linker selected from the group of silanes having at least two hydrolysable groups per molecule; and/or silyl functional molecules having at least two silyl groups, each silyl group containing at least one hydrolysable group; and (III) a condensation catalyst selected from the group of titanates and zirconates. The method includes applying a reactive interlayer to the substrate surface and applying pressure to sandwich the reactive interlayer between a surface of the silicone based material and the substrate surface, thereby causing chemical bonding of the silicone based material to the substrate.
