    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.

    Abstract: A condensation cure organosiloxane composition is disclosed. The composition may be used as an electrically insulating sealant and/or adhesive. The composition is a silicone elastomer composition comprising: (a) a polydiorganosiloxane having at least two —OH or hydrolysable groups per molecule; (b) a cross-linker which will cross-link polydiorganosiloxane (a); (c) a filler component comprising (i) a maximum of 25% by weight of the composition of calcium carbonate and/or silica, and (ii) an amount of one or more fibrous fillers selected from mineral fibers, bulk fibers, refractory fibers, basalt fibers, or mixtures thereof; (d) a condensation curing catalyst; and optionally (e) one or more additives. Upon cure, the composition provides a silicone elastomer having a volume resistivity which is ≥2×1015 Ω·cm.

    Abstract: Improvements in or relating to transparent units (such as glazing units, which may also be referred to as insulating glass units) and their methods of manufacture are disclosed. Each transparent unit comprises first and second panes of transparent material each having an outwardly facing side and an inwardly facing side. Each inwardly facing side is at least partially coated with a reactive interlayer made by the application of a reactive interlayer coating composition. The inwardly facing side of the first and second panes of transparent material are spaced apart partially or totally by a transparent spacer made of a pre-cured condensation curable material or a substantially pre-cured condensation curable material adhered to the inwardly facing side of the first and second panes of transparent material by way of the reactive interlayers. In various embodiments, the pre-cured condensation curable material is a silicone based material.
