Abstract: Moisture curable silicone adhesives used for sealing joints and for the bonding of substrates such as PVC, concrete, mineral substrates, metals, glass, ceramic, wood, or painted surfaces are prepared from crosslinkable compositions containing both hydrophilic and hydrophobic fumed silicas in a mass ratio of 1:10 to 10:1.

Abstract: Room temperature, moisture curable, transparent, and non-yellowing polymer blends contain at least one alkoxysilyl-terminated polymer bearing an end group -A-(CH2)m—SiR1a—(OR2)3-a where A is a divalent linker group, contain a silica filler of high surface area as the sole filler, and is catalyzed by a catalyst which is free or substantially free of amine groups.

Abstract: Moisture curable alkoxysilyl-functional polymers crosslinkable to elastomers having improved recovery properties are prepared by incorporating in the curable composition, both an aminoalkylalkoxysilane and an epoxyalkylalkoxysilane.

Abstract: The invention provides a method of increasing the elasticity of moisture-cured elastomers, which comprises adding to alkoxy-cross linking one-component compositions comprising an alkoxysilane-terminated polymer (A) containing end groups of the formula (1) -A-Si(R)a(CH3)3-a??(1) a silane (B), of the general formula (2) X—CH2—Si(R)2(CH3)??(2) where A is a divalent hydrocarbon radical, R is a methoxy or ethoxy group, X is a group R?O—, R?NH—, R?—O—CO—NH, R?—NH—CO—NH— or halogen, R? is hydrogen, an optionally halogen-substituted C1-18 hydrocarbon radical or a radical R?—O—CO— or R?—NH—CO, R? is an optionally halogen-substituted C1-8 hydrocarbon radical, and a is 1, 2 or 3.
