Abstract: The present invention relates to organoalkoxysilane compositions which comprise at least one organoalkoxysilane S, and at least one anhydrous surfactant T, where the weight fraction of all of the organoalkoxysilanes S is 33% by weight, based on the weight of the organoalkoxysilane composition, and where the ratio of the weight sum of all of the organoalkoxysilanes S to the weight sum of all of the anhydrous surfactants T (S:T) has a value of from 5:1 to 1:2.

Abstract: Aqueous adhesion promoter compositions include at least one aminosilane and/or aminosiloxane and also at least one mercaptosilane. The adhesion promoter compositions are suitable more particularly as primers or adhesion-promoter undercoats for adhesives and sealants. They are especially suitable for the adhesive bonding of vehicle glazing. Exceptionally high adhesion has been found more particularly with glazing featuring applied silver prints.

Abstract: The present invention relates to aqueous two-component adhesion promoter compositions and also to their use in methods of adhesive bonding or sealing. Additionally it relates to packaging consisting of the two-component composition and also a pack having two chambers. The two-component adhesion promoter composition is composed of a first component K1 comprising at least one organoalkoxysilane S and at least one anhydrous surfactant T; and of a second component K2 comprising at least water and at least one acid, the acid being present in an amount such that, after components K1 and K2 have been mixed, the resulting mixture is acidic.

Abstract: The invention relates to the use of compositions containing a polyaldimine ALD of formula (I) as primers for adhesives or sealants. It turned out that said primers accelerate adhesion especially in winter weather without reducing the open time of the primer. Said accelerated adhesion is particularly important for fast-curing polyurethane adhesives or sealants.

Abstract: A multicomponent packaging is disclosed for an adhesive with at least one first and at least one second component. A first chamber is provided for accommodating the first component of the adhesive, the first chamber having an opening for removal of the adhesive. A second chamber is arranged within the first chamber for accommodating the second component of the adhesive. A sealing means is provided which, in the stored state of the multicomponent packaging, seals the opening in a fluid-tight manner.
