Abstract:
The present invention discloses a two-component adhesion-promoter composition for surface pretreatment, comprising two components, the first component, K1, comprising at least one hydrolyzable adhesion promoter substance A which is selected from the group comprising organosilicon compounds, organotitanium compounds, organozirconium compounds, and mixtures thereof; and the second component, K2, comprising at least one compound B which reacts with the adhesion promoter substance A or triggers or catalyzes condensation of the adhesion promoter substance A, and the first and the second components in the unopened state being present in two compartments (1, 2) separated from one another by at least one dividing wall (3).Additionally disclosed are the use of a pack (5) having two compartments (1, 2) which are separated from one another by a dividing wall, and a package (6) composed of a pack (5) and of a two-component adhesion promoter composition, in the compartments (1, 2) separated from one another by a dividing wall 3.

Abstract:
Novel undercoats for use on porous bases such as, for example, concrete are disclosed. Said undercoats contain or comprise at least one epoxy resin, at least one latent hardener and at least one solvent. The above are characterize in being easy to produce, contain no isocyanate groups and form a good ageing-resistant adhesion, in particular, with single component isocyanate-free sealants, cross-linked by means of silane groups.
Abstract:
The invention relates to a primer composition, comprising at least one polyurethane prepolymer (A) with isocyanate terminal groups, at least one aliphatic polyisocyanate (B), at least one aromatic polyisocyanate (C) and at least one reaction product (D), which may be obtained from at least one epoxysilane and at least one aminosilane or from at least one epoxysilane and at least one mercaptosilane. The invention relates to the use of the primer composition as primer for adhesives, sealants and floor coatings.
