Abstract: Adhesion promoter compositions, containing: a) between 40 and 80 parts by weight of a binder composition, including i) 20-40 wt % of at least one silane-terminated polyurethane polymer STP, which can be obtained from at least one polyol P, aliphatic polyisocyanate I and organosilane OS1, ii) 4-20 wt % of at least one organosilane OS2 and/or organotitanate OT, iii) 0-3 wt % of at least one desiccant, iv) 40-80 wt % of solvent L1; b) between 0-30 parts by weight of industrial carbon black; c) between 0-1 parts by weight of UV marker; d) so much of solvent L2 that sum of a)-d) is 100 parts by weight; OS1 having secondary amino, mercapto or hydroxyl group on organic moiety and the at least one STP having been produced in absence of OS2, and the at least one P having an average OH functionality of at least 2 and equivalent weight of at most 500.

Abstract: The present invention relates to a adhesion promoter composition containing at least one aqueous dispersion of a solid epoxy resin; at least one polyamine; and at least one Compound V in free or hydrolytically releasable form which can enter into a condensation reaction with the polyamine. Adhesion promoter compositions according to the invention lead to an improvement in the adhesion under hot, humid conditions.

Abstract: The present invention relates to adhesion promoter compositions having at least one adhesion promoter substance, at least one black pigment and at least one luminescent substance. The adhesion promoter compositions can be located and identified easily by irradiation with UV light and analysis of the radiation which is emitted, and are therefore highly suited to use in automated operations, more particularly in the context of glazing a vehicle.
