Polychloroprene dispersions containing particles of urea derivatives having a particle size in the range of 10 to 400 nm, which can be used in adhesive compositions. The adhesive compositions can be used to provide substrates containing adhesive layers obtained from the compositions.

Dispersions

Novel sizing compositions, their preparation and use. The compositions contain water-dispersible and/or water-soluble and alkylamine-blocked polyisocyanates, film-forming resins, coupling agents and lubricants. The isocyanates are synthesized from at least one polyisocyanate, at least one ionic and/or potentially ionic and/or nonionic compound, and at least one blocking agent which is at least 20% by weight aralkylamines.

Sizing composition

Blocked polyisocyanates and one-component stoving systems containing these blocked polyisocyanates, and the preparation thereof and their use for the preparation of lacquers, paints, adhesives and elastomers, wherein blocked polyisocyanates are prepared by reacting polyisocyanates with secondary amines corresponding to the formula wherein wherein R&#x2013;Rcan be identical or different and independently of one another denote C&#x2013;-alkyl and/or C&#x2013;C-cycloalkyl, Rdenotes hydrogen or C&#x2013;-alkyl or C&#x2013;C-cycloalkyl.

Blocked polyisocyanates

Blocked polyisocyanates and one-component stoving systems containing these blocked polyisocyanates, and the preparation thereof and their use for the preparation of lacquers, paints, adhesives and elastomers. The blocked polyisocyanates are derived from polyisocyanates reacted with secondary amines and cationic, anionic and/or nonionic hydrophilizing agents such that they are incorporated into the polyisocyanate at a ratio of fromto, wherein the blocking agents correspond to the formula  

The present invention relates to aqueous self-crosslinking PU dispersions and to coatings prepared from them.

Self-crosslinking PU dispersions

The present invention relates to novel one-component polyurethane systems including one or more organic and/or inorganic compounds of vanadium in which the vanadium has an oxidation state of at least +4, to their preparation and use for preparing paints, inks and adhesives.

Polyurethane coating systems

The invention relates to aqueous and/or water-dilutable blocked polyisocyanates, their preparation and use in optionally self-crosslinking one-component systems.

Aqueous coating compositions based on polyurethane dispersions which cure under the influence of high-energy radiation, to a process for preparing them and to their use. The coating compositions contain a polyisocyanate, a polyurethane containing free-radically polymerizable groups, and an initiator which is capable of initiating a free-radical polymerization.

Radiation-curing coating compositions

The invention relates to a powdered thickener preparation based on polyurethane, which can be incorporated particularly well into water-based paints and lacquers and into other aqueous systems, and to their use as rheological additives for thickening preferably aqueous systems.

Powdered thickener preparations based on polyurethane and their use for thickening aqueous systems

The invention relates to polyurethane-polyurea dispersions, also called PU dispersion, which contain aralkylamine-blocked isocyanate groups, and to their preparation and use. This blocking agent ahs a significantly lower deblocking temperature as compared with the prior art. Coatings produced from this dispersion have high hydrolysis resistances. The arylamine-blocked isocyanate groups are composed of polyisocyanates, polymeric polyols having average molar weights of 400 to 6000, at least one blocking agent, and either or both of nonionically hydrophilicizing compounds or compounds having at least one ionic or potentially ionic group.

Polyurethane-polyurea dispersions

The invention relates to aqueous and/or water-dilutable polyisocyanate crosslinkers blocked with diisopropylamine, to their preparation and use in one-component baking lacquers, for example as fillers in automotive lacquering.
