A process for producing a water-emulsifiable polyisocyanate formulation, in which, in a first process step,

Water-emulsifiable isocyanates with improved properties

A mixture of water-emulsifiable isocyanates is described. The mixture contains (A) at least one polyisocyanate (a), (B) at least one emulsifier obtained by reacting at least one polyisocyanate with at least one polyether alcohol having a molecular weight of less than 400 g/mol, (C) at least one emulsifier obtained by reacting at least one polyisocyanate with at least one polyether alcohol having a molecular weight of greater than 450 g/mol, and (D) optionally at least one emulsifier obtained by reacting a polyisocyanate with at least one compound (d) having at least one hydrophilic, non-isocyanate-reactive group and precisely one isocyanate-reactive group (group D2). The weight ratio of component (B) to component (C) in the mixture is from 30:70 to 70:30, preferably from 40:60 to 60:40.

The present invention relates to the use of two-component coating compositions comprising isocyanurates of pentamethylene diisocyanate and NCO group reactive compounds with rapid curing and good chemical resistance at temperatures to 80&#xb0; C.

Two-component coating compounds

Binder systems for high-gloss coatings and processes for producing them are provided, where the binder systems are prepared by preparing an aqueous polymer dispersion by radically initiated aqueous emulsion polymerization using defined first and second polymerization stages wherein the weight ratio of the sum of the total amounts of first polymerization stage monomers A1 to C1 (total monomer amount 1) to the sum of the total amounts of second polymerization stage monomers A2 to C2 (total monomer amount 2) is in the range 5:95 to 70:30, the amount of chain transfer agent in the second polymerization stage is selected such that the resulting overall polymer has a weight-average molecular weight of &#x2265;15 000 and &#x2264;50 000 g/mol, and the amount of the dispersing assistant is &#x2264;3.0 wt %, based on the sum of total monomer amount 1 and total monomer amount 2 (total monomer amount).

The present invention describes new crosslinkers for coating compositions, their preparation, and their use.

Crosslinkers for coating compounds

The present invention relates to improved water-dispersible polyisocyanates with enhanced gloss, more particularly for two-component polyurethane coating materials.

Water-dispersible polyisocyanates

The invention relates to new, water-emulsifiable isocyanates, to a process for preparing water-emulsifiable isocyanates, and to the use thereof.

Water-emulsifiable isocyanates for coatings having an improved gloss

The invention relates to a process for the preparation of water-emulsifiable isocyanates and to their use.

Water-emulsible isocyanates having improved gloss

The present invention relates to new, urethane-group-containing polyisocyanates based on aliphatic and/or cycloaliphatic diisocyanates, and to their use.

High-functionality polyisocyanates containing urethane groups

The present invention relates to coating compositions repairable by introduction of energy and comprising defined fatty acid esters, to coatings obtained therewith and repairable by introduction of energy, to methods of producing them, and to their use.

Coatings repairable by introduction of energy

The present invention relates to a novel process for preparing polyisocyanates having isocyanurate groups by a partial trimerization of (cyclo)aliphatic diisocyanates in the presence of at least one trimerization catalyst from the group of ammonium salts of lactames and to the use of the thus obtainable polyisocyanates having isocyanurate groups as a polyisocyanate component in polyurethane coatings.
