Aqueous polymer compositions and their use as coatings are disclosed. A composition includes at least one polyurethane (meth)acrylate A and at least one compound B having a molecular weight of below 1000 g/mol and having at least two ethylenically unsaturated double bonds per molecule. The polyurethane (meth)acrylates A include the following components: component A1 includes at least one polyisocyanate A1a and at least one diisocyanate A1b; component A2 includes at least one compound having at least one ethylenically unsaturated double bond, and at least one functional group F; component A3 includes at least one neutral polyol including at least one aliphatic, polymeric polyol A3a and at least one low molecular weight diol A3b; component A4 includes at least one compound having at least one ionic or ionizable group I' and at least one functional group F&#x2032;; and component A5 includes at least one poly-C-Calkylene ether.

Aqueous polymer compositions comprising polyurethane (meth)acrylates

The present invention relates to polyurethanes (A) being obtainable by reaction of (a) 15% to 70% by weight of di- or polyisocyanate comprising on average from 1 to 10 allophanate groups and on average from 1 to 10 C&#x2014;C double bonds per molecule, and optionally (b) 0% to 60% by weight of further di- or polyisocyanate, with (c) 5% to 50% by weight of compounds having at least two isocyanate-reactive groups, comprising at least one polycarbonate diol with a molecular weight from 500 to 3000 g/mol weight % ages being based on total polyurethane (A), with the proviso that the total is 100%.

Polyurethanes, dispersions thereof, their preparation and use

The present technology provides a heteroatom-containing polycarbonate polyfunctional-vinyl ether molecule of formula (I) and processes of preparing thereof. The present technology further provides a heteroatom-containing acrylate molecule of formula (II). An ink or coating formulation including an energy curable high reactivity heteroatom-containing polycarbonate polyfunctional-vinyl ether molecule of formula (I) or an energy curable high reactivity heteroatom-containing acrylate molecule of formula (II) is provided. 

Energy curable high reactivity multi vinylether or acrylate functional resins

A process for preparing a hyperbranched polycarbonate polyol includes reacting a polyfunctional alcohol and an ester or carbonate in the presence of a catalyst and then heating the reaction mixture under azeotropic reflux conditions to form an alcohol or water. The alcohol or water by-product is then removed from the reaction mixture, thereby pushing the reaction forward.

Preparation of hyperbranched polycarbonate polyols and their use

The invention relates to aqueous polyurethane dispersions that are curable with UV radiation. The polyurethanes are chain-extended with aromatic, cycloaliphatic or aliphatic diamine compound and cross-linked with aliphatic triamine compound. The polyurethanes are useful dispersions for coating various substrates. The use of the invented dispersions results in high hardness, very good flexibility and good chemical resistance in both clear coats and pigmented coatings before and after UV curing combined with very good adhesion to different substrates.
