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 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.

Radiation curable coating composition based on chain-extended and cross-linked polyurethanes

The present invention relates to storage-stable water-emulsifiable polyurethane acrylates, to a process for preparation thereof and to the use thereof.

Process for preparing water-emulsifiable polyurethane acrylates

The present invention describes radiation-curable, water-dispersible polyurethane acrylates which feature good grain highlighting, their use, and the method for producing them.

Radiation-curing, water-dispersible polyurethane (meth)acrylates

Described herein is a process for preparing urethane (meth)acrylates. In a first step, a hydroxyalkyl (meth)acrylate is reacted with a lactone (B) in the presence of at least one zinc compound and/or bismuth compound (C) to produce a resulting zinc-containing product and/or a bismuth-containing product, and, in a further step, the zinc-containing product and/or the bismuth-containing product is reacted with at least one cycloaliphatic or asymmetric aliphatic diisocyanate (D).
