Described herein is an aqueous resin dispersion (AD) including a resin component (R) including at least one di- and/or polyfunctional monomeric primary and/or secondary amine (M) and polyfunctional polymeric organic amines having primary and/or secondary amino groups. Also described herein is an aqueous two-component coating composition including the resin dispersion.

Aqueous resin dispersion and aqueous coating composition containing said resin dispersion

Provided herein is a coating composition curable by condensation and/or addition reactions and including (A) at least one polymer as binder, (B) at least one crosslinking agent that can be reacted by condensation and/or addition reaction with component (A), and (C) at least one specific complex as catalyst. Also provided herein is a use of the complex for catalyzing the curing of coating compositions curable by condensation and/or addition reaction.

Condensation reaction and/or addition reaction curable coating composition

The invention relates to a coating that is produced from a thermally curable, aqueous coating material on an organic basis, and that contains colloidally dispersed metallic bismuth. The invention further relates to the use thereof as anti-corrosive coating on metal substrates.

Coating that contains a colloidally dispersed metallic bismuth

The invention relates to the use of a water-soluble polyvinyl alcohol (co)polymer or a mixture of polyvinyl alcohol (co)polymers as additives in aqueous electrodeposition baths, to electrodeposition baths comprising a polyvinyl alcohol (co)polymer, and to a method of coating an electrically conductive substrate.

Electrodeposition bath with water-soluble polyvinyl alcohol (co) polymers

An agent for the single-stage full blocking of polyisocyanates comprises or consists of an alcohol mixture A) comprising a) furfuryl alcohol or substituted furfuryl alcohols in an amount corresponding to from 60 to 90, in particular from 65 to 85, mol % of hydroxyl groups and b) at least one monoalcohol in an amount corresponding to at least 2 mol % of hydroxyl groups, based in each case on the total amount of hydroxyl groups in components a) and b). In addition, the alcohol mixture A) may also include at least one aliphatic polyol c) of low molecular mass with a functionality of three and/or more in an amount corresponding to at least 5 mol % of hydroxyl groups, based on the total amount of hydroxyl groups in components a), b) and c). In this case component b) can have a molecular weight of <163 g/mol. In a single stage, the blocking agent yields fully blocked polyisocyanates having a low crystallization tendency that are suitable as crosslinking agents in coating compositions, especially in cathodically depositable electrodeposition coating materials.
