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.

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.
