Described herein are aqueous electrocoating materials including a silane-containing crosslinking agent, a process to produce an electrocoated substrate, an at least partly coated substrate obtained from said process, as well as a component including said at least partly coated substrate.

Aqueous electrocoating materials comprising a silane-containing crosslinker

Described herein is a specific aqueous two-component coating composition including an epoxy resin-based paint base component (1), and a polyamine-based curing component (2), where the paint base component (1) includes at least one aqueous dispersion of at least one pigment (P) and/or filler (F) in at least one epoxy resin (E), where the at least one epoxy resin (E) has (i) a maximum sedimentation rate of not more than 17,500 micrometers per hour and a glass transition temperature of less than 0° C., or (ii) a maximum sedimentation rate of at least 12,500 micrometers per hour and a glass transition temperature of at least 0° C.

Aqueous coating composition comprising an epoxy resin-based paint base component

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 present invention relates to aqueous binder dispersions for cationic electrocoat materials, comprising as binders amine-modified, hydroxy-functional epoxy resins and comprising as crosslinker at least one fully blocked polyisocyanate blocked at least partly with 2,2-dimethyl-1,3-dioxolane-4-methanol, and also to the use of such cationic electrocoat materials for producing coating systems and to the use of crosslinkers based on polyisocyanates blocked with 2,2-dimethyl-1,3-dioxolane-4-methanol in aqueous binder dispersions.

Aqueous binder dispersions intended for cathodic electrocoat materials and comprising a crosslinker based on 2,2-dimethyl-1,3-dioxolane-4-methanol-blocked polyisocyanates

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.
