摘要:
Disclosed are bismuth compound-containing electrodeposition paints comprising: A) at least one self-crosslinking and/or external crosslinking bonding agent which containing (potentially) cationic or anionic groups and reactive functional groups which can thermally react with i) themselves or complementary reactive functional groups contained in the self-crosslinking bonding agent, or ii) complementary reactive functional groups contained in crosslinking agents (B) if an external crosslinking bonding agent is used; B) at least one optional crosslinking agent containing the complementary reactive functional groups; and C) at least one bismuth compound.

摘要:
The present invention relates to aqueous dispersions of binders for cationic electrodeposition coatings, containing amine-modified hydroxyfunctional epoxy resins as a binder as well as at least one fully blocked polyisocyanate, which is at least partially blocked with 2,2-dimethyl-1,3-dioxolane-4-methanol, as a cross-linking agent and use of corresponding cationic electrodeposition coatings for the production of coatings and the use of cross-linking agents on the basis of polyisocyanates blocked with 2,2-dimethyl-1,3-dioxolane-4-methanol in aqueous dispersions of binders.
摘要:
The invention relates to a method for coating a metal or plastic substrate, which is pre-coated if necessary, by (a) application to the substrate of an aqueous coating composition (W), the components of which are free of or substantially free of blocked isocyanate groups, which contains an aqueous dispersion of an epoxy-amine adduct, and which either does not contain crosslinking agents or contains one or a plurality of unblocked polyisocyanates as crosslinking agents, (b) application of one or a plurality of further coating compositions if necessary, and (c) curing of the coating composition (W) and, if necessary, the further coating compositions(s) at temperatures below 90 °C.
摘要:
The invention relates to electrodeposition paint compositions containing catalytically active core/shell particles. Said electrodeposition paint compositions can be particularly used in cathodic electrodeposition coating processes for painting automobile bodies or parts thereof.
摘要:
The invention relates to a method for producing a pigment paste by mixing at least one pigment composed of solid particles with a grinding resin in the presence of water and/or an organic liquid, characterized in that the grinding resin consists of or comprises a dispersion of core-shell particles in an epoxide prepolymer which is liquid at 20°C and the core-shell particles have a silicone core and a polymer shell. The invention also relates to an aqueous electrocoat material, to its use, to a method for cataphoretic electrocoating and to a coated article.
