Abstract: This invention relates to a crosslinking component for binder resins which is especially suitable to be used together with epoxy-group containing binders and/or (poly)isocyanates such as blocked (poly)isocyanates and which comprises at least two blocked isocyanate groups per molecule of the crosslinking component whereby at least one of the at least two blocked isocyanate groups is a group according to structural unit (I), wherein the ratio of structural units of formula (II), if present, to structural units of formula (I) is 0.40 or below. The cross-linking component may also be self-cross-linkable. The present invention further relates to a coating composition, e.g. a one-component coating composition comprising the crosslinking component and a method of its manufacture.

Abstract: A coating process for electrical steel sheets using a varnish composition includes: a) applying a varnish composition coating layer onto the surface of an electrical steel sheet. The varnish composition comprises (A) about 1 to about 95 wt % of a resin comprising nucleophilic groups chosen from OH, NHR, SH, carboxylate and CH-acidic groups, and electrophilic groups which can react with the nucleophilic groups, wherein the resin is capable of transacylation in its main chain and/or side chain(s), (B) about 5 to about 75 wt % of an organic solvent and/or water, (C) 0 to about 40 wt % of a resin different from (A), (D) 0 to about 10 wt % of a customary additive, (E) 0 to about 40 wt % of a pigment, filler and/or nano-scaled particle and/or monomeric and/or polymeric element-organic compound, wherein the wt % is based on the total weight of the varnish composition; b) curing the applied coating layer.

Abstract: The invention provides a coating process for electrical steel sheet using a varnish composition, comprising the steps of a) applying at least one coating layer of a varnish composition onto the surface of the electrical steel sheet wherein the varnish composition comprises (A) 1 to 95 wt % of at least one resin comprising nucleophilic groups selected from the group consisting of OH, NHR, SH, carboxylate and CH-acidic groups, and electrophilic groups which can react with the above mentioned nucleophilic groups, wherein the resin is capable of transacylation in its main chain and/or side chain(s), (B) 5 to 75 wt % of at least one organic solvent and/or water, (C) 0 to 40 wt % of at least one resin different from (A), (D) 0 to 10 wt % of at least one customary additive, (E) 0 to 40 wt % of at least one pigment, filler and/or nano-scaled particle and/or monomeric and/or polymeric element-organic compound, wherein the wt % based on the total weight of the varnish composition. b) curing the applied at least one coating layer. Reduced energy consumption while curing the coating and reduced or no formaldehyde generation upon curing can be provided.
