Patent ID: 8702899

Claim:
A pulverulent composition, comprising: a sieved dry blend of particles of the following components or particles of homogeneous mixtures of combinations of some of the following components: A) at least one curative comprising at least one uretdione group; B) at least one quaternary ammonium salt or phosphonium salt; C) at least one epoxide or acetylacetonate; D) at least one monomeric, oligomeric, or polymeric mono or polyalcohol; E) optionally, at least one acid in monomeric or polymeric form; and F) optionally, at least one auxiliary, additive, and/or further catalyst; wherein an isocyanate content of the pulverulent composition decreases by not more than 25% upon storage for four weeks at 25° C., a maximum particle size of the seived particles is 200 μm, components B) and C) are not in a same homogeneous component mixture, and a melting point of the composition is greater than 40° C.
