Participants

Reaction Steps

Suitable hardeners (C) for powder resins of the invention also include all those compounds known for this purpose, in particular anhydride hardeners such as, for example: phthalic anhydride, tetrahydrophthalic anhydride, 4-methyltetrahydrophthalic anhydride, hexahydrophthalic anhydride, 4-methylhexahydrophthalic anhydride, nadicmethyl anhydride (trivial name for isomers of methylendomethylenetetrahydrophthalic anhydride), chlorendic(HET) anhydride (3,4,5,6,7,7-hexachloro-3,6-endomethylenetetrahydrophthalic anhydride), pyromellitic dianhydride, benzophenonetetracarboxylic dianhydride, trimellitic anhydride, hardeners corresponding to the component (B) from DE 2 556 182 (which is herein incorporated by reference), dodecenylsuccinic anhydride, isooctenylsuccinic anhydride, etc., dicyandiamide which is produced, for example, under the trade name Dyhard® from SKW Trosberg, phenolic hardeners such as, for example, see Dow® hardeners D.E.H. 80, D.E.H. 82, D.E.H. 84, carboxylic acid salts of imidazole or imidazoline compounds, fusible, soluble adducts which are obtained by reaction of an epoxide compound with imidazole or imidazoline compounds or their carboxylic acid salts.
