A composition of matter including (i) an epoxy resin and (ii) a cross-linking agent therefor, said cross-linking agent being the reaction product of trimellitic anhydride with a diol, and wherein such reaction the molar ratio anhydride/diol is not in excess of 2, is a useful binder for coating compositions, notably the powder paints.

Epoxy resin and noval cross-linking agent therefor

A saturated, cross-linking binder composition for use in powder coatings is disclosed. The composition comprises at least two saturated cross-linking resins and a cross-linking agent in which the resins exhibit different reactivities with respect to the cross-linking agent.

Binder compositions for powder coatings

A saturated cross-linkable binder composition adapted for preparing coatings having a non-glossy surface is disclosed which comprises:

Cross-linkable saturated powderous compositions and powderous painting

Binder compositions for powder coatings from mixed saturated resins

Curable, saturated polyester resins and epoxy resin cross-linking agents therefor, in association with an at least divalent metal oxide and a cross-linking catalyst, are useful binders for mechanically improved powder paints, e.g., those typically applied to metallic substrates by electrostatic deposition or fluidized bed spraying.

Cross-linkable, saturated polyester coating compositions

Curable, saturated polyester resins and cross-linking agents therefor, in association with an at least divalent metal oxide, are useful binders for the powder paints, e.g., those typically applied by electrostatic deposition or fluidized bed spraying.
