Abstract: The present invention relates to a method for at least partly coating a metallic substrate, at least comprising at least partly coating the substrate with an autophoretically depositable coating composition (step (1)) and contacting, with an aqueous sol-gel composition, the substrate at least partly coated with the autophoretically deposited coating composition (step (2)), to an at least partly coated substrate obtainable by this method, and to the use of an aqueous sol-gel composition for aftertreating a coating composition applied to a substrate at least partly by autophoretic deposition, by contacting the autophoretically deposited coating composition with the aqueous sol-gel composition.

Abstract: The present invention relates to heat-curable compositions containing a mixture of reactive epoxy resins that contains, based on the mass of all epoxy resins, a) at least 10 wt % of an epoxy group-containing reaction product of epichlorohydrin with polypropylene glycol which has an epoxy equivalent weight of at least 250 g/eq, and b) at least 10 wt % of an epoxy group-containing reaction product of epichlorohydrin with a novolac resin which has an epoxy equivalent weight of at least 175 g/eq, and at least one latent hardener.

Abstract: The subject matter of the present Application is two-component compositions whose first component is a mixture of reactive epoxy resins and optionally further formulation constituents which contains, based on the mass of all epoxy resins, a) at least 10 wt % of an epoxy group-containing reaction product of epichlorohydrin with polypropylene glycol which has an epoxy equivalent weight of at least 250 g/eq, and b) at least 10 wt % of an epoxy group-containing reaction product of epichlorohydrin with a novolac resin which has an epoxy equivalent weight of at least 175 g/eq, and whose second component contains at least one thiol group-containing hardener for epoxy resins.
