Abstract
The invention relates to epoxy resin hardener compositions containing at least one mercaptan hardener and at least one metal salt of C8-24 carboxylic acids. These hardeners are distinguished in particular by the fact that catalyzed resins containing epoxy resins and the hardener compositions according to the invention give high-gloss molding compounds, more particularly coatings, after hardening by crosslinking.
Claims20
An epoxy resin hardener composition comprising at least one mercaptan hardener and at least one metal salt of a carboxylic acid having from about 8 to about 24 carbon atoms.
A method of hardening an epoxy resin comprising combining a composition comprising at least one mercaptan hardener and at least one metal salt of a carboxylic acid having from about 8 to about 24 carbon atoms with an epoxy resin.
A process for producing a high-gloss epoxy resin coating, said process comprising combining a component (A) comprising at least one epoxy resin and a component (B) comprising at least one mercaptan hardener and at least one metal salt of a carboxylic acid having from about 8 to about 24 carbon atoms, homogenizing the combination of component (A) and component (B) to form a catalyzed resin, and allowing said resin to cure.
