US 2015/0105523 A1 · EPOXY RESIN HARDENER COMPOSITIONS AND EPOXY RESIN COMPOSITIONS CONTAINING SUCH HARDENER COMPOSITIONS

Abstract

An epoxy resin hardener composition including a reaction product of (i) a compound having at least one vicinal epoxy group, and (ii) an amino alcohol; an epoxy resin composition including the epoxy resin hardener composition and a compound having at least one vicinal epoxy group; and a powder coating composition including particles of the epoxy resin hardener composition and particles of a compound having at least one vicinal epoxy group.

Claims8

Dependent claims

A solid amino functional hardener composition comprising a reaction product of:

(i) a compound having at least one vicinal epoxy group;
and
(ii) an amino alcohol having at least one amino group and at least one alcohol group, where the at least one amino group of the amino alcohol are primary amino groups and a mole ratio of amine groups of the amino alcohol is in excess of the epoxy groups of the compound having at least one vicinal epoxy group in the range of from 25:1 to 3:1.

Dependencies are inferred from the claim text.
