FURAN-BASED AMINES AS CURING AGENTS FOR EPOXY RESINS IN LOW VOC APPLICATIONS

摘要

A room temperature or low temperature curable epoxy formulation including a) an epoxy component including at least one epoxy resin and b) a hardener component including at least one compound of formula (I); wherein X is a divalent hydrocarbon group, which optionally contains one or more heteroatoms, and n is 0, 1, 2 or 3, preferably 0 or 1, and/or at least one epoxy-amine adduct, which is a reaction product of the compound of formula (I) and an epoxy compound selected from at least one of a monoepoxide and a polyepoxide, as a curing agent. The compounds of formula (I) and the epoxy-amine adduct are suitable as curing agents for epoxy formulations which provide good surface properties and good cure speed, even at low temperature curing. In particular, amine blushing can be avoided or reduced to a large extent, when these curing agents are used.
