A curable composition comprising
a) an epoxy resin containing on average more than one epoxy group per molecule, and
b) as curing agent a composition consisting of
b1) 40 - 100 wt% of an reaction product from the reaction of
b1a) a diglycidyl- and/or monoglycidylether with
b1b) a composition comprising a volatile monoamine and a polyamine, said composition b1b) is used in an amount to provide an excess amino groups relative to epoxy groups from b1a), and whereby the excess of monoamine is removed off from the reaction product,
b2) 0 - 60 wt% of a polyamine, and
b3) 0 - 25 wt% of a polyphenol novolac,
and whereby the sum of components b1), b2) and b3) is 100 wt%,
providing long pot life combined with fast cure times at low temperatures,
thus making said compositions especially useful for marine and offshore coatings, industrial maintenance, construction, tank and pipe linings, adhesive, automobile and electrical potting applications. |
