A hardener composition comprising: a) an isolated adduct comprising a reaction product of i) a polymer with a functionality of at least three, wherein said polymer contains at least one epoxy group; and ii) an amine wherein the isolated adduct is present as an aqueous solution; and b) a capping agent. This hardener can be used with a liquid epoxy resin to form a curable composition.

Hardeners for cold-curing epoxy systems

A hardener composition comprising: a) an amine component; and b) a glycol ether component comprising i) from 10 weight percent to 70 weight percent alkylene glycol phenyl ether; ii) from 25 weight percent to 80 weight percent dialkylene glycol phenyl ether; iii) from 5 weight percent to 20 weight percent trialkylene glycol phenyl ether, is disclosed. The hardener composition can be used in epoxy thermoset formulations.

Low emission epoxy curing agents

A salicylic acid salt-containing liquid composition useful as an accelerator for a hardener includes a reaction product of (a) salicylic acid; and (b) at least one amine compound compatible with said salicylic acid such that the composition is in liquid form, the composition has a concentration of salicylic acid at from about 35 weight percent to about 55 weight percent, and the composition has a viscosity in the range of from about 500 mPas to about 20,000 mPa-s at 25&#xb0; C.; a curable epoxy resin composition containing the salicylic acid salt-containing liquid composition accelerator; and a cured product made from the curable composition.
