  • Hardeners for cold-curing epoxy systems
    Patent number: 10160826
    Abstract: 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.
