Provided herein is a hardener composition comprising (a) a first adduct comprising a reaction product of a liquid epoxy resin and isophorone diamine; (b) a second adduct comprising a reaction product of a liquid epoxy resin and m-xylylenediamine; and (c) an accelerator component comprising methanesulfonic acid.

Hardener formulation for cold curing epoxy systems

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 accelerator comprising a first amine at least partially neutralized by salicylic acid and a first modifier; b) a non-isolated adduct of i) a difunctional epoxy; and ii) a second amine; and c) a second modifier, and a process for making the hardener composition, are disclosed. The hardener can be used with an epoxy resin to form a curable composition.

Fast curing agents for epdxy resins

Embodiments include curable compositions including a resin component and a hardener component. The resin component can include an epoxy compound that is selected from the group consisting of aromatic epoxy compounds, alicyclic epoxy compounds, aliphatic epoxy compounds, and combinations thereof, and a reactive diluent that includes a polymeric glycidyl ether. The hardener component can include an adduct and a Mannich base.
