Document Type and Number:
Japanese Patent JP2836812
Kind Code:
B2
Abstract:
A new epoxy hardener composition is the product of the reaction of (A) a poly(alkylene oxide) monoamine or diamine with a molecular weight (Mn) of about 500 to 3000 and (B) a di- or polycarboxylic acid, in a ratio of moles of carboxylic acid to equivalents of amine of about 1:1 to 6:1 to yield an intermediate (C), which in a second step is reacted with (D) a di- or polyamine. The compositions of the invention are excellent emulsifiers of liquid epoxy resins in aqueous media without the addition of added surfactants or acidic compounds, and can be used to prepare water resistant water-borne coatings and related products from both liquid and solid epoxy resins, that possess long pot lives and contain relatively small amounts of volatile organic compounds.
