Water dispersible polyamine-epoxy adduct and epoxy coating composition. |
摘要 |
<p>This invention relates to a water compatible polyamine-epoxy adduct formed by the reaction of a polyamine with a mixture of a monoepoxide and polyepoxides, the monoepoxide being added in an amount to react with about 10 to 50% of the primary amino groups in said polyamine and the polyepoxides being added in an amount to react with from about 35 to 65% of the remaining primary amino groups. This invention also contemplates a water dispersible blend resin as an amine salt and comprises a water compatible polyamine-epoxy adduct and a resin compatible polyamine-epoxy adduct wherein the water compatible polyamine-epoxy adduct is as described above and the resin compatible polyamine-epoxy adduct is formed by reacting a polyamine with an aromatic monoepoxide, said aromatic monoepoxide reacted in an amount to provide from about 0.4 to 1 equivalents epoxide per primary amino group. The invention also pertains to a two component water epoxy coating composition comprising an aqueous dispersion of a blend of a water compatible polyamine-epoxy adduct, a resin compatible-polyamine-epoxy adduct and a polyepoxide resin emulsified therewith wherein the amount of polyepoxide resin in the coating composition is such that there is from about 0.5 to 1.5 equivalents epoxide per active hydrogen equivalent.</p> |
