Abstract
Abstract Water-based curable epoxy resin compositions comprising (A) a diglycidyl ether of a bisphenol A type resin and (B) a reactive polyamidopolyamine can avoid problems resulting from the use of solvents and emulsifiers if the diglycidyl ether (A) has been partially reacted (preferably to an extent from 5 to 50%) with a polyoxyalkylene polyamine having a molecular weight from 900 to 5000. Preferred polyoxyalkylene polyamines have the formulae: wherein y is 1-5, and z is 1-50, or wherein r is 16-20 and s is 1-5.

Claim 1
Independent Claim
78 words
A curable epoxy resin composition comprising: (A) a diglycidyl ether comprising a condensation product of (a) epichlorohydrin with (b) a bisphenol A type resin or derivative thereof; and (B) a reactive polyamidopolyamine prepared from reaction of a multi-functional carboxylic acid, ester, anhydride or mixture thereof with a polyfunctional aliphatic, cycloaliphatic or aromatic polyfunctional amine, or a mixture thereof, characterized in that diglycidyl ether has been partially reacted with a polyoxyalkyleneamine having a molecular weight of 900 to 5000.
Claim 2
Dependent Claim
78 words
A curable epoxy resin composition comprising: (A) a diglycidyl ether comprising a condensation product of (a) epichlorohydrin with (b) a bisphenol A type resin or derivative thereof; and (B) a reactive polyamidopolyamine prepared from reaction of a multi-functional carboxylic acid, ester, anhydride or mixture thereof with a polyfunctional aliphatic, cycloaliphatic or aromatic polyfunctional amine, or a mixture thereof, characterized in that diglycidyl ether has been partially reacted with a polyoxyalkyleneamine having a molecular weight of 900 to 5000.
