Claims11
A two-part water-borne epoxy coating composition comprising a resin base portion and a hardener portion;
- said resin base portion comprising in percent by weight:
- ______________________________________ a bisphenol A epoxy resin having 30 to 45 a viscosity of about 500 to 700 cps, a mixture consisting of about 4 1.0 to 2.5 parts by weight of nonylphenoxypoly (n = 40 ethyleneoxy) - ethanol and 3 parts by weight of nonylphenoxypoly (n = 44 ethyleneoxy) - ethanol, a long chain organic phosphatide, 0.1 to 0.5 defoaming agents, 0.3 to 0.1 co-solvents, 3.5 to 6.0 pigments, 0 to 40 water Q.S. 100 ______________________________________
- and said hardener portion comprising in percent by weight:
- ______________________________________ a blend of polyamido-amines, said blend 75 to 85 containing about 59.0 to 85.0 percent by weight of water-soluble modified polyamido-amines having a molecular weight of about 2,000 to 18,000 and derived from fatty acids having a chain length of about 18 carbon atoms and aliphatic diamines and about 15.0 to 41.0 percent by weight of water- soluble polyamido-amines having a molecular weight of about 2,000 to 15,000 and derived from dimeric fatty acids having a chain length of about 36 carbon atoms and ethylene diamine, co-solvents 1.0 to 8.0 water Q.S. 100 ______________________________________
