ABSTRACT:
An air curable resin solution useful for surface coating and impregnation comprising (I) the reaction product of (A) from about 50% to about 65% by weight based upon the total weight of (A) and (B) of an epoxy resin ester of a partially conjugated unsaturated fatty acid and (B) from about 50% to about 35% by weight based upon the total weight of (A) and (B) of a blend of reactive monomer possessing reactive double bonds, at least one of which must be an unsaturated mono-basic acid in the presence of (II) an alcohol ether of a glycol and subsequently reacted with (III) an amine and then (IV) dispersed in water, wherein component (A) is the reaction product of 2,2,bis(4 hydroxy phenyl) dimethyl methane and epichlorohydrin, and has a melting point from about 130.degree. F. to about 230.degree. F. and an epoxide equivalent weight within the range from about 400 to about 1100, and the fatty acids used are straight chain monobasic acids of 18 carbon length having double bonds arranged in the chain in amount and position to give an iodine number of 125 to 185, an acid number of from about 180 to 210 and a percentage of conjugation of the double bonds between 20% and 25% wherein the reaction is carried out to an acid number below 10 and the monomer (B) portion consists of a mixture of 20-28% of unsaturated monobasic acids having a polymerizable double bond and 80% to 72% reactive monomers having a polymerizable double bond.
