ABSTRACT:
Hydrophobic, thermoset resins having highly desirable properties in coatings applications can be prepared from novel, water-thinnable, base-neutralized, acidic reaction products of orthophosphoric acid with hydrophobic, nominally-difunctional polyether epoxide resins having average epoxide equivalent weights (EEW) of from about 172 to about 5500. The phosphate groups in these products, when formed with fugitive bases, are thermally decomposable to yield resins which are not rapidly self-converting as such but are rapidly heat convertible in admixture with any of several types of curing agents. The functional groups responsible for water solubilization are utilized (and reacted out) in curing of the resins. The invention provides a method of utilizing hydrophobic, high performance polyether epoxide type polymers in aqueous coating systems having the ability to wet metal surfaces.
