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.
