The bisphenol A should be dissolved in the 3-methoxy butanol by heating to 125'F. accompanied by vigorous stirring. It is unnecessary to add any corrosion inhibitor since the "Hydricin" 4 has already been processed to inhibit any corrosion tendency of the finished fluid. For pH adjustor, add Dibutylamine preferably to "Celanese" Solvent 901-H with stirring but order of addition is not critical.
