Neutralization in situ with 28% ammonium hydroxide, or with a water-soluble amine, increases the water solubility of the anhydride. In this form, the products will exhibit wetting and dispersing properties similar to their potassium salts. However, the amine neutralized salts may show superior anti-rust qualities. If the amine used is relatively volatile, it will evaporate during drying, permitting the surfactant to revert to the free-acid form. Because these free acids have less water affinity, the coatings will exhibit lower water sensitivity. This mechanism of reversion to the free-acid form also prevents inhibition of crosslinking, and in some cases, acceleration of cure has also been noted. STRODEX P-100 is particularly recommended for use in water-reducible aklyd high-gloss enamel formulations to help stabilize the cobalt and zirconium drier-catalysts against hydrolysis and loss-of-dry activity at elevated pH levels.
