BONDERITE M-AD 130 acts as an oxidizing agent (depolarizer) within the phosphating reaction kinetics. By oxidizing the nascent hydrogen gas formed at the cathodic sites during the acid attack, it prevents polarization of the surface. This acceleration shifts the equilibrium, promoting the rapid precipitation of Hopeite and Phosphophyllite crystals. The result is a denser coating weight achieved in shorter contact times, with reduced porosity and enhanced corrosion resistance.
