Both products prevent the adhesion of carbonates and protect the system from oxidation and corrosion, the main difference being that FILMAX 9.0 is a corrosion inhibitor that should be used specifically in those cases where the liquid circulating in the system does not exert sufficient passivation on the metal parts of which it is composed, for example, after excessive exploitation of the circulating antifreeze, it becomes necessary to replenish the package of inhibitory salts.
