The product is an aqueous dispersion with a high degree of stability, thus avoiding discoloration by reaction with different elements in some coating formulations. In particular, the reaction of soluble iron with the active ingredient in ZINC OMADINE may lead to a gray-blue discoloration reaction. By using ZINCOMADINE ZOE antimicrobial agent, the reaction of iron with the active ingredient in ZINCOMADINE can be slowed down.
