The hot galvanizing help bath additive ZinCooler TM TSD contains special surface active ingredients，with a strong penetration and wetting ability，which can form a continuous uniform thin layer on the surface of the plated parts，greatly reducing the surface tension of the plating solution，greatly improving the surface wettability of the plating solution and the plated parts，and following the traditional hot galvanizing process of a century old，thus achieving substantial breakthroughs in many aspects.
