Specification of  Zinc Chloride (Anhydrous)

Ammonium chloride

This is one of our specialties in our diverse range of our chemicals. Our Zinc Ammonium Chloride based on low fuming formulated liquid flux; these are specially formulated for continuous Wet Flux Galvanizing lines or a new flux charge in a batch process. These are ideal for Wet Flux Galvanizing lines or a new flux charge in a batch process since during formulation it reduces the fuming
