Zinc Chloride
White crystalline solid, highly hygroscopic · CAS 7646-85-7
Overview
Zinc Chloride (CAS 7646-85-7) is one of the metal salts & inorganic compounds products Suraj Chemicals supplies to industrial, institutional and manufacturing buyers across India from our Chennai base. It is commonly used for flux in hot-dip galvanising and soldering; textile processing (mercerising / vulcanised-fibre manufacture); wood-preservative and fireproofing treatment, among other applications in the metal salts & inorganic compounds category. We pack Zinc Chloride in 25/50 kg HDPE bags/drums (moisture-proof lined), and can arrange bulk, drum or tanker quantities for larger requirements — full characteristics, applications and downloadable documentation are below, or you can request a quote directly.
