Galvanizing Chemicals Our ROTO range of
products is best efficient and economical operations for Hot Dip Galvanizing.
Our ROTO FLUX Series
of hot dip galvanizing fluxes helps in controlling the formation of zinc oxides
by assisting reaction of molten zinc. In a normal hot dip galvanizing process,
surface contamination and scale from iron and steel can be removed by cleaning
processes like degreasing, pickling and water rinsing. But minute impurities in
the form of oxides, chloride, sulfates and sulfides are retained, which if not
removed can get in the way of the iron-zinc reaction when the iron or steel
part will be immersed in molten zinc. These can be removed by our ROTO FLUX.
Further, it should also have enough chemical stability to uphold chemically
active foam at the galvanizing temperature and to execute its cleaning function
at a high speed. Our galvanizing flux is best in the industry
We also offer Zinc
chloride, Zinc Ammonium Chloride, Ammonium Chloride, corrosion inhibitors ,
metal degreaser and white rust preventive.
In addition, we also
offer fume suppressants for hot dip galvanizing and electroplating
