Double salt are tailor-made to suit specific requirements for galvanizing of tubes, sheets, structures, wires, nut-bolts and buckets etc. This is pre flux performs superior in comparison to the conventional flux by reducing:
- Dross generation
- Zinc Oxidation
- Occurrences of black spots by 100%
Besides the above direct benefits, it also provides many indirect benefits such as:
- Least air pollution
- Mild corrosiveness towards steel structures
- very high film life
- single pack system
Other characteristics are as follows:
- White to Yellowish, crystalline powder
- Hygroscopic
- Easily soluble in water
- Low drying temperatures
- Tolerates aluminum contents in Zinc bath up to 0.02%
- Stable up to galvanizing tempearture
The above benefits are derived as Galvaflux has a balanced zinc/ammonium chloride ratio blended with surfactants, film formers oxidants and flocculants.
