Z-21

Saru Z-21 is a revolutionary flux and has been especially formulated to reduce physically entrapped zinc and zinc oxide formation substantially in hot Dip galvanizing process. “SAZU” Z-21 flux melts at 194 ‘C (300’F) coats the liquid and then combines with the oxide particles assuring rapid reaction. Fumes and objectional smoke are minimized and the surface of the metal is protected from oxidation.

How Does ‘Saru’ Z-21 Function
As soon as ‘SARU’ Z-21 flux is added in the bath it gives a molten foamy layer cover on the whole bath thereby protecting the molten metal from atmospheric-oxygen, reduces formation of zinc ash to as low as 6-10% of every day consumption in comparison to 12 to 16% with the conventional method being followed.

A comparative study is given below between conventional process and with SARU Z-21 flux process.

Bath	Method	Zinc consumption	Wt. of ash	% loss on
capacity	employed	every day	collected every day	zinc consumed
60 tonnes	conventional	6 tonnes	960 kgs.	16%
60 tonnes	‘SARU’	6 tonnes	480 kgs.	8.00%
	Z-21 ‘FLUX’

‘SARU’ Z-21 (Wonder Flux)
This is a smokeless Galvanising Flux and is almost twice as efficient as regular Z-21 reducing Zinc Ash formation to as low as 3-5%.

Advantages of Saru Z-21 Flux

Reduces formation of zinc oxide and physically entrapped zinc from 12-16% to 6-8% on total zinc consumption every day.
Helps in giving uniform zinc coating on the galvanizing objects.
Reduces zinc dust.
Brighter piper, tubes.
Very convenient to use.
