● 100 L BONDERITE M-NT 811 are added to 100 L of
deionized water in the make-up tank whilst using
continuous agitation.
● Further deionized water is added to give a total volume
of 500 L again, whilst using continuous agitation.
● This corresponds to a make-up concentration of 20 %
(v./v.).
With a wet film of 4 mL/m2, the following dry film coating
weights expressed as zirconium are obtained:
