Applications

Anti-Smut® 100 is recommended for use in all types of nitric acid etch solutions (for example,
etch inspection of high strength, low alloy steel parts).
A typical composition for a temper etch solution would be as follows:
• 0.5 – 5% v/v Nitric Acid
• 3 – 5% Antismut 100
• remainder – water
Anti-Smut® 100 should be incorporated into the
etch solution at ambient temperature. Slight
manual agitation of the bath may be required to
ensure complete homogeneity
