1,2,3-Benzotrialole (BTA)
1,2,3-Benzotrialole (BTA) can be absorbed
on metal surface and form a thin film to protect copper
and other metals.
BTA can be used together with
many scale inhibitors and fungi disinfectants in
circulating cool water system,
BTA has good corrosion
inhibition effect in circulating cool water system. The
dosage of 2-4mg/L is preferred.
BTA can also be used as
anti-discolor agent, coating additives and luboil
additive.
2-Mercaptobenzothiazole (MBT)
2-Mercaptobenzothiazole
(MBT)
can be used as the copper corrosion inhibitor in
circulating cool water system. The mechanism is due to
the chemical absorption of
MBT on copper surface, or
chelation reaction between them. The dosage of 4mg/L is
preferred.
MBT can also be used as
plasticizer and photometer for acid copper plating.
Methylbenzotriazole
(TTA)
Methylbenzotriazole
(TTA)
can be used as corrosion inhibitor of copper and copper
alloy, TTA also has corrosion
inhibition for black metals.
TTA is absorbed on metal
surface to form a thin membrane to protect copper and
other metals from corrosion of air and other harmful
subjects. The membrane is more uniform. When used
together with
MBT, the effect is better.
