1,2,3 benzotrazole(BTA)
Properties:
It is solved slightly in the water and the aqueous solution of which is of weak acidic. It can be formed into covalent bond and coordination bond with the metal atom such as copper and silver, and bond polymer through mutual alternated so as t oavoid any corrosion.
Usage:
It is not only an excellent corrosion inhibitor for various metals, such as copper and silver, etc, but also a superior ultraviolet absorber. Its product can be wildly used in the water treatment for power generation industry, petrochemical industry and dyeing industry.
Columnar and tablet BTA is produced through the mechanical shaping and trimming from the crystal of BTA. The size can be sadjusted according to the requirement of the customers. Since it has a bulk density of 600-700kg/m3, there is little dust to be produced during the application which is good for the long distance transportation.
