BTA is used as antirust of metals, such as silver, copper, lead, nickel and zinc. BTA is used as widely used for products of slushing oil (grease), mainly used for vapor phase corrosion inhibitor of copper or copper alloy. BTA is used as treating compound of cycle water, antifreeze of auto, fog preventative for taking pictures, macromolecule stabilizer, ethylene chlorohydrin, lube oil additive, ultraviolet absorber. BTA can also be used with many dirty-resistance agents and sterilized algaecide, especially for the corrosion mitigation effect of the airproofing circulation cooling water system.

Package and Storage:

Net weight is 20kg, plastic weaving bag or according to demand of clients.

BTA should be put in the ventilation and dry place. It is forbidden to place it together with food and seeds.
