Phenethyl alcohol

In electroplating, it is used for surface purity silver, copper, zinc, and has anti-discoloration effect.
BTA and copper atoms form covalent bonds and coordination bond, more for each other into a polymer chain, on the copper surface of multilayer protective film, can't afford to make the surface of the copper REDOX reaction, hydrogen does not occur, corrosion protective role.
It also has the same effect on metal materials such as lead, cast iron, nickel and zinc.
BTA can be combined with various corrosion inhibitors to improve the effect of corrosion.
Can also be used with a variety of scale inhibitors, algae fungicidal, especially for closed circulating cooling water system corrosion effect well, ethylene glycol and water in automotive antifreeze, adding BTA can volatilize protection coating material.
BTA as good ultraviolet absorbent, products that are sensitive to uv light can have the effect of stability, prevent the diazo dyes fade, for example, deal with paper, knitting, with BTA film laminate can prevent discoloration, metal COINS.
In the process of machining, BTA will be added to the grinding oil and cutting oil, which will make the copper parts not discolored.
The product can also be used as an analytical reagent for the use of ammonia and diamine tetraacetic acid, which can be used selectively to determine silver, copper and zinc.
It can also be used as a photographic anti-grey spray and organic synthesis intermediates.
USES for analytical reagents and photographic antifogs, and also for organic synthesis
