NC-603(HS123NC)TTA & NC-604(HS124NC)TTAS
This product is cheaper than BTA, and has better anti-oxidization and higher corrosion inhibition effects. So, American companies usually use it as copper and iron corrosion inhibitors. Our products TTA is the only one who could reach the American PMC quality standards in China.
