Product Introduction: White crystalline powder
Use: EDTA 2Na is an important complexing agent. For silvering solution before the copper plating, gold-plated, pewter, iron and steel parts and pieces of copper in the electrochemical polishing, it can also be used in place of EDTA-Na. Also used in detergents, liquid soap, shampoo, agricultural chemical sprays, color photographic materials Processing bleach fixer, purifying agent, PH adjusting agents, anti-coagulant agents. In the styrene-butadiene rubber polymerization initiators are redox systems, EDTA disodium as part of an active agent, mainly for complex ferrous ions, controlling the polymerization rate.
