Applications
- Ethylenediamine tetraacetic acid (EDTA) is an excellent chelating agent of calcium and magnesium ions, used as a chelating agent for water emulsion polymerization, to remove Ca2+, Mg2+, Fe2+, Fe3+ and other metal ions. It is also used as a complexing agent of anaerobic glue. It is used to treat methacrylate diester with EDTA to remove transition metal ions and eliminate the effect of promoting the decomposition of peroxide, which has a very good effect on improving the stability of anaerobic glue.
- Water softener, for boiler water softening and prevent scaling.
- Used as dyeing additive, fiber treatment agent, cosmetic additive, blood anticoagulant, water treatment agent, rubber polymerization initiator, PVC heat stabilizer, etc.
Packaging
EDTA is available in 25kg woven bags, Poly lined with pallets.
