Chelatin-SA is a multifunctional auxiliary developed as an efficient sequestering, dispersing (protective colloid) and chelating agent for all stages in wet processing and dyeing of cellulosic and its blends. It can be also used for pre-treatment with Hydrogen Peroxide as a stabiliser in bleach bath. It has excellent Ca & Fe Chelation values even at pH values of 9-11.
Chelatin-SA is a sugar acrylate polymer with a very good biodegradability. It does not increase the COD/BOD values in the effluent.
It is suitable for both batch as well as continuous process.
