Purpose

Used for processing of color photosensitive materials Bleach fixer, activator of styrene-butadiene rubber, hard water softener, sequestering agent, etc. EDTATetrasodium in various speciespHIt has the ability to complex calcium-containing hard water within a range and at various concentrations, and inpH≥8 is most effective. With calcium metal to1：1More ratio complex, has excellent thermal stability in water, and will not decompose even in superheated water. It is a very effective hard water softener. This product is non-toxic.
