Ferric Ions Chelating Agent XT-541 Properties: XT-541 is an organic complex with special function to ferric ions. It can be used as chelating agent in boiling-out and bleaching process, leveling and dispersing agent for reactive dye, direct dye and VAT dye. XT-541 does not contain phosphorus, without pollution to the environment. Specification: items index Appearance Colourless or pale yellow Powder Solid content % 97.0 min pH Value （1% water solution） Ionicity Anion Fe3+ chelating ability (mg/g) 1000 min Usage: 1. Scouring agent XT-541 can disperse dirts and impurities, chelate and disperse Cu, Fe ions in scouring liquid. It can help removing yellow spot and prevent the fabrics become yellowing, thus improving their vividness. Recommended dosage is 1-6g/L. 2. Bleaching agent When added into bleaching liquor, XT-541 have a good chelating ability to Fe,Cu, and prevent fabrics from strength decline and small holes, improve whiteness obviously. XT-541 can block off metal ions, indirectly control decomposition speed of hydrogen peroxide. Recommended dosage is 3-6g/L 3. When soaping, XT-541 can prevent stains and white defiled. Recommended dosage is 1-2g/L Package and Storage: Normally In 25kg net plastic woven bag. Storage for twelve months in room shady and dry place.
