5-Sulfoisophthalic acid monosodium salt

Details:

CAS Number 6362-79-4 Specification Appearance Solid ( Powder ) Color White Odor Slight Purity ＞ 92% Moisture ＜ 6% Free Sulfuric Acid ＜ 0.1% Sodium Sulfate ＜ 2% pH ( 1% weight ) ＜ 7 Solubility in Water ( 25   ) Soluble (>600 g / 1000 g water) APHA Color ( 5 wt % Water Solution ) ≦ 40 Brief Description DD 5-SSIPA can be used as the third monomer to produce amine-free water dispersible polyester and nylon. This is the contribution of the sodiosulfo group in 5-SSIPA providing the ionic character needed for water dispersibility. It is also able to be used to prepare polyurethane dispersions for various coating applications. Since 5-SSIPA is an aromatic diacid stucture, its aromatic ring affords excellent hardness and high gloss properties to coating films. Brief Description ★ Water-soluble polymer such as CO-PET (Copolymerized Poly ethlyene terephthalate) and so on. ★ Water-dispersible attributes on polyester, nylon, and so on. ★ Improving printability of inks. ★ Creating good dyeability in polyester and nylon fibers. ★ Affording excellent hardness and high gloss properties for coating films. ★ Used as the material and catalyst in chemistry, agricultural chemical, medicine and other fields. Package Packed in 15 kgs of each PP woven bag with a PE inner bag. Storage Keep in dark and dry place, and avoid sunshine.
