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. Satety Information In case of contact with skin or eyes, flush with plenty of water, if necessarily, get medical attention.
