Product Usage-NaSIPA

• As the third monomer of the cationically modified polyester CDP, it is mainly used for polyester, film and the like.
• Sodium isophthalate 5-sulfonate (5-SSIPA) is commonly used to prepare amine-free aqueous polyester resins and aqueous polyurethanes suitable for use in a variety of coatings.
• Generally, the structure of the reactive aromatic dibasic acid is similar to Eastman PIA (refined isophthalic acid).
• The aromatic ring structure gives the coating excellent hardness and high gloss.
• A lithium ion compound similar to 5-SSIPA is a more polar monomer that imparts greater water solubility to the resin, so it is added in smaller amounts when used.
• 5-SSIPA is a monomer for polyester resins for synthetic food packaging adhesives and has been approved by the FDA.
• A water-soluble polyester resin having a high acid value is obtained, and after further neutralizing with an amine, a water-soluble salt can be obtained.
• The polyester resin synthesized with 5-SSIPA is an aqueous polyester due to the ionic character exhibited by the sodium sulfonate group of 5-SSIPA.
• Characteristics：Water-dispersed resin does not require the use of an amine neutralizer, and the coating has excellent hardness and high gloss.
• Improves the colorability and light resistance of polyester and nylon fibers. Better PET printability for inks.Excellent interlaminar adhesion of tape.
