Q1: What is Appolo-1579 (A-103) used for in the textile industry?
A1: Appolo-1579 is an HPT UV absorber (CAS 106556-36-9, C22H17N3O2, mol. wt. 355) used in dip-dyeing of PET fiber (Terylene), non-woven fabrics for face masks and PPE, polycarbonates, thermoplastics, fibers, and carpets to improve durability, color fastness, and UV protection.
Q2: Can Appolo-1579 protect both the fiber and the dyestuff simultaneously?
A2: Yes — a key feature of Appolo-1579 is that it can protect both the PET fiber substrate and the dyestuff within it from UV-induced degradation, making it particularly effective in processing of heat-treated PET.
Q3: What physical specifications does Appolo-1579 (A-103) meet?
A3: It's a yellow powder with melting point 205–207°C, purity by HPLC NLT 98.0%, loss on drying NMT 0.50%, and transmittance at 500 nm (2% in NMP) NLT 65.0%.
Q4: Is Appolo-1579 (A-103) used in any non-textile applications?
A4: Yes — while primarily a textile UV absorber, it's also used in polycarbonate injection molding, general thermoplastics, automotive coatings, and general plastics, making it a cross-industry product.
Q5: Who manufactures and exports Appolo-1579 (A-103) from India?
A5: Sarex manufactures Appolo-1579 (A-103) at 80 MT annual capacity in India. As a leading fine chemical manufacturer and one of India's largest chemical exporters, Sarex supplies it in jumbo bags (250–300 kg net) to customers across 40+ countries.
