Frequently Asked Questions
Q
What is UV 1600 and what type of UV absorber is it?
UV 1600 (CAS No. 204583-39-1) is a high-performance triazine-based ultraviolet (UV) absorber. It is designed to provide superior photoaging protection with extremely low volatility, high UV absorption efficiency, and excellent compatibility with a wide range of polymer substrates.
Q
What materials is UV 1600 suitable for?
UV 1600 is particularly well-suited for high-transparency materials that require photoaging protection, including polyurethanes, various plastics, and polycarbonate (PC) substrates. Its low coloration ensures it does not compromise the optical clarity of the final product.
Q
What is the recommended dosage of UV 1600?
The recommended dosage of UV 1600 ranges from 0.2% to 6.0% by weight relative to the target material. Compared to conventional UV absorbers, UV 1600 typically enables lower dosage requirements while maintaining effective protection.
Q
What are the key physical and chemical specifications of UV 1600?
UV 1600 appears as a light yellow powder with a melting point of 120℃–130℃. Its purity by HPLC assay is a minimum of 98.5%, with loss on drying not exceeding 0.2% and ash content not exceeding 0.1%. It also demonstrates high transmittance in 2% toluene solution (≥80% at 450nm, ≥90% at 500nm) and clear clarity in 10% toluene.
Q
Does UV 1600 affect the transparency of the substrate?
No. One of the key advantages of UV 1600 is that it does not compromise material transparency. Its low coloration and high transmittance values make it ideal for applications where optical clarity is critical, such as PC films, transparent coatings, and clear polyurethane systems.
Q
How does UV 1600 compare to conventional UV absorbers?
UV 1600 offers several advantages over conventional UV absorbers: it has extremely low volatility, which ensures long-lasting performance; it provides high UV absorption efficiency at lower dosage levels; and it exhibits excellent compatibility with diverse polymer systems. These properties make it a cost-effective and high-performance choice for demanding applications.
