Frequently Asked Questions
Q
What is UV 1600 and what type of UV absorber is it?
UV 1600 (CAS: 204583-39-1) is a high-performance triazine-based ultraviolet (UV) absorber. It is supplied as a light yellow powder and is designed to provide superior photoaging protection with extremely low volatility and high UV absorption efficiency.
Q
Which materials is UV 1600 compatible with?
UV 1600 offers excellent compatibility with a wide range of polymer substrates, including polyurethanes, plastics, and polycarbonate (PC). It does not compromise material transparency and exhibits low coloration, making it ideal for high-clarity applications.
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 requires a lower dosage to achieve equivalent or superior protection.
Q
What are the key physical and chemical specifications of UV 1600?
UV 1600 meets the following key specifications: Assay (HPLC) ≥ 98.5%, Melting Point 120℃–130℃, Loss on Drying ≤ 0.2%, Ash content ≤ 0.1%, Transmittance in 2% toluene at 450nm ≥ 80% and at 500nm ≥ 90%, and Clarity in 10% Toluene: Clear.
Q
How does UV 1600 compare to conventional UV absorbers?
UV 1600 outperforms many conventional UV absorbers in several ways: it has extremely low volatility, requires a lower effective dosage, provides higher UV absorption efficiency, and maintains excellent material transparency without significant coloration — making it a cost-effective and high-performance choice.
Q
What is the primary function of UV 1600 in polymer applications?
The primary function of UV 1600 is to provide photoaging protection for high-transparency polymer materials. It absorbs harmful UV radiation and prevents degradation, discoloration, and loss of mechanical properties caused by prolonged exposure to sunlight or artificial UV light sources.
