SINOSORB® UV-400 is a triazine-based liquid UV absorber used in the coatings industry. It contains hydroxyl groups and exhibits low migration effects. It is typically used in combination with hindered amine light stabilizers and shows good compatibility with solvent-based and water based coating systems. Due to its light color and good photostability, it is also particularly suitable for UV-cured coatings.

Q1: What is Sinosorb® UV-400 and what is its chemical composition?
A: Sinosorb® UV-400 is a premium industrial-grade liquid ultraviolet absorber belonging to the class of hydroxyphenyl-triazines. Chemically, it is a multi-component solution optimized for low viscosity, containing roughly 85% of active triazine compound (CAS 153519-44-9) and 15% of 1-methoxy-2-propanol (CAS 107-98-2) serving as a compatible formulation solvent.
Q2: How does a triazine UV absorber like Sinosorb® UV-400 compare to traditional benzotriazole UV absorbers?
A: Hydroxyphenyl-triazine (HPT) absorbers like Sinosorb® UV-400 exhibit far superior photostability and long-term durability under extreme outdoor stress than standard benzotriazoles (such as UV 328 or UV 928). Triazines are highly resistant to photo-permanent loss and chemical migration. This makes them the definitive industry choice for demanding industrial applications like automotive OEM coatings where long-lasting performance is critical.
