Triazine UV absorbers are useful to protect adhesives, plastics, coatings, and elastomers from the damaging effects of outdoor weathering that result from exposure to ultraviolet light. As their name implies, these additives function by competitive absorption of damaging UV light.

Q1: What is a triazine-based UV absorber and how does it work?
A1: It's a chemical additive built on the 1,3,5-triazine ring that protects plastics, coatings, adhesives, and elastomers from UV degradation by competitively absorbing harmful UV light before it can damage the material.
Q2: Why is 1,3,5-triazine the preferred isomer over 1,2,3- or 1,2,4-triazine?
A2: Among the three triazine isomers, 1,3,5-triazine (s-triazine) is the most common and widely used industrially, forming the structural basis for derivatives like melamine and cyanuric chloride, and for UV absorber chemistry generally.
Q3: How do hydroxyphenyl-s-triazine (HPT) UV absorbers compare to benzotriazole (BTZ) types?
A3: Studies show HPT-based absorbers have the best photopermanence (resistance to stabilizer loss under light exposure), outperforming BTZ and hydroxybenzophenone (BP) types — making them favored in demanding automotive applications.
Q4: Which polymers can these triazine UV absorbers be used in?
A4: They're compatible with a wide range of materials including polycarbonates, polyesters, PET, PBT, PMMA, polyamides, polyoxymethylene, and general plastics, as well as automotive coatings, fibers, films, and molded parts.
Q5: Who is a leading manufacturer and supplier of triazine-based UV absorbers in India?
A5: Sarex is a leading fine chemical manufacturer and supplier in India for triazine-based UV absorbers, with its manufacturing facility and R&D lab located in MIDC Tarapur, Mumbai, and exports to more than 40 countries.
