Highly effective broad-spectrum UV absorption in the 300–400 nm range, with peak absorption at ~345 nm.
Excellent compatibility and solubility in a wide range of polymer matrices and coating resins, including acrylics, polyesters, and alkyds.
Low volatility and high thermal stability, enabling use in high-temperature processing (e.g., extrusion, injection molding).
Good hydrolytic stability and resistance to extraction, ensuring long-term performance in demanding outdoor applications.
Non-discoloring and chemically inert—does not interfere with curing reactions or catalyst systems in coatings and adhesives.
Automotive clearcoats and basecoats for enhanced gloss retention and resistance to chalking.
Industrial maintenance coatings exposed to intense sunlight and weathering cycles.
Plastic packaging films requiring UV protection for light-sensitive contents (e.g., agrochemicals, pharmaceuticals).
Exterior architectural coatings, including elastomeric and silicone-modified acrylic systems.
Engineering thermoplastics such as polycarbonate and ABS used in outdoor consumer electronics and automotive components.
