Product Overview
UV Absorber 384-2 represents a sophisticated class of liquid benzotriazole ultraviolet stabilizers specifically engineered for high-performance protective coatings and polymer systems. This specialized chemical additive functions through a mechanism of absorbing harmful ultraviolet radiation across critical wavelengths and dissipating the energy as harmless thermal heat. This process effectively prevents photo-oxidative degradation of the polymer matrix, thereby extending the service life of coated substrates significantly.
Its unique liquid physical form ensures effortless integration into various solvent-borne and water-borne systems without compromising clarity, viscosity, or processing efficiency. Unlike solid alternatives, this liquid grade eliminates dispersion issues, ensuring homogeneous distribution within the final formulation. Manufactured under strict quality control standards, this product delivers consistent protection against severe weathering effects such as gloss loss, micro-cracking, chalking, and substrate erosion.

Industrial Applications
The versatility of UV Absorber 384-2 makes it indispensable across multiple high-value industries requiring durable exterior finishes. In the automotive sector, it is extensively used in OEM clear coats and refinish systems to maintain aesthetic appeal and structural integrity over the vehicle lifespan. Industrial coil coatings benefit from its exceptional thermal stability during high-temperature curing processes, ensuring long-term facade protection for architectural cladding and roofing materials.
Furthermore, wood coatings utilize this absorber to prevent lignin degradation and color fading caused by prolonged solar exposure. Its compatibility with modern water-borne formulations aligns with stringent environmental regulations, allowing manufacturers to meet volatile organic compound limits while maintaining superior performance standards. It is also suitable for general industrial applications including plastic coatings and protective films.
