An Introduction to UV-P

UV-P is a benzotriazole-based UV absorber and light stabilizer that belongs to the family of hindered amine light stabilizers (HALS). It is a pale yellow powder with a molecular weight of 323.38 g/mol and a melting point of 139-144°C. UV-P is soluble in organic solvents such as acetone, chloroform, and toluene but insoluble in water.

Properties of UV-P

UV-P offers excellent UV absorption and light stabilization properties, making it ideal for use in a wide range of applications. It has a maximum absorption wavelength of 308-310 nm and an extinction coefficient of 43,000-48,000 L/mol·cm, indicating its high efficiency in absorbing UV radiation. Additionally, it has a high thermal stability of up to 280°C, making it suitable for use in high-temperature applications.

Applications of UV-P

UV-P is a versatile product that finds applications in various industries, including plastics, coatings, adhesives, and textiles. In the plastics industry, it is commonly used in polyolefins, PVC, polycarbonates, and polyesters to prevent UV-induced degradation, discoloration, and cracking. In coatings, it is used to improve the weatherability of paints, varnishes, and lacquers. It is also used in adhesives and sealants to enhance their UV resistance. In textiles, it is used to prevent the fading and yellowing of fibers and fabrics.

Benefits of UV-P

UV-P offers numerous benefits that make it a preferred choice for UV protection and light stabilization. Firstly, it is highly effective in absorbing UV radiation, thereby protecting materials from degradation and discoloration. It also offers excellent compatibility with various polymers and additives, allowing for easy incorporation into a formulation.
