Optical Brightener KSN
CAS # 5424-49-9
Optical Brightener KSN is a fluorescent whitening agent specifically used to enhance the brightness and whiteness of plastics, synthetic fibers, coatings, and specialty materials.
Description:
Optical Brightener KSN is a high-performance fluorescent whitening agent designed to enhance the brightness, whiteness, and visual appeal of plastics, synthetic fibers, coatings, and specialty materials. KSN effectively offsets yellowing and dullness by absorbing ultraviolet light and re-emitting it as visible blue light. Its excellent thermal stability and compatibility with a wide range of polymers make it a preferred choice for manufacturers seeking superior optical performance and long-lasting brightness.
