Benzophenone UV Absorber

Image
  Benzophenone UV  absorbers are general purpose UV absorbers commonly used in polyolefin applications and can be incorporated into a range of polymer products. These benzophenone UV absorbers have good absorption in the wavelength range from 260 to 350 nm and are stable throughout processing.   Benzophenone UV absorber s have excellent compatibility with various resins and are widely used not only as plastic additives but also in applications such as coatings and synthetic resin adhesives.   Benzophenone UV absorbers provide protection for thick and thin sections and are optimized when used in unpigmented or lightly tinted formulations. When used in combination with hindered amine light stabilizers (HALS), the benzophenone UV protection can be improved, especially when stabilizing thin sections.   Since 1989, TINTOLL has actively participated in the development of innovative light stabilizers and application research, and currently has more than 100 specialty p...
