Product introduction 
     TINUVIN 99-2 is a liquid benzotriazole UV absorber developed for the coating industry. Its excellent thermal stability and weather resistance are especially suitable for high temperature baking paints and coatings used in harsh conditions. TINUVIN 99-2 gives office and industrial coatings a very high cost performance and longevity. It has a wide absorption range for UV light, and can directly absorb harmful rays irradiated on UV-sensitive coatings, such as wood paint and plastic paint.

 Scope of application
      TINUVIN 99-2 is recommended for commercial paints: such as boss desk wood paints and decorative varnishes; industrial paints; high temperature baking paints such as coil coatings.
Due to the color problem of TINUVIN 99-2, it can be replaced by benzotriazole UV absorber TINUVIN 384-2.
TINUVIN 99-2 can produce a synergistic effect with hindered amine light stabilizer TINUVIN 292/123, which can further inhibit or slow down the photo-deformation, cracking, chalking, discoloration and other phenomena of the coating.
TINUVIN 99-2 is well dispersed in water-based systems, as long as it is dissolved in co-solvents such as ethylene glycol monobutyl ether.
