Product introduction 
      TINUVIN 123 is a new type of liquid hindered amine light stabilizer, PH is neutral to avoid reacting with the acid catalyst in the coating. It can protect the coating from cracking, tarnishing and other minor changes.

Scope of application  
TINUVIN 123 is recommended for: automotive paints, industrial paints, decorative paints, wood paints, varnishes, etc.
TINUVIN 123 is suitable for high solids, acid catalyzed automotive and industrial paints such as two-pack heat-curing acrylic metallic paint systems, one-pack heat-curing acrylic, polyester coatings.
TINUVIN 123 has demonstrated efficient photostability in the following applications:

Air-drying automotive refinish coatings based on alkyd/acrylic systems
Air-drying alkyd paint, varnish
Two-component PU paint

Liquid TINUVIN 123 is also readily compatible with aqueous systems.
TINUVIN 123 can form a synergistic effect with UV absorbers for better results:

In automotive paints, it can be added together with UV absorber TINUVIN 1130 to achieve a good anti-erosion effect, and has a good protective effect on gloss retention, chalk resistance, discoloration resistance and delamination resistance. The light stabilizer can be added to the two-component primer and varnish of the automobile; in the wood paint, TINUVIN 123 can be added to the air-drying paint of the alkyd system together with the UV absorber 1130.
