Useful:

• Uses: DXSORB 405 is mainly used as automotive clear coats; automotive powder clear coats; powder coatings for plastics and wood; high proformance industrial coatings. Tinuvin 405 is a solid triazine-based UV absorber for coatings. It was designed to meet the high performance and durability requirements of acrylic powder coatings for transportation and industrial applications. This light yellow powder is applied in high-performance automotive OEM powder coatings and high-performance industrial powder coatings. For outdoor applications, Tinuvin 405 needs to be combined with a hindered amine light stabilizer (HALS) such as Tinuvin 144 or Tinuvin 152.
