Hostavin ARO 8 powder is recommended for low to moderate stabilization requirements. It can be used in most of the solventborne coatings, and is particularly recommended for wood coatings.
To ensure optimal stabilization, clear coats require not only UV absorber but also HALS. Depending on the binder, a traditional HALS, e.g. Hostavin 3055 or Hostavin 3065, or a non-basic HALS, e.g. Hostavin 3058, should be used in combination with Hostavin ARO 8 powder.
