Hostavin 3055 LIQ can be used in solventborne and solventless coatings. Depending on the requested UV stabilization, the addition rate should be in the range of 1.0 to 3.0%, calculated in active UV stabilizer on solid binder content. As a non-substituted HALS, Hostavin 3055 LIQ is slightly basic and may have an influence on the crosslinking of binders. In such a case, it is recommended to use Hostavin 3058 LIQ as a suitable alternative.
In addition, for an optimized UV stabilization of clearcoats, it is recommended to combine Hostavin 3055 LIQ with a UV absorber, e.g. Hostavin 3206 LIQ or Hostavin 3400 LIQ.
