Applications

Hostavin 3400 LIQ is recommended for coatings requiring superior outdoor performance, i.e. automative OEM clearcoats, high end general industrial and exterior wood coatings, just to name a few applications.

Hostavin 3400 LIQ is a non-migrating UV absorber. When formulated in combination with a non-migrating HALS, such as Hostavin 3058 LIQ or Hostavin 3070 P, this UVA/HALS package will provide outstanding outdoor light stabilization in coatings applied on plastic substrates.

For clearcoats, a combination of Hostavin 3400 LIQ and a radical scavenger (HALS) such as Hostavin 3292 LIQ or Hostavin 3058 LIQ is recommended, depending on the binder chemistry and the stabilization requirements.

For automotive OEM 2K-PU systems a combination of Hostavin 3400 LIQ and Hostavin 3070 P will provide the best results in terms of durability. 

Recommended dosage level of Hostavin 3400 LIQ:             1.0 - 3.0% (active additive on solid resin)
