Hostavin 3070 P is recommended for all types of solventborne coatings. For pigmented system, Hostavin 3070 P can be used alone.
For clearcoat systems, it is recommended to use Hostavin 3070 P in combination with a UV absorber, in the ratio 2:1 to optimize the UV performance of the coating. Depending on the requirements, Hostavin 3206 LIQ, Hostavin 3130 LIQ or Hostavin 3400 LIQ can be used, Hostavin 3400 LIQ being the highest performing UV absorber from the portfolio.

Recommended dosage level of Hostavin 3070 P:                  1.0 - 3.0% (active additive on solid resin)
