Hostavin 3070 DISP is recommended for all high performance waterborne coatings. 

The increasing use of plastic coated parts in the automotive industry requires the use of Hostavin 3070 DISP to prevent migration issues, leading to improvements in both adhesion and durability. 

Due to Hostavin 3070 DISP polymeric structure, it is a key component in preventing color fading for highly pigmented acrylic based facade coatings.

For pigmented wood coating applications, Hostavin 3070 DISP can be used alone.  For clearcoat applications, it is recommended to use Hostavin 3070 DISP in combination with a UV absorber such as Hostavin 3326 DISP or Hostavin 3315 DISP.

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