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)
Packaging and Handling
Plastic drums 25 kg
Pallet 300 kg (12 drums)
Hostavin 3070 DISP can be stored for at least three years from the date of shipping when kept cool and dry in the original sealed containers. Storage temperatures above +40°C and below +4°C should be avoided. Hostavin 3070 DISP should always be well stirred prior to use, as a slight sedimentation might occur over time.
