Hostavin® 3315 DISP
Hostavin 3315 DISP is a 52% aqueous dispersion of a benzotriazole UV absorber, designed for UV stabilization of paints and clearcoats. This sustainable UV absorber is characterized by its broad compatibility, high resistance to migration and low extraction, making it particularly suitable for wood and plastics coatings. Hostavin 3315 DISP has been awarded with an EcoTain label resulting from its excellent toxicological profile.
Product Information
- Hostavin 3315 DISP is an easy to use dispersion requiring no milling or dissolving before use and can be incorporated at any stage of the paint production.
- Hostavin 3315 DISP can be used without any impact on the labeling of the final coating formulation. This is particularly important for the Do It Yourself (DIY) consumer market.
- Migration resistance and high thermal stability are key features of Hostavin 3315 DISP to enhance color stability and maintain high gloss in modern coating systems.
Hazards
The product does not require a hazard warning label according CLP regulation (Regulation (EC) No. 1272/2008, as amended).

Hostavin 3315 DISP is recommended for all high performance waterborne coating systems.
For the stabilization of transparent coatings (e.g. wood clearcoats), it is recommended to use Hostavin 3315 DISP in combination with a HALS such as Hostavin 3070 DISP. Both products are benefiting from their low toxicity profile making them EcoTain certified. There is no contribution towards hazardous labeling of customer´s waterborne coating systems when using either Hostavin 3315 DISP or Hostavin 3070 DISP.
Recommended dosage level of Hostavin 3315 DISP: 1.0 - 3.0% (active additive on solid resin)
