Hostavin™ N 30 P
Hostavin N 30 P is an oligomeric hindered amine light stabilizer (HALS) in powder form. It combines a high molecular weight with broad compatibility, excellent resistance to migration and very low volatility. As a non-hazardous, label-free HALS, it is suitable for a wide range of applications, including polyolefins, styrenics, PA, POM, PBT and PVC, as well as automotive OEM, refinish, general industrial, wood and UV-cured coatings.
Product Information
- Highly effective light stabilizer with excellent thermal and color stability
- Excellent hydrolysis resistance and lower sensitivity to acidic environments
- OIT booster when combined with phenolic AO
- Enhanced color stability and high gloss retention for exterior coatings
- This non-migrating and non-extractable HALS is an ideal partner for high performance coatings which require long lasting effects
- Excellent thermal stability, e.g. for powder coating systems
- Good overall solubilities in commonly used organic solvents
- Hazards-free and label-free HALS (no pictograms)
The product does not require a hazard warning label according CLP regulation (Regulation (EC) No. 1272/2008, as amended).

Hostavin N 30 P is recommended for light stabilization of polyolefins, styrenics, PA, POM, PBT, PVC, etc.
In addition to its role of light stabilizer, Hostavin N 30 P offers a pronounced contribution to the long-term heat stability of polymer products.
With his low basicity, Hostavin N 30 P ensures an improved resistance to chemical attacks by e.g. agrochemicals, pesticides, acid rains, etc. It is highly suitable for agricultural applications, e.g greenhouse films or silage films.
Hostavin N 30 P is recommended for all types of solventborne coatings. For pigmented system, Hostavin N 30 P can be used alone.
For clearcoat systems, it is recommended to use Hostavin N 30 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 or Hostavin 3400 LIQ can be used, Hostavin 3400 LIQ being the highest performing UV absorber from the portfolio.
Recommended dosage level of Hostavin N 30 P: 1.0 - 3.0% (active additive on solid resin)
