Standard light stabilizer for coatings

Hostavin® 3065 LIQ

Hostavin 3065 LIQ is a 100% liquid low molecular weight hindered amine light stabilizer (HALS). It is a basic HALS characterized by its good solubility, broad compatibility and good stabilization efficiency in a wide range of coating systems.
  • Suitable for solventborne coatings and easy to incorporate into waterborne coatings with the addition of a co-solvent
  • Excellent solubility and broad compatibility in 2K-PU, 1K Acrylics, TSA, Alkyds and Polyesters binder systems 

Classification according CLP regulation (Regulation (EC) No. 1272/2008, as amended).
    Skin sensitization, Cat. 1A
    Acute aquatic toxicity, Cat. 1

    Chronic aquatic toxicity, Cat. 1
For further information please refer to the Material Safety Data Sheet.

Hostavin 3065 LIQ is recommended for solventborne and waterborne coatings, such as automotive OEM coatings, car refinish and general industrial coatings. Hostavin 3065 LIQ is a methylated basic HALS which can impede the crosslinking of binders, particularly acid-catalyzed systems. In such a case, Hostavin 3058 LIQ is recommended as an alternative solution. In clearcoats, a combination of Hostavin 3065 LIQ and a UV absorber such as Hostavin 3206 LIQ, Hostavin 3130 LIQ or Hostavin 3400 LIQ is recommended, depending on the binder chemistry and the degree of stabilization required.

Recommended dosage level of Hostavin 3065 LIQ:               0.5 - 2.0% (active additive on solid resin)
