Additive solutions for powder coatings in building and construction -
heat and light protection for a longer service life

For metal surfaces that have to be particularly tough, powder coatings are often used (which also do not require solvents and thus have the further advantage of not emitting volatile organic compounds). Clariant provides powerful additive solutions to make sure these coatings stay tough, even if the going gets rough! They are usable for a broad range of powder resins, such as polyester or polyester/epoxy binders and usable with Primid® products. The additives comprise not only light stabilizer solutions, but also antioxidants, thus preventing gas fading and thermal yellowing of powder coatings. 


  • Hostavin® 3051 P
    Hostavin 3051 P is a non-substituted hindered amine light stabilizer (HALS) powder, with enhanced tribo effect for powder coating applications. It also offers good solubility and broad compatibility in all kind of solventborne paint systems.
  • Hostavin® 3070 P
    Hostavin 3070 P is an oligomeric HALS in powder form, with a high molecular weight, excellent resistance to migration and very low volatility. It has a unique profile as a non-hazardous, label-free HALS. Hostavin 3070 P is suitable for many applications such as automotive OEM, refinish, general industrial, plastic, wood and UV cured coatings.
