Application
UV absorber UV-1 is a liquid formamidine type ultraviolet absorber, it has a very strong UV absorption spectrum peak between 300-330nm, in this region polyurethane is susceptible to radiation degradation. So it has excellent light stability to microporous polyurethane products such as foam, integral skin foam, traditional foam, semi-rigid, soft foam, fabric coating, some adhesives, sealants and elastomers.It is convenient to use and miscible with polyester polyol and polyether polyols, has high solubility in many solvents, and has good compatibility with isocyanates and other polyurethane additives(such as light stabilizer 292).In polyurethane,normal usage level range is 0.2-1.0%.In adhesives and sealant,concentration level normally range is 0.5-1.0%.
