Was ist UV-STABILISATOR-UV-1 CAS 57834-33-0？

UV Stabilizer UV-1 (CAS 57834-33-0) is a highly effective ultraviolet light absorber used to protect polymers, coatings, and plastics from UV-induced degradation. Also referred to as Light Stabilizer UV-1 or Omnistab UV 1, this compound belongs to the benzophenone derivative family and provides excellent light stability by absorbing harmful UV radiation.

UV-STABILISATOR-UV-1 ist der hellgelbe Flüssigkeit mit der Summenformel C17H18N2O2, Molekulargewicht, 282.3, Feuchtigkeit ≤1.0%, Siedepunkt von 188 ~ 190℃/13Pa, relative Dichte: 1.127, Viskosität (20 ° C) von etwa 4752mPa·s, Brechungsindex von 1,64. Löslichkeit: >50 in ethanol, >50 in Isopropylalkohol, >50 in Butylacetat, und null in Wasser. In Bezug auf PU -, UV-1 ist besser als andere anti-UV Agenten, und ist verwendet in schäumenden Materialien, Beschichtungen, Leder und Platten.

It is particularly suitable for transparent and light-colored systems, where long-term protection against discoloration, brittleness, and loss of mechanical strength is critical. As a China UV Absorber UV-1 supplier, we provide consistent quality and competitive pricing for global customers.
