UV 531 , Tinuvin 531 for ABS resin / polyurethane / phenolic resin , CAS No. 1843 - 05 – 6


Quick Detail :


UV531 protects polymers from UV radiation , helping to preserve the original appearance and physical integrity of molded articles , films , sheets , and fibers .


Description :

  1. Name : UV531
  2. Chemical name : 2 - Hydroxy - 4 - n - octoxybenzophenone
  3. CAS No. : 1843 - 05 - 6

UV531 significantly improves the resistance of clear coatings to failures upon exposure to sunlight such as discoloration , cracking , loss of gloss and loss of adhesion . Its performance in outdoor applications can be improved further by use in synergistic combination with a hindered amine light stabilizer ( HALS ) such as UV292 or UV123 . Use of UV 531 should be reserved for applications where expectations of the final coating’s durability are moderate since the light stability of 2 - hydroxy - benzophenone derivatives is known to be limited .


Applications :


UV531 is an effective light stabilizer for a variety of plastics and other organic substrates such as polycarbonate , PE , PVC , ABS resin , polyurethane , phenolic resin , paraffin and rubber .
