Application
UV-326 is a benzotriazole type ultraviolet light absorber (UVA), imparting good light stability for plastics and other organic polymers. UV-326 is especially suited for polyolefins and cold cured polyesters. It protects polymers from UV radiation helping to preserve the original appearance and physical integrity, especially for polyolefins and polyester resins.
Recommended application and dosage:
1. Unsaturated Polyester: 0.2-0.5wt% based on polymer weight
2. PVC:
Rigid PVC: 0.2-0.5wt% based on polymer weight
Plasticized PVC: 0.1-0.3wt% based on polymer weight
3. Polyurethane: 0.2-1.0wt% based on polymer weight
4. Polyamide: 0.2-0.5wt% based on polymer weight
Packing and Storage
Packing In 25kgs net carton
Storage Keep tightly closed and store in cool and dry place
Safety Information
Non-hazardous for air, sea and road freight.
