Product Description
UV-327 is a benzotriazole type ultraviolet light absorber (UVA), imparting good light stability for plastics and other organic polymers.
Application
UV-327 is recommended in a variety of polymers and organic substrates, including acrylic polymers, polycarbonate, polyesters, styrene homo- and copolymers, unsaturated polyesters, polyvinyl chloride, polyolefins, polyvinyl butyral, elastomers, and adhesives.
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 15kgs net kraft paper bag, 7.5mts onto 20 pallet in 20Fcl, or in 20kgs drum
Storage : Keep tightly closed and store in cool and dry place
Safety Information
Non-hazardous for air, sea and road freight.
