M Chemical GUARD DOG™ UVP Benzotriazole UV Absorber
Categories: Other Engineering Material; Additive/Filler for Polymer

Material Notes: GUARD DOG™ UVP light stabilizer is a derivative of Benzotriazole that has exceptionally strong and broad-range UV absorption properties (UV A 315 -400 nm and UV B 290 - 314 nm) throughout the UV spectrum. It is a highly efficient UV absorber and is recommended for thermoset plastics and coatings that function as ultraviolet screens for photosensitive substrates.

Applications: Extremely effective in Styrenic polymers, PVC, polycarbonate, ABS, unsaturated polyesters, PU, acrylic polymers, natural rubber, synthetic rubber, paints, synthetic fiber, cellulose resin and adhesives.

Performance Benefits:

  • Guard Dog™ UVP performs synergistically when used in combination with Hindered Amine Light Stabilizers (HALS)
  • Very high degree of photostability and resistant to oxidizing and reducing agents
  • High heat resistance (5% wt. loss @ 190°C) without significant degradation or volatility at proper extrusion temperature. Does not discolor during light or heat aging.
  • Excellent compatibility with polymers and is odorless. Does not impart smell to the polymer.

Typical Properties:

  • Free flowing pale yellowish powder
  • Solubility (g/100g @ 25°C): Acetone 3, Benzene 7, Ethyl Acetate 3, Chloroform 13,Toluene 6
  • Max, nm: 344
