M Chemical GUARD DOG™ UV5411 Benzotriazole UV Absorber, Powder and LD Pellet
Categories: Other Engineering Material; Additive/Filler for Polymer

Material Notes: GUARD DOG™ UV5411 light stabilizer is a derivative of Benzotriazole that has exceptionally strong and broad-range UV absorption properties throughout the UV spectrum. It is highly recommended for thermoset plastics, organic substrates and coatings that function as ultraviolet screens for photosensitive substrates. It helps to preserve the original appearance and physical integrity of polymeric systems during outdoor weathering.

Applications: Extremely effective in unsaturated polyesters (0.2 - 0.5 wt%), PVC, styrenics, acrylics, polycarbonates, PU (0.2 - 1 wt%), polyamide (0.2 - 0.5 wt%), PVB, PMMA, PE and elastomers.

Performance Benefits:

  • Strong and broad absorption of UV light in 300 - 400 nm range with low color contribution
  • High degree of inherent light stability and has low volatility
  • Excellent compatibility with polymers and exceptional UV protection for PC and engineering polymers.

Typical Properties:

  • White crystalline free flowing powder
  • lambda MAX, nm: 346
  • Solubility (g/100g @ 25°C): Benzene 65, n-Butyl Acetate 245, Methylene Chloride 70.9, Styrenics 49.7, Xylene 50

Available Properties
  • Specific Gravity
  • Molecular Weight
  • Absorption Coefficient, 10 mg UV/l of Toluene
  • Melting Point
