Where these two actually differ

  • We flag Volatile organic compound (VOC) emissions, Coating degradation and microparticle shedding, Respiratory sensitization and irritation and Skin and eye contact hazard on the and not on the Nikwax.
  • We flag Respiratory irritation or fume inhalation during application and PFAS in water repellency treatment on the Nikwax and not on the .
  • The is Proprietary fabric guard coating, likely silicone or acrylate-based polymer where the Nikwax is wax-based waterproofing, which is most of the difference in these two grades.
  • The gap is 25 points, wide enough that this is not a close call, and the Nikwax is the one to buy.
  • We are less certain about the grade, at 35% confidence against 78%, because it discloses less.
