  • Flame-retardant synergist for use in textile, tissues, paper, paints and in all applications where water is acceptable.
  • Fine particle size provides more efficient flame retardant characteristics than standard Antimony Trioxide grades.
  • Stability and low viscosity of the suspension offer practical advantages.
  • Due to the very fine particle size (less than the wavelength of light), the product has a lower tinting strength than standard Antimony Trioxide.
