Features & Benefits

Advantages Over Conventional Antimony Trioxide Systems
  • Better penetration of the substrate.
  • Less pigmenting or whitening effect for deep mass tone colors.
  • Easier handling and processing. Liquid dispersions will not clog spray guns.
  • Translucency for coatings, films and laminates.
  • Easy compounding; no special dispersing equipment required.
  • High FR efficiency for minimal added weight or change in hand.

Technical Details & Test Data

Compound Information

NYACOL A1550 aqueous dispersions are supplied at approximately pH 5 or pH 7 and, in nearly all applications, should have the pH adjusted before compounding with any latex. This adjustment assures full utilization of the colloidal particles without agglomeration or latex destabilization. Follow the latex manufacturer's recommendations for the optimum pH. Neutralize using ammonium hydroxide, which will volatilize during the drying and curing of latex film.

NYACOL A1550 Dilute with water to 40% Sb2O5 or less, then neutralize with ammonium hydroxid.
