Advantages about Antimony Pentoxide Colloidal
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.
