Antimony Pentoxide colloidal Sb2O5 widely used as flame retardant additive
Colloid Antimony Pentoxide
Synonyms: Antimony Pentoxide Colloidal,Aqueous Colloidal Antimony Pentoxide
Molecular formula: Sb2O5·nH2O Appearance: Liquid stat, milk-white or light yellow colloid colloidal solution
Stability: Very High
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.
