Aqueous Dispersions of Nano Colloidal Antimony Pentoxide Flame Retardant Additives
We offer aqueous Nano colloidal antimony Pentoxide as a synergist with halogenated flame retardants in textiles, adhesives, coatings and water-based systems.
ADVANTAGES OVER CONVENTIONAL ANTIMONY TRIOXIDE SYSTEMS
s Better penetration of the substrate.
s Less pigmenting or whitening effect for deep mass tone colors.
s Easier handling and processing. Liquid dispersions will not clog spray guns.
s Translucency for coatings, films and laminates.
s Easy compounding; no special dispersing equipment required.
s High FR efficiency for minimal added weight or change in hand.
APO are water-based dispersions of nano-sized antimony pentoxide used with halogenated flame retardants to increase their efficiency when used in flame retardant treatments of materials such as textiles, nonwovens, adhesive latices, and coatings.
Antimony Pentoxide (Sb2O5), % by weight: 20-50
PH value: 5-8
Viscosity in centipoise: 5-10
Specific Gravity: 1.35-1.60
The total amount and ratio of flame retardants needed depend upon the severity of the test requirements and the material being treated. In most cases, optimum flame retardant performance in a halogen/antimony system is attained when the halogen and antimony are used at a 3:1 mole ratio. Exceptions are PVC and PVDC latices, which contain high levels of chlorine, so we recommend that the antimony pentoxide be added to your formulation until the complete system passes the required flame test.
STORAGE AND HANDLING
APO Antimony pentoxide sols should be stored in a cool dry area. Shelf life is guaranteed for one year. Mixing in the drum may be necessary if the product is stored for an extended amount of time. See the Safety Data Sheet for specific handling recommendations. Please note that these products should be protected from freezing. Should the product freeze, thaw the material and remix before use.
