Ammonium fluoborate Description
Properties: Clear crystals or needle-like colorless crystals. The relative density is 1.85. Soluble in water, the aqueous solution is weakly acidic. Insoluble in alcohol. It decomposes when heated above 110°C, and sublimes when heated strongly.
Uses: Used as a catalyst for resin finishing in the textile industry. As a gas flux to provide an inert atmosphere. It can also be used as flux for lead brazing. It can also be used as flame retardant and chemical reagent.
Packing: Woven bag or cardboard drum covered with polyethylene plastic bag, net weight 25kg.
Storage and safety protection: Store in a cool, ventilated and dry warehouse to prevent sun and rain
