Packing Potassium Acetate is supplied in woven lined paper bags or jumbo bag.
Storage and handling Potassium Acetate is hygroscopic. It should be stored and handled in its original packages or in Suitable sealed containers and kept in a clean dry place. Under normal conditions of use potassium Acetate does not present any undue health hazard. Precautions should be taken to prevent entry into eyes and prolonged or repeated skin contact. Exposure to the dust at high concentrations should be prevented by the provision of suitable ventilation.
Application Potassium Acetate is used for the manufacture of antibiotics, potassium penicillinate, and in solutions for haemodialysis and peritoneal dialysis. In addition it can be used as a textile conditioner, a polymerization catalyst and as a catalyst in the production of polyurethane foams and carbon black. It is also used as a dehydrating agent, as runway de-icing fluid or drilling fluid additive.
