Processing and Safety Guidelines
GP-536 reacts with water, alcohols, or other reactive hydrogen compounds to liberate hydrogen gas. Since the hydrogen is flammable and also will cause pressure build up in closed containers, use all proper precautions when handling these products. Alkaline materials will cause a rapid release of hydrogen when in contact with GP-536, and must be avoided. GP-536 may cause skin irritation. Consult Safety Data Sheet for additional safety information.
GP-536 is supplied in 5-gallon (40 lb.) pails, 55-gallon (440 lbs.) drums and 330-gallon (2640 lbs.) totes.
