ACX powder quickly and efficiently neutralises concentrated acid spills. The neutralisation reaction generates harmless gases and for maximum safety, ACX contains an indicator system that will show when the spill is completely neutralised. Once the chemical has been neutralised the powder can be disposed off as general waste. Water should be used to dilute before attempting to neutralise some concentrated acids e.g. hydrofluorosilic, phosphoric and sulphuric acids. Weight 22.7kg pail.
