| abstract |
Ordinary dispensers may be used to dispense agents containing corrosive components by means of a vehicle medium if the parts of the valve of the dispenser coming into contact with the agent are made of stainless steel or coated with a polyolefine. Such parts are, in particular, valve plates and springs. The agents preferably contain less than 0.5 wt.% of halides (calculated as NaC1). |
