When the sheet of this compressed gas spray falls on one that ... Is 1 to 80% iso-butane as a main component, which is rather less than optimal for a good "compressed air" spray, since the vapor pressure at 20 ° C is about 3 bar. Pure propane is much better suited with 8 bar pressure and the doses it must not be appreciably more stable. 2. 1,3-butadiene is included, though only up to 200ppm (0.02%), but it is a carcinogen and has a narcotic.

Of course, it is combustible, but that is containing all KW sprays. Alternatively, you can put on CO2 or HFCs such as R134a or R218. However, HFCs are very harmful to the climate. CO2, however, should not be used for electronic components. High humidity and / or moisture on circuits produced carbonic acid, which acts korosiv.
