Description Non CFC ozone safe propellant. It may not be obvious, but many circuit problems occur when flux and other contaminents (even finger prints) remain on the PCB causing 'leakage' between tracks. If you work with RF, high impedance (i.e. FET Op-Amps etc), ioniser or other circuits, PCB cleanliness is a MUST. The electronic circuit board cleaner is a spray that dissolves flux residues & grime leaving the track work and board absolutely clean. We then recommend you 'tropicalise' the board with circuit board lacquer. Specifications DG UN Number : 1268 DG Class : 3 DG Pack Group : II - Medium Danger DG Hazardous Chemical Code : 3YE DG C.A.S.
