Freeze Spray Circuit Refrigerant 10-oz Aerosol Can RX100 is an inert, high-purity freezing agent which cools instantly, with very little spray. It protects static sensitive devices from potential damage caused by electrostatic charges. Safe to use on most rubber, polymers, and metals. It vaporizes completely, is nonflammable, nonconductive and does not leave a residual film. Uses: Hot-cold intermittent testing of electronic components Rapid detection of defective parts Locating hairline cracks in PCBs Protecting parts during soldering Cold testing of prototype circuits Minimal static voltage generation Freezes small areas to -62ºF (-52ºC) Cools molds quickly; rapid removal of adhesives Features: For fast tracking of thermal intermittents Protector for static sensitive devices.
