The favorite ozone-safe freeze spray from MicroCare, this product features a conductive additive that minimizes static build-up and ice formation on the components.  Widely used in circuit test and repair, techs use this product to find intermittent fault in circuit boards. Chills to lower than -45°F/-43ºC in seconds; may go as low as -60°F/-51°C depending upon ambient conditions. Ultra-pure. Safe on plastics. It will not  leave residues, attack soft plastics or generate the component-shattering thermal shock that can occur with HCFC-based chillers.  The additive evaporates without leaving any residues in about sixty seconds. Nonflammable for maximum safety
