Coolant for electrical and electronic use. CRC MINUS 45 is a non-flammable (Directive 2008/47/EC)*, inert dry coolant spray for maintenance, trouble shooting and repair. Used to cool down parts and components; the tracking of intermittent faults, the detection of hairline cracks, and the locating of defective components becomes easier.
- Low Global Warming Potential (GWP)
- Non-flammable (according to directive 2008/47/EC)
- Protects heat sensitive components from high temperatures during soldering and de-soldering.
- Facilitates precision fitting of metal parts: a short spray will shrink one part so a slip fit becomes
- Saves maintenance cost and downtime.
- No chemical attack of components.
- Evaporates completely, leaving no residue.
- Invaluable for testing thermostats and all systems responding to temperature changes.
- Testing of thermometers and thermostats.
- Locating defective electrical parts.
- Finding faulty connectors …
- Locating defective diodes , transistors …
- Shrink fitting / removal of bushes, bearings, spindles …
- Assembly / disassembly of tolerance equipment.
- Checking of transistor ignition systems.
- Trimming / machining of rubber bushes …
- Removal of chewing gum, adhesives, sweets … from fabrics, curtains, carpets, chairs, etc (spray until gum is brittle and then break away).
- Pre-cooling “dental” instruments.
- For use on energized equipment keep ambient temperature under 28°C.
- Let suspect circuit heat-up, spray one component at a time. Spraying of faulty component will give instantaneous change of output.
- Hairline cracks in PC will be exposed by frosting up the copper
- Use extension tube for precise aiming and hard to reach areas.

‘Although classified as nonflammable by GHS, DOT, IATA and IMDG and as measured by ASTM E-681 and ISO 10156, Solstice® Propellant (HFO- I 234ze) can exhibit vapor flame limits at elevated temperatures. Solstice® Propellant has a very narrow flammable range (LFL-UFL) of 8.0-8.5 volume percent in air at one atmosphere under the following conditions:
- Temperature is 86°F (30°C), (and)
- Relative Humidity ?50%, (and)
- High energy ignition source or open flame is present
Accordingly, CRC recommends that for use on energized electrical equipment the ambient temperature should be below 28°C.
