                              Product Description

                              1. GENERAL DESCRIPTION

                              Coolant for electrical and electronic use. CRC Minus 50 is a non-flammable, inert dry coolant spray for maintenance, trouble shooting and repair. Used to cool down parts and components to temperatures below 0°C to a minimum of -50°C; the tracking of intermittent faults, the detection of hairline cracks, and the locating of defective components becomes easier.

                              2. FEATURES

                              • Protects heat sensitive components from high temperatures during soldering and desoldering.

                              • Facilitates precision fitting of metal parts : a short spray will shrink one part so a slip fit becomes possible.

                              • Saves maintenance cost and downtime.

                              • Non-flammable and inert.

                              • No chemical attack of components.

                              • Evaporates completely, leaving no residue.

                              • Invaluable for testing thermostats and all systems responding to temperature changes.

                              3. APPLICATIONS

                              • 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.

                              4. DIRECTIONS

                              • 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 circuitry.

                              • Use extension tube for precise aiming and hard to reach areas.

                              • A safety data sheet (MSDS) according EU directive 93/112 is available for all CRC products.

                              Note :

                              with sensitive or stressed plastic parts, the thermal stress induced by strong local cooling must be considered.
