CRC MINUS 50 Spray

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 0C to a minimum of -50C; 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.
