1. GENERAL DESCRIPTION
Multi-purpose high temperature ceramic separating and mounting paste.
CRC Metal-Free Paste is a white, metal-free paste, based on high-tech ceramic solid lubricants and matured additives suspended in a mineral/synthetic premium grade stable oil. It is an effective anti-seize formulation for applications from -40°C up to +1.400°C, preventing metal-to-metal contact, seizing, galling and fretting corrosion.
2. FEATURES
Contains no free metals
Reduces friction and wear, even when the base oil has already evaporated
High pressure and high temperature resistance
Protects against burning-in, corrosion and seizing
No galvanic corrosion potential
Fast and easy mounting of threaded parts
Facilitates disassembly of all parts exposed to high temperatures, even after prolonged use in corrosive atmospheres
Stops and prevents disc brake noise and vibration
Hot and cold water resistant
Free from lead, copper, nickel, sulphur and their compounds
Aerosol formulation does not contain chlorinated solvents and uses LPG propellant
3. APPLICATIONS
Machines
Flanges
Disc brakes
Cylinder heads
Threaded parts
Exhaust screw connections
Heat exchangers
Turbines
Fittings
Bolts, nuts, screws
Plugs, shafts, bushings, splines
Pipe joints
4. DIRECTIONS
The surfaces to be treated should be clean, dry and grease-free. Wire-brush scaled parts and clean with an oil-free solvent like CRC Industrial Degreaser.
A thin, even film should be applied either by spraying or by brushing.
Assembled parts can slowly be put in motion.
Avoid mixing with other products.
Test before use on plastics and rubber.
Do not use on energised equipment, oxygen systems or in presence of acetylene.
Use aerosol only in ventilated areas.
A safety data sheet (MSDS) according EU-directive 93/112 is available for all CRC products.
