Technical information


CORR-EX LCP-177 is a proprietary non-flammable ultra thin film lubricant with anti-corrosion properties that when applied forms a “self healing” non-hardening or cracking coating that is approximately 7 microns (0.00028 inch) in thickness thick that is inert and will not increase or decrease contact resistance.

CORR-EX LCP-177 conforms in all respects to MIL DTL-87177B.

CORR-EX LCP-177 lubricant and corrosion preventative compound is formulated without sulphates, chlorides or halogens and is unexcelled in preventing corrosion deterioration on all surfaces of electronic and electrical equipment as well as all metals and alloys and mechanical close-tolerance low speed or light loaded moving components.

CORR-EX LCP-177 contains proprietary water displacing and anti-corrosive compounds that provide a superior lubrication coefficient and protect components against general and fretting corrosion, surface static electricity, corona, and other electro migration problems.

CORR-EX LCP-177 prevents the corrosive damage to electronics and other surfaces caused by exposure to the Sulfur Dioxide (SO2), Nitrogen Dioxide (NO2), Hydrogen Sulfide (H2S), Ammonia (NH3), Chlorine based gases (CL12) based gases in Class III mixed gas tests as well as the thermal decomposition by product of HFC-227ea used in fire suppression systems, Hydrogen Fluoride (HF). CORR-EX LCP-177  will not, however, remove corrosion from or repair an already corroded component or substrate.

LCP-177 is inert and will not increase or decrease electrical contact resistance and will not interfere with any electronics, but it will inhibit corrosion deterioration on all surfaces of electronic and electrical equipment including electrical contactor’s, connectors, and printed circuit boards as well as all metals and alloys. LCP-177 ’s superior lubrication and corrosion protection will protect components against moisture, wear, general and fretting corrosion, surface static electricity, corona, and other electro migration problems.

CORR-EX LCP-177 has the following combination of properties:
• Displaces both fresh and salt water moisture
• Non-toxic and Non-flammable
• Has a decomposition temperature of 550°F
• Will not freeze or harden, retains properties even in high altitude applications
• Is extremely resistant to air-drying
• Self healing
• Does not attract contaminants
• Is inert and will not increase or decrease contact resistance
• Eliminates surface static electricity, Corona and other electro migration problems
• Protects against wear, moisture, general and fretting corrosion.
• Non-reactive to most plastics

Shake aerosol cans prior to use. Stir bulk material prior to use and keep closed when not in use. CORR-EX LCP-177  is non-reactive to most plastics however do not use on Styrene or Polystyrene. Clear plastic surfaces (windows, ports, etc.) should be masked off before applying CORR-EX LCP-177  to prevent any possible fogging or cracking by the solvent carrier.

CORR-EX LCP-177 is available in following containers:
16 oz, (12 oz net), aerosol cans (12 per case)
1 and 5 gallon cans
30 and 55 gallon drums
