LPS 05416 NU Contact Cleaner CFC-Free – 11 oz Non-Flammable for Aerospace Electronics

LPS 05416 NU Contact Cleaner is a non-flammable (NU = non-flammable), CFC-free contact cleaner from LPS — specifically designed for cleaning aerospace electronics, avionics, electrical contacts, and electronic assemblies in environments where flammable contact cleaners create unacceptable fire and explosion risk. In many aerospace maintenance environments — particularly fuel-wetted areas, fuel tank adjacent work zones, aircraft belly work, and enclosed spaces with limited ventilation — the use of flammable cleaning solvents creates serious fire hazard that requires the use of non-flammable cleaning alternatives.

LPS NU Contact Cleaner’s non-flammable formulation uses non-flammable carrier solvents — typically HFCs, HCFCs, or similar non-flammable fluoro-solvent systems — that provide effective electronics cleaning without the fire risk of hydrocarbon or alcohol-based contact cleaners. This makes LPS NU the appropriate choice for avionics cleaning in areas where hot work permits are required or where ignition source control makes flammable cleaner use impractical.

The CFC-free formulation ensures environmental compliance with ozone-depleting substance regulations while maintaining the non-flammable performance characteristic that makes LPS NU suitable for safety-critical aerospace maintenance environments.

Technical Information

LPS NU Contact Cleaner uses a non-flammable fluorinated solvent carrier system — HFCs (hydrofluorocarbons) or similar non-flammable fluorinated solvents — that provide the solvency needed to dissolve common electronic contamination (flux, oils, moisture, dust deposits) while lacking the flammability of hydrocarbon solvents used in standard contact cleaners. The non-flammable solvents in LPS NU have flash points above or no flash point, making them suitable for use in areas where flammable materials are restricted.

The trade-off of non-flammable fluorinated solvents compared to flammable hydrocarbon alternatives is typically in the solvent power and cost — fluorinated solvents are more expensive per volume but provide the critical safety advantage of non-flammability for environments where this property is required. For aerospace maintenance operations in fuel-adjacent zones, this trade-off is clearly justified by the safety risk reduction.

Verify that LPS NU Contact Cleaner’s specific fluorinated solvent system is compatible with the specific plastic and elastomer types in your electronic assembly before full-area application — some fluorinated solvents may attack certain exotic thermoplastics or specialty elastomers not typically found in standard aerospace electronics assemblies.

Frequently Asked Questions

Q: What is LPS NU Contact Cleaner?
A: LPS NU is a non-flammable, CFC-free contact cleaner for aerospace electronics — the non-flammable formulation is used where flammable cleaners create fire or explosion risk in maintenance environments.

Q: MPN for LPS NU Contact Cleaner 11oz?
A: MPN is LPS09416.

Q: What does NU mean in LPS NU Contact Cleaner?
A: NU indicates Non-flammable — the cleaner uses a non-flammable fluorinated solvent system rather than the flammable hydrocarbons or alcohols used in standard contact cleaners.

Q: When should non-flammable cleaner be used?
A: Use non-flammable cleaner in fuel-wetted areas, fuel tank adjacent maintenance zones, enclosed spaces with limited ventilation, and any environment where ignition source control makes flammable cleaner use unsafe.

Q: Is LPS NU CFC-free?
A: Yes. LPS 05416 NU uses a CFC-free formulation — compliant with ozone-depleting substance regulations while maintaining the non-flammable safety performance.
