Product Description

Lear Chemicals Corrosion Preventer

ACF-50 Corrosion Preventer

ACF-50 Anti-Corrosion Formula is a state-of-the-art anti-corrosion lubricant compound, specifically designed for the Aerospace industry. ACF-50’s unique chemistry offers excellent penetration, coupled with an unmatched 24 months of “active” corrosion protection. Designed specifically to perform as both a Corrosion Inhibiting Compound (CIC) and a Corrosion Prevention Compound (CPC). ACF-50’s blend of non-flammable, non-toxic, polar bonding inhibitors and moisture-displacing additives penetrate deep into corrosion cells to actively remove electrolytes. No longer in contact with the metal surface, these electrolytes evaporate. ACF-50’s resulting dielectric fluid film acts as an “off-switch” for the corrosion process.

  • Complete anti-corrosion solutions for airframe, avionics and ground support equipment
  • Significantly reduces corrosion events in both structure & avionics
  • Ultra-thin film promotes weight reduction, improving payload capacity
  • Non-toxic according to EPA/OSHA standards
  • VAC compliant worldwide

Corrosion Block

Corrosion Block is a unique product that has the ability to both prevent and stop active corrosion in more places than any other product of its type. Corrosion Block uses polar bonding to attach its molecules to ferrous or non-ferrous metals, a microscopic thin film (less than .0004 of an inch) layer is established that is totally hydrophobic and will not conduct electricity (dielectric to 40kV).

  • Clean, clear ultra-thin fluid
  • Non-greasy atmospheric barrier
  • Spray directly into electrical connections
  • Prevents corrosion induced failures
