Drips, spills and leaks are common in vulnerable aircraft entryways, galleys, lavatories and cargo compartments. When fluids penetrate unprotected floorboards and cause corrosion, the cost can soar sky high — up to $100,000 per aircraft, in addition to the downtime to install floor panels and replace beams.

The solution: 3M™ Aircraft Corrosion Prevention System, a proven, multi-layer approach that offers lightweight protection. Designed for efficient application and easy inspection, our portfolio of products work together to help reduce maintenance costs, extend service life and enable safer aircraft.
