Aerospace Sealant Residue

Aviation sealants build up as tough, organic residues on aircraft surfaces. They form irregular patterns, oozing into joints and crevices during assembly. This creates sticky layers that harden unevenly, often cracking along edges. In practice, these contaminants cling tightly to metals like aluminum, resisting wipes and solvents.

Laser cleaning tackles this head-on. Pulses target the sealant without harming the base material. On composites, though, removal demands careful control to avoid delamination. Turns out, the key point lies in dialing in pulse energy for clean finishes. Overall, this method clears contamination effectively while maintaining structural integrity.
