Testing Laser Ablation of Momentive’s Silicone Sealants for MRO Applications

SPONSORED BY:

Momentive’s silicone sealants are commonly used in industries where maintenance, repair and overhaul (MRO) is needed and may require the removal of the silicone sealants. Typically, this will involve manually scraping and solvating the sealant, a tedious and cumbersome process, that can also cause silicone contamination. A better alternative to scraping and solvating a cured silicone sealant is laser ablation. This involves emitting light in the nanometer wavelengths at high wavelengths and, with enough power, the laser can raise the temperature of the silicone so rapidly that it will vaporize the sealant while minimal heat is absorbed by the substrate.
