Silicone Sealant Buildup Contamination

Silicone-buildup forms from polysiloxane sealants, applied in construction and automotive coatings, where residues cure into thin, flexible films over time. This contamination distinguishes itself with hydrophobic nature and strong adhesion, unlike oily greases that smear easily, and it persists stubbornly on metals like steel and aluminum, altering wettability without deep penetration. Removal challenges stem from chemical inertness, thus solvents often fail, but laser cleaning succeeds, as targeted pulses ablate the layer precisely and restore surface integrity.
