Automotive Undercoating

Undercoating-contamination, this organic residue forms unique patterns on surfaces. It accumulates in layered films and irregular deposits, especially under protective coatings. Formation occurs gradually, as residues bond tightly with substrates, thus creating adhesion challenges. In laser cleaning applications, removal proves difficult; contamination resists ablation due to its dense structure and thermal stability. Material-specific behaviors emerge clearly—on metals, it spreads unevenly and absorbs energy poorly, so cleaning demands precise pulse control. After treatment, residue fragments scatter, yet stubborn patches persist in crevices. This contamination, it alters surface texture and demands multi-pass strategies for complete elimination. Process applies laser energy, thus breaks bonds and ejects particles. Challenges arise from re-deposition risks, following initial exposure. Efficiency improves with adjusted parameters, surface already shows reduced residue buildup.
