Epoxy Resin Deposits

Epoxy residue differs from inorganic contaminants so laser cleaning faces unique challenges. Formation occurs during adhesive curing and leaves sticky layers on metal surfaces. These layers bond tightly because of polymer chains. Removal demands precise pulses to avoid substrate damage. After exposure, residue hardens unevenly on composites and resists ablation. So, multi-pass treatments apply for complete elimination. Surface exhibits residue patches during inspections. Buildup forms irregularly on polymers because heat alters epoxy flow. Cleaning achieves better results on metals yet struggles with flexible materials. Process removes organic films effectively in observations.
