Paint Primer Layers

Primer coating contamination forms unevenly during exposure to environmental factors, so buildup occurs on inorganic layers and adheres strongly to base materials. Before cleaning, surface exhibits patchy patterns because particles embed into primer matrix. Treatment applies laser energy, and removal achieves selectively without substrate damage. In observations, metal substrates show resilient contamination so challenges arise from heat sensitivity, while composites demand adjusted pulses for uniform stripping. After ablation, layer detaches easily from smooth areas yet resists in crevices. Process removes contamination effectively, and results indicate better adhesion prevention on treated surfaces. Buildup is detected mainly at edges because of primer porosity.
