Laser Coating Removal
Beyond paint, laser cleaning is effective at removing a wide range of industrial surface coatings — powder coatings, epoxy primers, rubber linings, thermal spray coatings, anodising, and more. The mechanism is the same: the coating absorbs laser energy, is ablated or delaminated, and the substrate is left intact. Parameter selection is critical — different coatings have different optical absorption and thermal characteristics.
Coating Types — Laser Removability
Powder coatings
Thermosetting powder coatings on steel and aluminium substrates are effectively removed by pulsed laser. The coating absorbs the laser energy while the metal substrate reflects it preferentially.
Epoxy primers and coatings
Epoxy coatings respond well to laser ablation. Both single-layer and multi-layer epoxy systems can be removed selectively.
Rubber linings and bonded rubber
Industrial rubber linings on metal substrates. Laser ablates the rubber layer and can be used to prepare the substrate surface for re-lining.
Thermal spray coatings
Ceramic and metallic thermal spray coatings can be removed by laser. This is a technically demanding application requiring careful parameter selection to avoid substrate modification.
Anodised layers
Selective removal of anodised layers from aluminium — useful for partial removal prior to repair, bonding, or reanodising specific areas.
Adhesive and sealant residues
Cured adhesives, sealants, and bonding agents on metal substrates. Often used in maintenance and repair workflows where mechanical removal risks substrate damage.
Advising on Coating Removal Applications
Not every coating is straightforward to remove by laser. Success depends on the coating's optical absorption at the laser wavelength (typically 1064–1080nm), the coating thickness, the substrate material, and the acceptable outcome (full removal, partial removal, surface preparation for recoating).
Before specifying a system for coating removal, contact ApexLase with the coating type, substrate, and your target result. Where a demonstration or parameter test is practical, this can be arranged using your own samples.
