True Ablation

The FP-300 doesn't burn paint off — it ablates it. The laser energy is absorbed by the coating, which vaporizes in nanoseconds. The bare aluminum underneath reflects the laser and stays untouched. That's why the FP-300 can remove paint but won't burn paper.

This isn't heat-based removal. It's selective absorption. Contaminants absorb. Metal reflects. No chemicals. No sanding. No contact. Just light.

How Laser Ablation Works

1

Absorption

The laser pulse hits the surface. Paint, primer, corrosion, and organic contaminants absorb the 1064nm wavelength strongly. The energy is concentrated in the coating layer.

2

Vaporization

The absorbed energy causes the contaminant to rapidly heat, crack, and vaporize in nanoseconds. The material is ablated — converted directly from solid to gas — without burning.

3

Reflection

When the coating is gone, bare aluminum reflects the laser light. The energy bounces off instead of being absorbed. This is the built-in safety mechanism — the substrate protects itself.

4

Extraction

Vaporized material is captured by a standard HEPA/activated carbon vacuum extraction system. No liquid waste, no chemical residue, no environmental disposal — just a dry, clean process.

The Paper Test

The simplest demonstration of true ablation: the FP-300 strips paint from a surface but won't burn a sheet of paper held directly in the beam path. The paper reflects the 1064nm wavelength just like bare aluminum — there's nothing to absorb, so nothing happens.

Why Ablation Beats the Alternatives

Every other method either damages the substrate, creates hazardous waste, or both.

Chemical Stripping

  • ×Toxic solvents (methylene chloride, NMP)
  • ×Hazardous waste disposal required
  • ×Worker exposure and PPE requirements
  • ×Environmental compliance costs
  • ×Slow — hours to days per panel
  • ×Can soften or damage composites

Mechanical Sanding/Blasting

  • ×Physical contact risks substrate thinning
  • ×Uneven material removal
  • ×Dust and particle contamination
  • ×Can mask underlying corrosion
  • ×Operator skill-dependent results
  • ×Damages rivet heads and fasteners

Heat-Based Methods

  • ×Transfers heat into substrate
  • ×Risk of warping thin aluminum
  • ×Heat-affected zones change grain structure
  • ×Temperature monitoring critical
  • ×Can weaken heat-treated alloys
  • ×Not suitable for composites
