Laser paint stripping
is a process involves the rapid heating of coatings
which results in several removal mechanisms
depending on the coating physical and chemical
properties. The most desirable removal phenomenon
is thermo mechanical stress induced dislocations
and then physical ablation. Unlike, abrasive
blasting which have cost associated with the
consumable blast media and disposal, the laser
process only consumables are gas and electricity
and disposal is only the paint dust.
Coatings that are easily removed
include paint, adhesives, epoxies, and heavy rust
or scale. Suitable substrates include plastic,
metal, cloth, stone, ceramic, composites, and
wood. The process is dependent of coating absorption.
Therefore, for the ISL-4000l systems the darker
colors to the infrared wavelength of the laser
are more absorptive and therefore more easily
removed. These colors are black, blue, gray, and
green. The colors that are more difficult to remove
are white, red, orange and yellow.
Nuvonyx is the only direct diode
manufacture that can pulse or laser diode.
