Abstract
A method using irradiation with optical light having a wavelength of 160 to 500 nanometers without higher wavelengths with cooling of the surface during the irradiation to modify the surface ( A, A, A, A, A, A) of a substrate ( ) is described. The light is filtered or the lamp ( ) is restricted to the limited range to avoid the affects of the higher spectra. The light can be pulsed or continuous. The method is significantly enhanced by the presence of water ( ) on the surface, preferably also in the presence of ozone in the water. The treated surfaces are more paintable and bondable.
