  • Patent number: 6565927
    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 (12A, 104A, 202A, 304A, 402A, 502A) of a substrate (12, 104, 202, 304, 402, 502) is described. The light is filtered or the lamp (24, 106, 212, 306, 510) 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 (14, 124, 204, 306, 410, 508) on the surface, preferably also in the presence of ozone in the water. The treated surfaces are more paintable and bondable.

  • Patent number: 6551663
    Abstract: A method for improving the thermal barrier properties of silicone resin/glass fiber composites. Composites comprising a layer of polysiloxane (silicone resin) matrix with a glass or quartz fiber reinforcement embedded in such matrix and an organic polymeric layer were subjected to multi-cycle heat treatment, preferably with quartz lamps. The polysiloxane layer was pre-coated with graphite dispersion in order to ensure acceptable optical receptivity of the polysiloxane layer. As a result, the silicone resin was converted into a thick porous layer of silicone dioxide, the latter having the improved thermal barrier properties.
