<p>Treatment of FRP surfaces for brief periods of time by exposure to short wavelength ultraviolet light in air, UV/Ozone, increases the adhesive potential of FRPs to polyurethane adhesives. Furthermore, FRP polymer surfaces treated by this process retain more adhesive strength after aging at elevated temperature in the presence of moisture than untreated surfaces or surfaces washed with isocyanate in MeCl2. Epoxy adhesives, also, can be used.</p> |
