Claim 1
Independent Claim
104 words
A METHOD FOR APPLYING A THERMOPLASTIC POLYMER OF TRIFLUOROCHLOROETYLENE TO A CURVED SURFACE WHICH COMPRISES PLACING A LAYER OF A THERMOPLASTIC COMPRISING A POLYMER OF TRIFLUOROCHLOROETHYLENE HAVING A NO STRENGTH TEMPERATURE VALUE BETWEEN ABOUT 220* C., AND ABOUT 350* C. ON SAID SURFACE, HEATING SAID SURFACE TO A TEMPERATURE BETWEEN ABOUT 360* F. AND ABOUT 625* F., AND AFTER INITIALLY HEATING SAID SURFACE TO THE DESIRED TEMPERATURE WITHIN THE AFOREMENTIONED TEMPERATURE RANGE APPLYING A COMPACTING PRESSURE ON SAID THERMOPLASTIC LAYER SUFFICIENTLY HIGH TO BRING IT INTO INTIMATE CONTACT WITH SAID HEATED SURFACE FOR A TIME SUFFICIENT TO PERMIT SAID THERMOPLASTIC LAYER TO ADHERE THERETO.
