Abstract
PURPOSE: To provide the titled ring excellent in sealability at a closed position, lubricity at an open position and stick slip resistance, by coating the surface of a synthetic rubber ring with a paint which comprises a fluororubber, a fuororesin, an aminosilane compound and a liquid carrier followed by curing.
CONSTITUTION: For instance, into an encircling recess 5 provided at the bottom of a valve 2 of a vacuum valve is fit a synthetic rubber O-ring 6 whose surface is coated with a paint comprising a fluororubber, a fluororesin (e.g., polytetrafluoroethylene), an aminosilane compound (e.g., γ-aminopropyltriethoxysilane), a liquid carrier and, if necessary, an amine compound (e.g. ethylenediamine), and then cured. The O-ring 6, when the valve 2 is at an open position, slides back and forth with the valve 2 on the surface of the valve seat 1C, and when the valve 2 is at a closed positioned it seals tightly a gap between the valve seat 1C and the valve 2.
