    Abstract: A fluoropolymer surface can be adhered to another surface by coating a fluoropolymer surface with a perfluorinated cycloalkane or a solution of a fluoropolymer in a perfluorinated cycloalkane to make a coated fluoropolymer surface, contacting said coated fluoropolymer surface with another surface, and then applying pressure to force said coated fluoropolymer surface and said another surface together, to adhere said fluoropolymer surface to said another surface. The process is carried out at a temperature below the perfluorinated cycloalkane's atmospheric pressure boiling point of 140 DEG C or more.
