  • Patent number: 5863608
    Abstract: A method for preparing a castable amorphous fluorocarbon coating upon the surface of a substrate which includes the steps of initially depositing a film of a fluorocarbon having a thickness between about 1500 .ANG. and 50,000 .ANG., and thereafter applying a second coating as a coverlay upon the initial film. Both the initial film and the castable coating consist of an amorphous fluorinated (ethylenic-cyclo oxyaliphatic substituted ethylenic) copolymer having the structural repeating unit: ##STR1## wherein "m" and "n" represent integers providing a molecular weight of between about 230,000 and 500,000, with the relative values of "m" and "n" providing a copolymer with a glass transition temperature ranging from between about 160.degree. C. and 240.degree. C.
