METHOD OF PREPARING AMORPHOUS FLUOROCARBON COATINGS

摘要

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 A DEG and 50,000 A DEG , 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-cyclooxyaliphatic substituted ethylenic) copolymer having a molecular weight ranging from between about 230,000 and 500,000.
