摘要： The present disclosure relates to a passivation layer comprising a photocrosslinked fluoropolymer and a process for forming the layer. Passivation layers comprising the crosslinked fluoropolymer have low dielectric constants, low water absorptivity and are able to be photoimaged so as to provide the very fine features needed for modern electronic equipment.

摘要： The present disclosure relates to solutions for forming a fluoropolymer coatings, comprising: i) an organic solvent, and dissolved therein ii) a fluoropolymer comprising repeat units arising from specific fluoroolefin, alkyl or aryl vinyl ether and alkenyl silane monomers. The present fluoropolymer solutions have long shelf stability life, minimal to no formation of insoluble residue or gel over the period between their manufacture and use, are of a viscosity that allows for facile filtration and so are substantially free from undesirable submicron size particles, have a dissolved polymer content such that the solutions are of utility in commercial single-coat coating processes, and afford fluoropolymer coatings on substrates that have excellent adhesion to the substrate during use and over the lifetime of the electronic device.

摘要： The present disclosure relates to a photocrosslinkable fluoropolymer coating composition, a coating layer comprising a photocrosslinked fluoropolymer and a process for forming the coating layer. Coating layers comprising the crosslinked fluoropolymer have low dielectric constants, low water absorptivity, good adhesion to conventional electronic device substrates, and are able to be photoimaged so as to provide the very fine features needed for modern electronic devices.
