The present fluoropolymer solutions have long shelf stability life, minimal to no formation of insoluble N residue or gel over the period between their manufacture and use, are of a viscosity that allows for facile filtration and so are sub - en. ) stantially 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 sub- strate during use and over the lifetime of the electronic device.
