Abstract
Polytetrafluoroethylene fluorocarbon resin dispersion-containing coatings for glass fibers are disclosed. In one embodiment, the polytetrafluoroethylene fluorocarbon resin dispersion-containing composition also comprises a lubricant and is suitable for use as a padding composition for glass fiber fabric. In another embodiment, the polytetrafluoroethylene fluorocarbon resin dispersion-containing composition also comprises a film-forming polymer, a thixotropic gelling agent, a silane coupling agent and, optionally, a lubricant and is suitable for use as a size composition for glass fibers.
Claims1
A glass fiber fabric coated with the residue formed by removing water from a padding composition consisting essentially of an aqueous dispersion of polytetrafluoroethylene resin and a lubricant selected from a dispersible vegetable oil, the condensation product of dimethylaminopropylamine with pelargonic acid and an amide-substituted polyethyleneamine, wherein the glass fibers of said fabric are sized with the residue formed by removing water from a sizing composition comprising an aqueous dispersion of polytetrafluoroethylene resin, a film-forming polymer, a thixotropic gelling agent and an organo silane coupling agent.
