    Abstract: 1286318 Coating glass surfaces with fluorocarbon resins CORNING GLASS WORKS 18 Nov 1969 56269/69 Heading B2E [Also in Divisions B5 and C1] A fluorocarbon resin is bonded to the surface of a silicate glass substrate, e.g. an alumino silicate or borosilicate glass, by (a) cleaning and. drying the glass surface to leave the surface with free available silanol groups (b) treating the cleaned glass surface with a solution of a coupling agent which is an amino-functional silane containing one terminal portion which is reactive with the silanol groups on the glass surface and a second terminal portion which contains a functional amino group, (c) applying a fluorocarbon resin, e.g. polytetrafluoroethylene or a fluorinated ethylene-propylene copolymer to the treated glass surface and (d) heat treating the resin to couple it to the coupling agent at an elevated temperature below that at which the resin degrades rapidly. The coupling agent may be N-beta-aminoethyl-gamma-amino propyltrimethoxy silane, N - beta - aminoethyl - (alpha - methyl - gamma - aminopropyl) dimethoxymethyl silane or gamma-aminopropyltriethoxysilane, suitable solvents for applying the coupling agent as a solution to the glass surface being toluene, benzene, xylene and/or a higher boiling hydrocarbon. The glass surface may be cleaned by heating to 500‹C to oxidize any organic matter present, by treating with 50% nitric acid solution at 80-100‹C. washing and drying with acetone or by alternately dipping in a 50% hydrofluoric acid -50% sulphuric acid solution ad nitric acid bath, rinsing in hot nitric acid at 80-100‹C and rinsing in boiling water. Particularly dirty glass may first be washed in boiling detergent solution, rinsed with water and placed in nitric acid solution. Drying may be effected in an oven at 100‹C for 24 hours or at 400‹C for for 15 minutes. Solution containing 0.1-5% by weight of the coupling agent may be used which may be applied by dipping or by a refluxing technique. The treated surface may then be heated to 60‹-140‹C. The fluorocarbon resin may be applied in the form of an aqueous dispersion which may contain a wetting of agent by dipping or spraying and then dried at 90-120‹C and heated at 260‹C. Heating may be effected at temperatures up to 400‹C.
