Polytetrafluoroethylene coatings for glass fabrics

摘要: Coated glass fabric of improved flex life is provided, the coating on comprising (a) unsintered polytetrafluoroethylene having a specific melt viscosity at least 1 × 10 9 poises 380°C. and (b) condensation product polyhydrolyzable compound which tetravalent titanium, zirconium, or tin. The can also contain water repellent additive prevents from soaking into fabric. present either as blend basecoat topcoat be obtained by applying dispersion contains still in state, optionally, additive, to fabric, followed drying without sintering polytetrafluoroethylene.
