Abstract: Aqueous dispersions of fluoropolymers obtained by emulsion polymerization and containing at least one fluoropolymer A) with an average particle size (number-average) of at least 200 nm and at least one fluoropolymer B) with an average particle size (number-average) of not more than 100 nm, one of components A) and B) being a thermoplastic and the other component not being processable from the melt, and the entire dispersion having a non-monomodal number distribution of particle diameter, are suitable for saturating, impregnating surfaces, for example of fibers or sheet-like articles made from fibers or porous materials, in particular for coating glass-fiber fabrics as well as for formulating metal-coating systems.
