ABSTRACT:
Aqueous dispersions of fluoropolymers which are obtained by emulsion polymerization, are not processsable from the melt and form a film on sintering, which comprise a fluoropolymer A) having an average particle size (number average) of from 180 to 400 nm and a fluoropolymer B) having an average particle size which is lower by a factor of from about 0.3 to about 0.7, so that the total dispersion has a non-monomadal number distribution of the particle diameter, are suitable for soaking, impregnating or coating surfaces, for example of fibers or planiform articles of fibers or porous materials, in particular for coating fiberglass fabrics, and also for the formulation of metal coating systems.
