FIELD: impregnation or coating of fibers, porous pieces, fiber glass fabrics and preparation of solutions for metals coating. SUBSTANCE: fluoropolymers water dispersions produced by emulsion polymerization, non processed from melt and film formatting substances during sintering and bearing fluoropolymer (a) with average size of particles (mean value) 180 - 400 nm and fluoropolymer (b) with average size of particles below by factor of approximately 0.3 -0.7, so that dispersion has no monomodal numerical distribution of particles diameter, are useful for impregnation or coating of surfaces, for example, of fibers or sheets of fibers or porous substances and especially - for coating of fabrics of fiber glass an also for preparation of solutions for metals coating. EFFECT: improved process. |
