Abstract
It has been discovered that if a selected water-soluble aluminum, magnesium or zinc salt of a monovalent anion is added to an aqueous dispersion of a non-melt-fabricable tetrafluoroethylene polymer wherein the dispersion has a pH of 4 or less, the resulting dispersion will flow well on a woven fabric substrate, such as a woven glass fiber fabric, and will fill and cover the interstices of the weave without the necessity of having filler particles present.
