Abstract
Abstract A fluoroplastic resin dispersion is modified by the addition of a fluoroelastomer latex to yield a fluid coating or casting composition. The fluoroplastic resin dispersion, preferably an aqueous dispersion of a perfluoroplastic, such as ploytetrafluoroethylene (PTFE), is modified by blending with a fluoroelastomer composition, preferably a latex, such that the fluoroplastic comprises up to about 95%, preferably up to about 90%, by weight of the invention composition. The fluoroelastomer component comprises at least about 5% by weight of the blend. The fluid compositions according to the invention may preferably comprise from about 10-95% by weight fluoroplastic and from about 5-95% fluoroelastomer.
