  • Magnetic coating compositions containing fluoropolyols
    Patent number: 5061577
    Abstract: A class of fluorinated polyols which when added to formulated dispersions used to make a magnetic particle based coating not only improves the dispersion of the particles in the formulation during manufacture but also improves the wear characteristics of the cured coating during use. The fluorinated polyol may be prepared either by the reaction of a diglycidyl ether with a diol or by the reaction of two diols with epichlorohydrin.
