1510023 Coating compositions of fluorocarbon polymers E I DU PONT DE NEMOURS & CO 3 April 1975 [3 April 1974] 48113/77 Divided out of 1510022 Heading C3V A coating composition for use in providing non-stick cookware consists of (a) at least one polymer of one or more ethylenically unsaturated monomers fully substituted with fluorine or a combination of fluorine and chlorine (b) a compound of Co, Fe, Bi, Ce or Mn which decomposes at 100‹ to 500‹ C. to give an oxide or hydroxide, (c) a pigment (d) a liquid carrier and optionally a polymer of one or more ethylenically unsaturated monomers which depolymerizes below the decomposition temperature of (a), a flow control agent, a plasticizer, a surfactant and/or a coalescing agent. The composition exemplified contains PTFE, a terpolymer of ethylacrylate, methylmethaorylate and methacrylic acid, TiO2 cerium nitrate, toluene and water. |
