  • Fluorinated resin coating composition containing micaceous iron oxide
    Patent number: 4409354
    Abstract: The present invention relates to a fluorinated resin coating composition comprising (a) a fluorinated resin, (b) micaceous iron oxide and (c) a liquid carrier. When the composition of the invention is used as a primer, an auxiliary agent for adhesion is necessitated as the supplemental component in addition to the components (a), (b) and (c). The composition of the invention can afford an excellent wear-resistance and is especially suitable for coating of inner surfaces of cooking utensils. The scratch-resistance of the coating film formed on a cooking utensil is greatly improved especially when the composition is employed for top coating. Sufficient improvement can be also attained in case of using the composition of the invention as a primer.
