Abstract
Abstract PCT No. PCT/JP81/00013 Sec. 371 Date Sep. 1, 1981 Sec. 102(e) Date Sep. 1, 1981 PCT Filed Jan. 21, 1981 PCT Pub. No. WO81/02161 PCT Pub. Date Aug. 6, 1981.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.
