PURPOSE:To provide the titled composition giving a coating film driable without causing cracking and having excellent surface smoothness after baking, and suitable for the coating of iron, metals, etc., by adding methyl cellulose to an aqueous dispersion of a thermoplastic fluororesin. CONSTITUTION:The objective composition is obtained by compounding (A) an aqueous dispersion of a thermoplastic fluororesin (e.g. tetra-fluoroethylene/perfluoroalkyl vinyl ether copolymer) with (B) 2-10wt%, based on the thermoplastic fluororesin, of a methyl cellulose (e.g. hydroxypropyle methyl cellulose having a thermal gelatinization temperature of 60-70 deg.C). |
