Fluorine resin coating manufacturing methods and fluorine resin coating

摘要

PROBLEM TO BE SOLVED: To provide a method for producing a fluororesin-coated product having a coating film with excellent surface smoothness without requiring separately a step of vulcanizing a fluororubber and a step of carrying out surface smoothing treatment. ;SOLUTION: The fluororesin-coated product production method is for producing a fluororesin-coated product by applying a coating material composition (A) containing a fusible fluororesin (a1) and fluororubber (a2) to an object to be coated, drying the composition, and then applying a coating material composition (B) containing a fusible fluororesin (b) and baking the resulting object, where the coating material composition (B) is to be applied before the fluororubber (a2) is vulcanized and the baking is carried out at a temperature whose lower limit is a temperature 10°C higher than the higher melting point between the melting point of the fusible fluororesin (a1) and the melting point of the fusible fluororesin (b) and whose upper limit is lower than the lowest temperature among the decomposition temperature of the fusible fluororesin (a1), the decomposition temperature of the fusible fluororesin (b), and the heat resistant temperature of the object to be coated. The fluororesin-coated product has the surface roughness [Rz] of 2 μm or lower.;COPYRIGHT: (C)2003,JPO
