PROBLEM TO BE SOLVED: To provide a coating film defect due to air bubbles and viscosity of a coating material based on a high-purity tetrafluoroethylene resin silicone resin mixed paint having a super water repellency which is stable for a long time and a paint film thereof. In addition, we develop and provide coatings and coatings that can be used for dip coating and brush coating. SOLUTION: In a high-purity tetrafluoroethylene resin-silicone resin mixed paint having a super water repellency stable over a long period of time and a coating film thereof (Japanese Patent Application No. 10-217518), the type and characteristics of the organic solvent are determined by the The range was limited to a range in which few bubbles were obtained. Preferably, a defoaming treatment is performed during the step of preparing the paint. As a result, most of the bubbles in the paint are removed, and the specific gravity change rate in the paint becomes very low. |
