Abstract
(EN)
[Problem] To provide a dispersion which comprises a polar solvent and, dispersed therein, a powder including a tetrafluoroethylene-based polymer and which is excellent in terms of dispersibility and the property of forming layers (coating films). [Solution] A dispersion which comprises a powder including a tetrafluoroethylene-based polymer, a polar solvent, and a dispersant, the powder being dispersed in the polar solvent, wherein the dispersant is a polymer which comprises a unit based on a monomer having a fluoroalkyl group and a unit based on a monomer having an oxyalkylene glycol group and which has a fluorine content, an oxyalkylene group content, and a hydroxyl value of 10-50 mass%, 5-75 mass%, and 10-100 mg-KOH/g, respectively.
