Title:
AQUEOUS DISPERSION AND METHOD FOR PRODUCING LAYERED PRODUCT USING AQUEOUS DISPERSION
Document Type and Number:
WIPO Patent Application WO/2024/053553
Kind Code:
A1
Abstract:
Provided is an aqueous dispersion containing a tetrafluoroethylene-based polymer, the aqueous dispersion being capable of giving shaped objects excellent in terms of properties such as heat resistance and electrical properties (low coefficient of linear expansion, low permittivity, and low dielectric loss tangent) and of evenness in film thickness and composition, and being excellent in terms of dispersion stability and handleability and having reduced unevenness in composition. The aqueous dispersion comprises particles of a tetrafluoroethylene-based polymer, an alkaline electrolyte, a surfactant, an acidic resin, and water and has a pH in the range of 6-10, a zeta potential less than -30 mV, and an electron conductivity of 0.01-0.2 mS/cm.
