Title:
WATER-BASED COMPOSITION, AND METHOD FOR PRODUCING LAMINATE USING WATER-BASED COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2024/075610
Kind Code:
A1
Abstract:
Provided is a water-based composition which contains a tetrafluoroethylene-based polymer, is capable of forming a shaped article having excellent properties including heat resistance and electrical properties (low coefficient of linear expansion, low permittivity, low dielectric loss tangent, and low transmission loss), also having uniformity in film thickness and chemical composition, and also having excellent laser processability, and has excellent handling properties and re-dispersibility after long-term storage. The water-based composition comprises particles of a tetrafluoroethylene-based polymer, a polyamic acid, a water-soluble polyol and water, in which the content of the particles of the tetrafluoroethylene-based polymer is 30% by mass or more.
