Polyethersulfone dispersion is based on high-performance PES and emulsified by a special process. It has excellent hardness, corrosion resistance, and flexibility. It is strongly recommended for water-based single-layer Teflon coating. Polyethersulfone dispersion, miscible with water in any proportion, has excellent adhesion, temperature resistance, and corrosion resistance. It is widely used in Teflon coating, enamelled wire paint, and other high-temperature-resistant coatings.
