WP-425
Durle® WP-425 Polyethersulfone (PES) Dispersion is prepared from polyethersulfone material. Coatings made from this product exhibit excellent hardness, corrosion resistance, and film flexibility. It has wide applicability and demonstrates outstanding adhesion to various substrates.
Key features include:
1. Exceptional thermal stability and high-temperature anti-yellowing properties, making it widely suitable for various light-colored, high-temperature resistant coatings.
2. Outstanding flexibility and melt fluidity; it can be blended with PAI (Polyamide-imide) to formulate primer coats, enhancing the resistance to steam sterilization and boiling water of non-stick coatings.
3. Excellent chemical resistance. Coatings produced with this resin exhibit high resistance to saltwater, salt spray, acids, alkalis, and organic solvents.
4. Excellent compatibility and water dilutability. This resin is compatible with the vast majority of aqueous emulsions and resins and can be directly diluted with deionized water. It is suitable for direct use in formulating single-coat, water-based high-temperature coatings.
5. Complies with food safety and hygiene standards such as those of the U.S. FDA and Europe.
6. Ready-to-use dispersion, no need additional production process.

APPLICATION
Water-based high temperature resistant non-stick coatings is a flagship application for PES dispersion, driven by the global shift away from solvent-based coatings. The PES dispersion is formulate with other additives(like non-stick agents such as PTFE, fillers, and levelling agents) to create a ready-to-spray or dip coating.
PES dispersion is then applied to substrate and baked at high temperatures to evaporate the water and fuse the PES particles into a continuous, durable film. PES has a high glass transition temperature, allowing the coating to withstand continuous exposure to high heat without degrading, cracking, or loosing its non-stick properties.
As a water-based system, it contains no harmful solvents, making it safer for workers, consumers, and the environment. The cured coating is compliant with food contact regulations. Bonds strongly to metals like aluminum and stainless steel. Typical applications are non-stick cookware like bakeware, roasting pans, griddles, and muffin trays.
PES dispersion are used as a base for creating high-performance, water-based adhesives and primers. The dispersion can be used directly as a high-temperature adhesive or as a additive/binder in adhesive formulations. PES is applied to a surface, the water evaporates(often with mild heating), and then the bond is fully cured under heat and pressure.
