APPLICATION

Polyamide-imide (PAI) resin is a high-performance engineering polymer renowned for its outstanding thermal stability, mechanical strength, and chemical resistance. Its primary applications include:

Water-based High-Temperature Coatings

Used in protective coatings for metal components in aerospace, automotive, and industrial equipment, offering sustained performance at temperatures up to 250–300°C.

Water-based High-Temperature Adhesives

Serves as a critical component in heat-resistant adhesives for bonding metals, ceramics, and composites in demanding environments.

Insulation Coatings for Enameled Wires

Applied as insulation coatings for electrical wires and windings, providing excellent dielectric properties and thermal endurance in motors, transformers, and electronic devices.

Additionally, PAI resin is utilized in advanced composites, precision-molded components, and chemically resistant surfaces, making it indispensable in sectors where extreme operational conditions are prevalent.
