Fluorine-free Cookware Coatings Solution Environmental-friendly Water-based PAI Dispersion

PAI (Polyamide-Imide) dispersion refers to a form of this high-performance polymer where PAI resin particles are suspended in a liquid medium (typically water or a solvent blend). This form enables applications and processing methods that are not possible with solid PAI (e.g., powders or pellets).

Durle® SI-601 Environmentally Friendly Water-based Polyamide-imide (PAI) Dispersion is an environmentally compliant high-performance resin material developed by Quark. It is engineered to eliminate EU REACH-regulated solvents such as NMP and contains no yellowing-prone materials like organic amines. Functional coatings (including non-stick coatings) produced with this material exhibit a stable bluish hue without yellowing tendencies.

This product offers exceptional high gloss, high hardness (particularly hot hardness), superior wear resistance, and excellent corrosion resistance among water-based coatings. It represents the top-tier specialty engineering material currently available for water-based non-stick coatings, delivering unmatched comprehensive performance.

※ The solvent composition of this dispersion consists of water and N-butylpyrrolidone.  

Advantages of the Dispersion Form for These Applications:

Ease of Application

Uniform Thin Films

Water-based dispersions offer easier handling and environmental compliance

Low-Pressure Processing

In summary, PAI dispersion is primarily applied as an enabling form to leverage the polymer's ultra-high-performance properties onto surfaces and into structures where traditional melt-processing is impossible. Its core value lies in creating thermally stable, insulating, and protective coatings for the cookwares, household appliances, aerospace, and industrial manufacturing sectors.
