Polyamide-Imide (PAI) Resins
Polyamide-imide (PAI) resins are thermoset ultra-polymers that are robust, chemical resistant and thermally stable. The polymers will typically withstand extended service temperatures higher than 250°C. Coatings produced from these polymers have been used in non-stick cookware, dry film lubricants, wire insulation, printed circuit boards, internal can coatings, composites and aerospace applications.
