PAI is a family of soluble polyamide-imides sold in pellets form. The polymer is tough, chemically resistant, and thermally stable. It has thermal capability similar to many polyimides, at a lower price. Coatings based on AI polymers have been shown to be cost-effective in electrical/electronic, high-temperature decorative, and corrosion prevention applications.
PAI is available in water-soluble versions that possess exceptional mechanical, thermal, chemical resistance as well as wear-resistant properties.
Torlon resins are inherently non-flammable, have outstanding electrical properties, and possess enormous temperature stability from cryogenic to 300°C and some grades are FDA compliant.

PAI-based coatings can be effectively applied by spray, roll, spin, or curtain techniques. Usually dry film thicknesses from 10-20 µm are readily achieved in a single coating pass. Greater film thicknesses can be achieved by applying multiple coats.
Regardless of the method employed, it is essential to assure appropriate preparation of the substrate prior to application of coating. Once complete, application equipment should be purged of coating and cleaned with a true solvent.
