PAI powder
PAI is a family of soluble polyamide-imides sold in powder 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.
AI 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.
AI-10 powder has an impressive record of proven performance in high-temperature coatings and adhesives. These include electrical wire coatings, corrosion-resistant coatings, non-stick cookware coatings, and industrial low-friction coatings.
AI-10 is soluble in dipolar aprotic solvents such as N-methyl pyrrolidone (NMP), dimethylacetamide (DMAC), dimethylformamide (DMF) and dimethylsulfoxide (DMSO) to at least 35% solids. Mixtures of these solvents with other diluents are possible. Cast solutions are thermally cured up to 250-300°C (480-570°F) to achieve maximum performance properties. Please see Torlon AI-10 Coatings for more information.

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.
