CASAMID® 831

CASAMID® 831 by Thomas Swan is a thermoplastic, non-reactive co-solvent polyamide resin. It offers good lay, while exhibiting limited gelation resistance and low tolerance to polar solvents.

• It delivers the highest performance in alcohol-hydrocarbon systems and also stabilizes pigment dispersion.
• It is used in flexible packaging applications such as gravure inks on OPP, PE, and PET films, providing fast drying, high adhesion, and strong color holdout.
• It offers excellent flow, anti-blocking resistance, exceptional ink transfer, strong film integrity, wetting, and solvent release for inks such as flexographic inks.
• CASAMID® 831 is used in publication and graphics applications, including inks for catalogues, labels, and decorative film prints, ensuring smooth laydown and sharp definition.
• It is also used in industrial coatings, including polyamide-modified nitrocellulose lacquers or phenolic blends, to enhance hardness and flexibility.
• It is used in overprint varnishes as topcoats for printed films, providing mechanical protection along with high gloss, and clarity in clear lacquer systems.
• It is compliant with FDA 175.320 guidelines.
• It has a shelf life of 12 months.
