CASAMID® 843W

CASAMID® 843W by Thomas Swan is an alcohol-reducible thermoplastic polyamide resin modified with wax. It combines the features of both alcohol-soluble and alcohol-reducible polyamides.

• It provides broad solvent compatibility.
• It has low static and dynamic coefficients of friction.
• Its excellent gelation resistance offers high-speed printing and improved ink transfer.
• CASAMID® 843W has very low odor, suitable for indirect food contact and hygiene-sensitive sectors.
• It has a thermoplastic nature that aids in fast drying and re-solubility during multi-pass printing.
• It improves print clarity and scuff resistance in flexographic and gravure surface inks, especially on polyethylene and BOPP.
• It enhances slip, anti-blocking, and rub resistance in overprint varnishes and lacquers used for flexible packaging.
• It ensures odor neutrality and a smooth finish in personal care packaging for sensitive applications.
• It provides reliable release properties in cold-seal and release lacquers without additional modifiers.
• It is optimal for achieving smooth coating flow and excellent film formation in specialty coatings for films.
• For enhanced surface properties, it can be blended with 5–10% standard polyamides or nitrocellulose systems.
• It is recommended to use 15–30% resin solids in the total formulation for inks and overprint varnishes.
• It has a shelf life of 12 months.
