Songwon's New Ink Binder to Improve Print Quality on Packaging Film

Songwon Industrial Co Ltd has introduced HI-THANE A-890K, an aliphatic, solvent based polyurethane ink binder for use in the manufacture of gravure printing inks for a variety of laminates.

This new binder is distinguished by its exceptionally high lamination bonding strength on various plastic films, especially PET, nylon and OPP. Its outstanding heat resistance makes it suitable for use in both retortable and non-retortable flexible packaging laminates. With its very high re-solubility, HI-THANE A-890K counteracts scale formation in gravure printing cells, improving print quality and reducing machine maintenance. With its low viscosity, this versatile binder helps to boost the colour strength of inks, promoting top quality printing results.

HI-THANE A-890K is suitable for use in pigment grinding to help achieve the required rheological properties and the smaller particle sizes that increase the colour strength of prints. It can be used on its own or together with other binders, such as vinyl chloride-vinyl acetate and polyvinyl butyral copolymers.
