Water Based Polyurethane Resin For Package Printing Coating

Water-borne polyurethane dispersions (PUDs) are film-forming binders that deliver solvent-like performance with near-zero VOC. In package-printing applications they are used as clear or pigmented over-print varnishes (OPVs), protective lacquers, or tie-coats for flexible, paper-based and rigid containers.



Product Description

RHERI™U112 is a water-based aliphatic polyurethane dispersion ,widely used for Gravure and CI Flexo Printing, Lamination, and Surface applications. Designed with a focus on eco-friendliness, aqueous polyurethane resin is fully water-reducible and Toluene and Ketone-free, making it ideal for sustainable and high-performance packaging solutions. This mono water-soluble polyurethane emulsion formulation for inks ensures excellent transfer properties and high-speed compatibility, delivering exceptional results for flexible packaging
