Key Features
◊ Outstanding Anti‑scratch and Soft‑touch Performance
This Polyurethane Dispersion forms a tough yet supple film that delivers exceptional resistance to surface abrasion and marring, while imparting a pleasant soft‑feel effect to coated films and paper. The unique self‑matting mechanism eliminates the need for external matting agents, providing a uniform matte finish without compromising tactile quality. Compared to conventional matted coatings, this Polyurethane Dispersion maintains its aesthetic and haptic properties even after prolonged handling or friction.
◊ Excellent Adhesion and Anti‑blocking Properties
Specifically engineered for a wide range of substrates including PVC, BOPP, plastics, films, and paper, this Polyurethane Dispersion exhibits strong anchoring to both polar and non‑polar surfaces. It simultaneously provides outstanding anti‑blocking performance, preventing adjacent coated layers from sticking together during storage or converting. Such balanced adhesion and anti‑blocking behavior make this Polyurethane Dispersion an ideal choice for high‑speed roll‑to‑roll coating processes where film handling reliability is critical.
◊ Solvent‑free Self‑matting Formulation with Superior Processability
As a true solvent‑free and waterborne Aqueous Polyurethane Dispersion, it offers a low‑VOC, environmentally friendly alternative to solvent‑based matting systems. The dispersion exhibits a Brookfield viscosity of 200–2000 mPa·s (at 25°C), ensuring excellent flow and leveling on conventional coating lines including gravure, flexo, and bar coating. It can be optionally combined with a crosslinker to further enhance abrasion resistance and chemical durability, while still preserving the intrinsic soft‑touch characteristic and matte appearance.
◊ Sustainable and Storage‑stable Design
This Waterborne Polyurethane Dispersion is formulated without added solvents or external matting agents, supporting the recyclability of coated film and paper substrates. It is stable for six months when stored at 20°C in original unopened containers, and recommended storage temperature ranges from 5°C to 35°C. Proper handling avoids freeze‑thaw or high‑temperature induced sedimentation, ensuring consistent performance in industrial production. By delivering high‑performance matting, anti‑scratch, and tactile properties in a waterborne system, this Polyurethane Dispersion meets the packaging and printing industry’s growing demand for sustainable yet functional coatings.

Applications
◊ Soft‑Touch Overprint Varnishes for Flexible Packaging
This Polyurethane Dispersion is ideally suited as a self‑matting, soft‑feel topcoat for food, cosmetic, and consumer goods packaging films such as PVC and BOPP. It delivers outstanding anti‑scratch performance and a pleasant tactile sensation, while providing excellent anti‑blocking properties that facilitate high‑speed converting and stacking operations.
◊ Water‑Based Matte Coatings for Film and Paper Substrates
Serving as a primary self‑matting binder, this Polyurethane Dispersion enables the formulation of low‑gloss, uniform matte finishes on plastic films (PVC, BOPP, PET) and paper. Its solvent‑free nature and strong adhesion ensure consistent coating quality without delamination, even on challenging non‑porous surfaces.
◊ Anti‑Scratch Protective Layers for Printed Graphic Films
When applied as a protective overcoat on digitally printed or gravure‑printed films, this Polyurethane Dispersion forms a tough yet flexible barrier that resists surface marring, scuffing, and handling damage. The self‑matting effect preserves the printed design’s visual integrity while adding a premium soft‑touch feel, ideal for promotional posters, decorative laminates, and retail signage.
◊ Anti‑Blocking Topcoats for Roll‑to‑Roll Coating Processes
This Polyurethane Dispersion exhibits excellent anti‑blocking behavior, preventing adjacent coated layers from sticking together during storage or rewinding. Combined with its outstanding adhesion to various films, it ensures reliable processing in high‑speed gravure and flexo coating lines, reducing waste and downtime.
◊ Sustainable Matte Coatings for Paper Packaging
As a solvent‑free, low‑VOC Polyurethane Dispersion, it meets the growing demand for environmentally friendly coatings in paper‑based packaging, such as gift wraps, cartons, and paper bags. The dispersion provides a uniform matte appearance, soft touch, and good abrasion resistance, fully compatible with conventional coating equipment.
◊ Crosslinkable Haptic Coatings for Demanding Applications
Optionally combined with a crosslinker, this Polyurethane Dispersion can achieve enhanced mechanical durability and chemical resistance while retaining its self‑matting and soft‑touch characteristics. Such formulations are particularly suitable for high‑wear applications like luggage tags, menu covers, and industrial film protection, where both aesthetics and longevity are required.
Benefits
Achieve Outstanding Anti‑scratch Performance and Premium Soft‑touch Feel with Self‑matting Effect
This Polyurethane Dispersion forms a uniform matte film upon drying without requiring external matting agents. The unique self‑matting mechanism, combined with excellent film toughness, delivers exceptional resistance to surface marring and abrasion, while imparting a luxurious soft‑touch sensation to coated films and paper. Compared to conventional matted coatings, this Polyurethane Dispersion retains its aesthetic and haptic properties even after repeated handling or friction, making it ideal for high‑touch packaging and printed graphics.
