Polyester-based and polyether-based polyurethane (PU) resin are two commonly used types of waterborne PU resins. Here are the advantages and disadvantages of each type: Polyester-based waterborne PU resin: Advantages: Excellent mechanical properties: Polyester-based polyurethane resin offer good tensile strength, elongation, and impact resistance, making them suitable for applications that require...
Polyurethane binder is a type of polymer that plays a crucial role in gravure printing inks. Gravure printing, also known as rotogravure or simply gravure, is a high-speed printing process that uses engraved cylinders to transfer ink onto a substrate, such as paper, film, or foil. In this process, the polyurethane binder serves several important functions: 1: Adhesion: The primary function of...
Water-based PU resin is a polyurethane system that uses water instead of organic solvents as the dispersion medium. It is a new type of environmentally friendly polymer material.Because of its excellent environmental protection, excellent mechanical properties, and good compatibility with other water-based resins,water-based PU resin is widely used in adhesives, coatings, and coating products.What...
Polyurethane resin enhances adhesion in plastic inks through its unique chemical structure and physical properties.This process involves multiple aspects, from molecular-level interactions to improvements in macroscopic physical properties.
