In the printing industry, the quality of ink directly affects the appearance and performance of printed products. And ink binder, as an indispensable part of the ink, its performance and quality have a crucial impact on the overall performance of the ink. As one of the leading industrial laminating adhesive manufacturers in the domestic high-performance composite polyurethane adhesive industry, we are fully aware of the importance of ink binder and are committed to providing high-quality ink binder products to our customers.
This type of PU resin for ink primarily functions to firmly adhere pigments, dyes, and other solid particles to the substrate, forming a uniform printing layer. It not only needs to have good adhesion performance but also good compatibility with pigments, dyes, and other solid particles to ensure that the prints are vivid and vibrant.
Excellent Yellowing Resistance
Ink binder use advanced polyurethane resin technology, which provides excellent yellowing resistance. Even under long-term use and exposure to light, printed products can maintain vivid colors and resist fading.
Excellent Adhesion to Film Substrates
Ink binder contain various polar groups in the molecular chain segments, which can form hydrogen bonds with multiple polar substrates such as PET and PA, achieving firm adhesion. This ensures that printed products can maintain stable printing effects even under complex environmental conditions.
Good Affinity and Wetting with Pigments
Ink binder use special preparation processes and introduce polar groups such as urethanes, granting them excellent dispersing and wetting properties with pigments. This helps to achieve uniform distribution of pigments in the ink, improving the color uniformity and saturation of printed products.
Good Resin Compatibility
These laminating adhesives are highly compatible with various resins like aldehyde-ketone resin and chlorinated vinyl chloride resin. This provides users with more formula options and allows them to adjust the ink's performance according to actual needs, meeting the requirements of different printing processes.
Excellent Film-Forming Properties
Ink binder, based on traditional polyurethane resin, incorporate urethane groups, significantly enhancing the cohesive strength and film-forming ability of the resin. This allows printed products to form a strong and durable film layer after drying, improving abrasion resistance and weather resistance of the prints.
Good Solvent Release
Ink binder have good solvent release properties, enabling rapid solvent release during the printing process for quick ink drying. This helps improve printing efficiency and reduce energy consumption.
Ink binder, with their excellent performance and wide application fields, have become the preferred brand in the printing industry. In future development, we will continue to focus on technological innovation and product upgrades to provide customers with een higher qualityink adhesive products and solutions.
