What is Polyurethane Dispersion (PUD)? - SNP

Water-based aliphatic polyurethane dispersions (PUDs) are eco-friendly, zero-VOC binders used in high-performance printing inks, particularly for flexible packaging, textiles, and gravure printing. They provide superior durability, high flexibility, excellent adhesion to diverse substrates (PET, OPP, PVC), and anti-yellowing properties, making them ideal for high-speed, high-quality printing.

Performance: Waterborne polyurethane dispersions (WPU) offer high tensile strength (
), high elongation (
), and superior abrasion resistance.
Environmental & Safety: SNP Inc. offers Co-solvent free and NMP-free products to address the VOC requirements of modern users, and they are generally non-yellowing and safe for varied applications.
Printing Applications: Used in water-based aliphatic polyurethane dispersions for printing ink and water pigment-based dispersions for gravure ink, as well as textile screen printing.
Technical Specifications: Typical anionic aliphatic PUDs show a solid content of
, a pH of 7.0-8.0, and a viscosity of 200-300cP.

For specific applications in packaging and textile coatings, SNP Inc. provides NMP-free, non-yellowing, high-solids-content aliphatic polyurethane dispersions designed for durability and high-speed, high-quality printing. Additionally, Water Based Aliphatic Polyurethane Dispersions for Printing Ink from Runxinlianchem provide a durable and non-yellowing solution for high-performance ink formulations.
