SiwoPUD®-2411

When clarity, strength, and performance are non-negotiable, SiwoPUD-2411 delivers. Developed by Shanghai Sisheng Polymer Materials Co., Ltd., this aqueous, aliphatic polyurethane dispersion based on polycarbonate technology offers a superior combination of durability, flexibility, and visual quality—making it an exceptional base for advanced printing ink applications.

What sets SiwoPUD-2411 apart is its finely tuned physical makeup. Supplied as a 32% non-volatile solid in water, this dispersion maintains a translucent appearance and has a pH range of 7.0–9.5, ensuring compatibility across a broad range of ink formulations. Its mean particle size of ≤100 nm allows for smooth application and fine surface detail, crucial for print clarity and consistency.

Performance-wise, it impresses with a tensile strength of 46.8 MPa and an elongation range between 550–650%, ensuring both stretchability and structural integrity. The 100% modulus at 9.6 MPa gives it the right amount of firmness without compromising flexibility. Whether printed onto paper, films, or specialty surfaces, SiwoPUD-2411 maintains its grip and integrity under stress.

Its good shear stability and fast drying capabilities make it ideal for high-speed production environments, while its non-yellowing nature ensures long-term aesthetic quality. Plus, SiwoPUD-2411 is NMP-, NEP-, and DMAC-free, aligning with today’s environmental and safety standards—a key advantage for manufacturers looking to lower VOC content and comply with global regulations.

Additionally, this dispersion boasts high acid value, excellent ductility, strong elasticity, and outstanding water resistance. That makes it perfect for inks that must endure both handling and exposure without cracking, fading, or bleeding.

Engineered for excellence and sustainability, SiwoPUD-2411 is your go-to solution when you need a high-performance polyurethane dispersion designed for modern printing demands—without the compromise.
