When flexibility, water resistance, and long-term stability are non-negotiable, SiwoPUD-2307 steps up. This aqueous, aliphatic polyurethane dispersion based on polyester is engineered for performance where it matters most—delivering high elasticity, superior mechanical strength, and seamless compatibility with a wide range of resin systems.
Formulated with a 35% non-volatile content, SiwoPUD-2307 is supplied in water and is completely free from organic solvents or preservatives, making it a smart, cost-effective solution for formulators seeking eco-conscious alternatives. Its translucent appearance, non-ionic ionicity, and pH value between 6.0 and 7.5 make it versatile and stable across a broad application spectrum. Add to that a viscosity of ≤200 mPa·s and a mean particle size of ≤100 nm, and you get a product that processes cleanly and blends efficiently into various formulations.
Performance-wise, SiwoPUD-2307 doesn’t disappoint. Its film offers excellent elongation at 700–800%, ensuring it can stretch and return without failure. With a tensile strength of 20.1 MPa and 100% modulus of 2.5 MPa, it balances flexibility with structural integrity—ideal for coatings that must endure stress while maintaining form. Its glass transition temperature (Tg) of -25°C allows the film to remain pliable even in colder conditions, while its non-yellowing nature ensures a clean, lasting finish over time.
The formulation is also known for its good shear stability, making it dependable under mechanical stress during production or application. Even better, it shows excellent water resistance, extending the lifespan and durability of the finished product.
Compatible with anionic and cationic waterborne polyurethanes and other cationic and anionic waterborne resins, SiwoPUD-2307 plays well with others, offering formulating flexibility without compromising performance.
If you’re looking for a robust, eco-smart polyurethane dispersion that can stretch, resist, and perform across environments, SiwoPUD-2307 is your next go-to solution.
