SiwoPUD®-E720

If you’re searching for a high-performance waterborne polyurethane dispersion that delivers strength, flexibility, and environmental safety, SiwoPUD-E720 is built for the job. This aqueous, aliphatic polyurethane dispersion based on polycarbonate chemistry combines technical resilience with exceptional application versatility, making it a go-to solution for coatings that need to withstand the elements without compromising clarity or performance.

What sets SiwoPUD-E720 apart? It begins with its medium-hardness film, engineered to be non-yellowing for long-term clarity and visual appeal—especially critical for exposed or light-colored surfaces. With a non-volatile content of 32±1%, this dispersion forms strong, consistent films with minimal buildup. Its translucent appearance, paired with a mean particle size of ≤100 nm, ensures smooth, even coatings every time.

When performance matters, SiwoPUD-E720 delivers. With a tensile strength of 47.3 MPa, this dispersion offers serious durability, while maintaining impressive elasticity with an elongation range of 500–600%. Whether you’re coating flexible surfaces or need impact resistance, the 100% modulus of 7.3 MPa provides balanced mechanical support without brittleness. Add in its dry-fast properties and good shear stability, and you’ve got a product that boosts throughput while staying reliable under pressure.

SIWO’s commitment to safety and sustainability is evident here, too. SiwoPUD-E720 is NMP, NEP, and DMAC free, making it a smart, safer choice for manufacturers focused on regulatory compliance and environmental impact. Its pH value of 7.0–9.5 ensures compatibility across a range of substrates, and its viscosity of ≤1000 mPa·s makes application effortless across various systems.

Engineered to resist water, alcohol, and wear, SiwoPUD-E720 is ideal for coating solutions that demand excellent water resistance, strong alcohol resistance, and outstanding weather durability—all without sacrificing drying time or finish quality.
