When you need a coating that works as hard as your surfaces do, SiwoPUD-F130 delivers. This aromatic, aqueous polyurethane dispersion based on polyester is engineered for strength, stability, and longevity—making it a perfect fit for wood coatings and demanding industrial applications that require high durability and excellent finish retention.
Supplied as a 35% dispersion in water, SiwoPUD-F130 forms a film that’s hard, heat-resistant, and exceptionally wear-resistant—qualities that make it an asset for high-traffic surfaces, protective topcoats, and rugged industrial environments. Once applied, its film achieves a Shore A hardness of 90, ensuring a resilient, non-flexible surface that stands up to abrasion and mechanical stress.
One of the key benefits? It dries fast. This fast-drying dispersion improves throughput and production efficiency, all while maintaining visual integrity thanks to its translucent appearance. Even in high-heat environments or under frequent use, SiwoPUD-F130 holds its own, resisting softening and breakdown over time.
Formulated with sustainability in mind, this product is completely NMP, NEP, and DMAC free, aligning with current environmental regulations and supporting safer workplace practices. It also offers good shear stability and a mean particle size of ≤100 nm, resulting in smooth, uniform film formation without clogging or uneven texture.
Unlike many other dispersions in its category, SiwoPUD-F130 doesn’t rely on added preservatives, and yet it maintains excellent storage reliability—just keep it in a frost-free environment, tightly sealed, and you’re good to go.
Despite its pH range of 7.0–9.5 and viscosity ≤300 mPa·s, the application process remains user-friendly and efficient. And while it does exhibit some yellowing, this is a common and manageable trait among aromatic systems—especially when offset by the formulation’s other performance advantages.
From durable wood coatings to industrial-grade finishes, SiwoPUD-F130 is built to withstand the pressure—literally and figuratively. If your coating demands high hardness, rapid drying, and real-world resilience, this dispersion is ready to deliver.
SiwoPUD-F130 is designed for high-performance wood coatings and industrial coatings where durability, heat resistance, and surface hardness are critical.
It offers a Shore A hardness of 90, excellent wear and heat resistance, fast drying, and is free of NMP, NEP, and DMAC, making it a safer, more sustainable choice.
No—SiwoPUD-F130 forms a rigid, hard film, so it’s best suited for applications requiring structural durability rather than flexibility.
Yes. It contains no harmful solvents and supports low-VOC formulations, aligning with modern environmental standards.
As an aromatic polyurethane, it may exhibit some yellowing, especially under UV exposure. This is typical and should be considered in aesthetic applications.
Keep it tightly sealed in a frost-free environment. It contains no preservative, so proper storage is essential for product integrity.
