SiwoPUD®-1512X2

When coating performance depends on stretch, strength, and surface grip, SiwoPUD-1512X2 is a clear standout. Engineered as an aqueous anionic dispersion based on polyester, this polyurethane dispersion brings together high elasticity, non-yellowing clarity, and advanced adhesion for even the most stubborn substrates.

From the moment you work with it, SiwoPUD-1512X2 shows off its versatility. Supplied as a 35% non-volatile content in water, it offers easy formulation handling without the environmental trade-offs—completely free of NMP, NEP, DMAC, or any harmful solvents. This makes it a top-tier choice for manufacturers seeking safer, eco-conscious materials without compromising performance.

Once applied, SiwoPUD-1512X2 forms a translucent film that’s as durable as it is flexible. The numbers speak volumes: with an elongation of 1400–1500%, this dispersion stretches far beyond typical coatings while maintaining structural integrity. Pair that with a tensile strength of 26.5 MPa and a 100% modulus of 1.6 MPa, and you’ve got a formula that balances gentle softness with remarkable mechanical strength.

But what really sets this dispersion apart is its adhesion. It delivers excellent bonding to surfaces that typically resist coatings—PVC, PET, OPP, BOPP, umbrella fabric, nylon, and more. In fact, when it comes to adhesion on PET, OPP, and BOPP, SiwoPUD-1512X2 outperforms even its predecessor, PUD-1512LF, making it a go-to for high-performance packaging films and specialty textiles.

Another bonus? It’s non-yellowing, ensuring long-lasting clarity and aesthetic appeal in demanding visual applications. With a pH range of 7.0–9.0, viscosity ≤200 mPa·s, and no added preservatives, it’s stable, consistent, and easy to integrate into production processes. Just be sure to store it in a frost-free environment in tightly sealed containers to maintain optimal performance.

For manufacturers working with hard-to-coat surfaces and high-stretch applications, SiwoPUD-1512X2 isn’t just another dispersion—it’s a smart, high-adhesion solution that holds tight without letting go.
