Application:

If you’re after a polyurethane dispersion that brings clarity, consistency, and durability all in one sleek formula, PUD-1209 is the one. This aliphatic, NMP-free polyurethane dispersion is tailor-made for modern ink systems, water-based varnishes, and coated paper applications that require a smooth, clean finish with lasting performance.

With a solid content of 33±1%, PUD-1209 lays down an even, clear film that enhances the look and feel of the final product without interfering with color vibrancy or surface detail. Its medium hardness makes it tough enough for everyday handling while keeping the finish sleek—not stiff.

On the performance side, it holds up impressively well. The film stretches with 500–600% elongation, boasts a tensile strength of 11.2 MPa, and carries a 100% modulus of 2.5 MPa, meaning it’s flexible enough to adapt to coated materials and strong enough to resist tearing or cracking.

Add in its excellent water resistance and abrasion performance, and you’ve got a reliable resin that can handle the demands of high-speed printing, packaging, labeling, or decorative paper finishes. It keeps everything looking sharp—even when things get handled, rubbed, or splashed.

So, whether you’re formulating for print clarity, product protection, or just need a finish that lasts, PUD-1209 is your versatile, high-performing base.
