Storage:

The dispersion should be stored in a frost-free place in tightly sealed containers. It contains no preservative.

Application:

Some coatings are just built different—and PUD-913 proves it. With a solid content of 33±1%, this aliphatic polyurethane dispersion brings serious strength to the table without losing its cool. If you’re chasing a finish that’s rock-hard yet still resilient, this one’s for you.

Let’s break down the numbers. Elongation sits between 150–200%, meaning it’s not super stretchy—but that’s by design. Instead, PUD-913 leans into hardness, durability, and its solid tensile strength of 10.2 MPa, backed by a modulus of 8.0 MPa. Translation? This coating holds its ground—no flex zone.

What makes PUD-913 a standout? It’s packed with weather resistance, wear resistance, heat resistance, hydrolysis resistance, chemical resistance, and yes—stain resistance. Basically, if it exists to ruin a finish, PUD-913’s already one step ahead.

It’s a killer pick for surfaces that need to stay sleek, clean, and strong—no matter the environment. From consumer goods to demanding industrial uses, this dispersion gets the job done and then some. While it does contain NMP, its performance is what earns it a seat at the high-performance table.

Choose PUD-913 when you need a finish that holds up under pressure, stays tough under heat, and won’t crack under chaos.
