SiwoPUD®-FB-10

When your formulation demands the resilience of two-component polyurethane systems—but your process calls for simplicity—SiwoPUD-FB-10 steps in with an elegant solution. This hydrophilic blocked aliphatic polyisocyanate, supplied at a robust 85% non-volatile content, is designed to deliver powerful crosslinking performance in water-diluent, one-component polyurethane stoving coatings.

What makes it so effective? It starts with the formulation. SiwoPUD-FB-10 is non-ionic, ensuring compatibility with a wide range of polyurethane dispersions. Its blocked NCO content of 11.0±1% provides strong reactivity once the coating reaches its deblocking temperature of 140℃. That heat activation unlocks the performance, forming a tight, resilient film without the complexity of traditional 2K systems.

This crosslinker is all about delivering balance—formulators benefit from the viscosity range of 5000–15000 mPa·s, which allows for easier processing and consistent film build. Its colorless to light yellowish transparent appearance ensures it won’t interfere with color clarity or finish aesthetics.

Once baked, the resultant film performs on par with conventional dual-component systems—offering high flexibility, hardness, and excellent resistance to water and solvents. That makes SiwoPUD-FB-10 a go-to for high-temperature baking applications, whether you’re working in industrial coatings, specialty adhesives, or next-gen water-based systems where durability, chemical resistance, and finish integrity matter most.

Proper storage is key to maintaining performance: keep the product in tightly sealed containers, protected from frost and direct sunlight.

For manufacturers looking to simplify their process without compromising on performance, SiwoPUD-FB-10 offers a future-forward path to durable, high-quality, waterborne coatings.
