If you’re formulating a coating that needs to endure the elements, resist abrasion, and deliver a durable finish in high-performance systems, OH-PUD-1938 is your ultimate workhorse. Designed with both aliphatic/polycarbonate backbones, this waterborne polyurethane dispersion combines structural integrity with outstanding weatherability—perfect for modern 2-pack and heat-cure coating systems.
With a solid content of 35±1%, OH-PUD-1938 boasts high hydroxyl content that enhances crosslinking potential, ensuring greater hardness and extended coating life. Unlike many PUDs, it’s NMP-free, making it a cleaner choice for environmentally conscious formulations.
This dispersion is engineered to deliver high hardness, along with excellent abrasion resistance, weather resistance, and hydrolysis resistance. Whether you’re formulating protective topcoats, robust primers, or functional finishes for challenging environments, OH-PUD-1938 brings the resilience you need without compromising film quality.
It’s highly versatile—use it alone, or combine with water-based hydroxy polyacrylic resins, water-based polyesters, or even amino resins to create water-dilutable stoving coatings and primers. In 2-pack systems, pair it with a water-dispersible polyisocyanate crosslinker for strong, chemical-resistant films that cure at approximately 120–130°C.
If your coatings need to stand up to wear, weather, and time, OH-PUD-1938 is a high-performance foundation you can build on.
