As carboxylic acid-type hydrophilic chain extenders, DMPA and DMBA have found widespread application in the production of water-based polyurethanes, thanks to their unique molecular structures and superior performance characteristics. Our company maintains a robust cooperative relationship with our manufacturing partners, ensuring a stable and consistent supply of these products over the long term. Furthermore, we offer a comprehensive range of complementary products for the water-based polyurethane resin, coating, and related industries—including DMPA-modified polyester polyols, water-based wetting and leveling agents, water-based antioxidants, water-based light stabilizers, as well as eco-friendly catalysts (such as organic bismuth compounds) and tin catalysts (e.g., T-12).

Water-based polyurethane is an environmentally friendly polymeric material widely utilized in eco-conscious coatings, leather products, adhesives, inks, and various surface finishes. Driven by the ever-increasing market demand for eco-friendly materials—and compounded by current and anticipated future challenges facing solvent-based polyurethanes (such as supply shortages of key solvents like DMF and persistently high production costs)—the water-based polyurethane industry is poised for significant growth opportunities. Consequently, as essential synthetic auxiliaries for water-based polyurethanes, DMPA and DMBA are also expected to experience accelerated market growth, promising a bright outlook for their future development.
