2,2-Bis(hydroxymethyl)butyric Acid (DMBA) is an important multifunctional monomer and intermediate used in the manufacture of water‑soluble polyurethane and polyester systems. Its hydroxymethyl and carboxylic acid functional groups enable cross‑linking, modification and improved hydrophilicity in coatings, adhesives, leather coatings and specialty polymer materials. It finds particular value in producing eco‑friendly resin systems, offering an alternative to traditional monomers with enhanced water dispersibility and functionality.
