  • Applications

    Dimethylol glycol is a difunctional hydroxymethyl diol used primarily as a reactive crosslinking agent and polymer building block in coatings, adhesives, and plastics. In industry, it promotes cure and network formation in waterborne and solventborne systems by reacting with isocyanates, aldehydes, or melamine/phenolic resins to improve hardness, adhesion, and chemical resistance. It also serves as an intermediate for synthesizing specialty polyols and polyurethane formulations, enabling the production of durable adhesives and sealants with enhanced performance. Additional applications include epoxy and acrylic resin systems for electronics encapsulation and protective coatings, and as a chemical intermediate in thermoset materials for coatings and inks. Formulations should consider processing conditions and local regulations.
