Description and Uses
Trimethylolpropane acts as a precursor to alkyd resins, high-gloss coatings and ion exchange resins. It is also employed as a multifunctional monomer utilized for the production of coatings, ethoxylated and propoxylated trimethylolpropane derivatives. Further, it serves as a building block in the polymer industry.
