introduction

· 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.

· Trimethylolpropane is used in saturated polyesters for coil coatings, alkyds for paints, polyurethanes for coatings and elastomers, acrylic acid esters for radiation curing, esters for synthetic lubricants, rosin esters and for surface treatment of pigments.

· Another important field of application is in medium-oil and short-oil alkyd resins (→ Alkyd Resins).
