TMPTA is also called trimethylolpropane triacrylate. It is a widely used reactive diluent in ultraviolet light (UV) and electron beam (EB) curable coatings and inks. It imparts crosslinking to the cured polymer providing hardness and chemical resistance. It has excellent features of high reactivity, high crosslink density, high gloss, good hardness, and good abrasion resistance.
