Trimethylolpropane Triacrylate (TMPTA) CAS 15625-89-5 is a trifunctional acrylic monomer used extensively as a reactive diluent and crosslinker in UV/EB-curable coatings, inks, adhesives and composite resins. With three acrylate groups, TMPTA imparts high crosslink density, solvent resistance and mechanical strength to cured networks, delivering rapid cure response and outstanding hardness. It is commonly employed where abrasion resistance, dimensional stability and chemical resistance are essential, such as industrial coatings, electronics encapsulants and high-performance adhesives.
