Trimethylolpropane triacrylate (Cat No.:M082480) is a trifunctional acrylate ester widely used as a reactive diluent and crosslinking agent in UV-curable coatings, inks, adhesives, and resins. Its three acrylate groups enable rapid polymerization under UV or electron beam exposure, forming tough, chemically resistant networks. TMPTA enhances hardness, adhesion, and weatherability in cured films while reducing viscosity in formulations. It is compatible with a variety of monomers and oligomers and is valued in applications requiring fast cure speed, high-performance finishes, and durable surface properties in industrial and graphic arts sectors.
