Trimethylolpropane ethoxylate triacrylate (Cat No.:I044400) is a trifunctional acrylate monomer widely used in UV-curable and electron beam (EB) curable formulations. It features three acrylate groups and an ethoxylated trimethylolpropane backbone, offering excellent crosslinking density, flexibility, and chemical resistance. TMPEOTA enhances the performance of coatings, inks, adhesives, and 3D printing resins by improving hardness, adhesion, and durability. Its low viscosity and good compatibility with other resins make it a versatile component in high-performance polymer systems, especially where fast curing, high strength, and low shrinkage are essential.
