Trimethylolpropane Triacrylate (TMPTA)
This product is a trifunctional monomer with high boiling point, high activity, low volatility and low viscosity. It has good compatibility with acrylic prepolymers, can be used as reactive diluent, used for UV and EBChemicalbook radiation crosslinking, and can also become a composition of crosslinking polymerization, and is also widely used in light-curable inks, surface coatings, In coatings and adhesives, it imparts good wear resistance, hardness, adhesion and brightness.
