Trimethylolpropane triacrylate is a typical trifunctional monomer with higher viscosity than monofunctional and bifunctional monomers. However, compared to multifunctional monomers, it has lower viscosity and good solubility. This monomer can provide high curing speed and high crosslinking density, forming a curing film with excellent solvent resistance, hard scratch resistance, and brittleness. Its price is relatively low, and although it has some irritation to the skin, it is still the most commonly used multifunctional monomer.
