Trimethylolpropane Triacrylate (abbreviation: TMPTA) is a typical trifunctional monomer, its viscosity is higher than that of monofunctional and bifunctional monomers, but compared with multifunctional monomers, its Chemicalbook viscosity is relatively low, Has good dissolving power. This monomer provides high cure speed and high crosslink density, and can form a hard, scratch-resistant and brittle cured film with excellent solvent resistance. Its price is relatively low, although it is irritating to the skin, it is still the most commonly used multifunctional monomer.
