Pentaerythritol triacrylate is a commonly used functional monomer. It is a colorless to slightly yellow liquid with low viscosity and good solvent-free properties. It has good heat resistance, chemical resistance, and light resistance. It is relatively stable at room temperature and can effectively copolymerize with other monomers. Mainly used as a crosslinking agent and diluent in room temperature curing (photopolymerization or free radical initiation) coatings and inks. It can be used for the preparation of UV cured coatings, acrylic resins, inks, photosensitive resins, etc. It can also be used as an important raw material in fields such as electronic and optoelectronic devices, optical materials, adhesives, and adhesives.
