Di-functional Monomer

Each molecule of the bifunctional monomer contains two active groups that can participate in the photocuring reaction, so the photocuring rate is faster than that of the monofunctional monomer, and crosslinking occurs during film formation, which is beneficial to improve the physical and mechanical properties and chemical resistance of the cured film.Due to the increase in molecular weight, the viscosity also increases accordingly but still maintains good dilution, less volatility, and lower odor. Difunctional monomers are widely used in photocurable coatings and ink products.

Difunctional monomers are mostly diol structures, mainly ethylene glycol diacrylates, propylene glycol diacrylates and other glycol diacrylates.
