Dipropanediol diacrylate is a common acrylic acid derivative monomer, used as a crosslinking agent in light curing or radiation curing, can reduce the radiation dose; When used as active diluent, the viscosity of resin system can be reduced obviously.It can be used as crosslinking agent instead of methylodiene amide in acrylate emulsion system products, and has the characteristics of good crosslinking effect, less dosage and convenient use. Low-odor colorless or yellowish clear liquid,Insoluble in water, soluble in aromatic solvents, most acrylic acid esterified prepolymers have good solubility.
