Tropropylene Glycol Diacrylate (TPGDA) is a colorless or slightly yellow liquid with low viscosity and low vapor pressure. It has good optical performance, high refractive index, and low refractive index dispersion. It is soluble in organic solvents such as esters, alcohols, and aromatic hydrocarbons, but insoluble in water. Tripropylene glycol diacrylate is widely used in the field of UV curing, such as UV curable coatings, inks, adhesives, coatings, and resins. It can be quickly cured by ultraviolet or electron beam radiation, producing high-quality films with good adhesion and durability. It can also be used in fields such as optical coating, optical fibers, 3D printing, medical and dental materials in electronic products.
