Product Description of Triethylene Glycol Dimethacrylate CAS#109-16-0
Triethylene Glycol Dimethacrylate, also known as TEGDMA, is a difunctional methacrylate monomer. It appears as colorless to pale-yellow oily liquid with a mild ester-like smell. Its molecular weight is 286.32, and it contains two reactive carbon-carbon double bonds for free-radical polymerization.
This low-viscosity substance dissolves well in most organic solvents and shows limited solubility in water. It is commonly stabilized with polymerization inhibitor for long-term storage. As a reliable cross-linking raw-material, it improves the surface hardness and wear-resistance of cured polymers and fits well for UV-cured supplies and dental composite resins.

Product Application of Triethylene Glycol Dimethacrylate CAS#109-16-0
Triethylene glycol dimethacrylate acts as a vital dual-functional cross-linking monomer within polymer-related industries. It is frequently added into ultraviolet-curable coatings, printing inks and adhesive formulations to raise cross-link density, enhancing finished goods’ surface hardness and abrasion-resistant capacity.
Besides surface-treatment materials, the monomer serves as essential filler matrix raw-material for dental composite restoratives. It can also be adopted for producing optical materials, polymer hydrogels and resin-based grinding accessories. In addition, it works as a chemical modifier to optimize the shrinkage-proof performance of different kinds of synthetic resin systems.
