Triethylene glycol dimethacrylate tegdma
Manufactured by Merck Group
Sourced in United States
Triethylene glycol dimethacrylate (TEGDMA) is a dimethacrylate monomer used as a cross-linking agent in various industrial and laboratory applications. It is a colorless, viscous liquid with a high boiling point. TEGDMA is commonly used in the formulation of dental composites, adhesives, and sealants to improve their mechanical properties and durability.

aminoethyl methacrylate (DMAEMA) were purchased from Aladdin (Aladdin
Biochemical Technology, Shanghai, China). Triethylene glycol dimethacrylate
(TEGDMA) and camphoroquinone (CQ) were purchased from Sigma-Aldrich
(St Louis, MO, USA). Bis-GMA and TEGDMA were mixed at mass ratio =
1:1; then, 0.7% DMAEMA and 0.7% CQ were added as photoinitiators (the
resulting resin composite is denoted as the BT resin). The TCP and
TCP-G particles were mixed with BT resin to form TCP- and TCP-G-containing
resin composite, respectively, at a weight fraction of 15%. Both composites
were carefully blended until the particles were homogeneously distributed
in the BT resins. GIC (Fuji IX, GC, Japan) and a commercial resin
composite (SonicFill 2, Kerr, USA; denoted as SF) were used as the
control groups.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
