| 保管条件 | Temp during storage must be kept low to minimize formation of peroxides and other oxidation products. ... Storage temp below 30 °C are recommended for the polyfunctional methacrylates. ... The methacrylate monomers should not be stored for longer than one year. Shorter storage times are recommended for the aminomethacrylates, ie, three months, and the polyfunctional methacrylates, ie, six months. Many of these cmpd are sensitive to UV light and should, therefore, be stored in the dark. The methacrylic esters may be stored in mild steel, stainless steel, or aluminum. /Methacrylic acid & derivatives/ |
用途
説明
Triethylene glycol dimethacrylate was employed to optimize the dilution of high-viscosity monomers and to link together the macromolecules constituting the polymer, to make their three-dimentional structure more rigid. It is also a crosslinking agent of acrylic resins, used in sealents or in dental bonding resins. These are mainly used in dentistry, by dental technicians and dentists.
使用
Esters of acrylic acid and methacrylic acid, more commonly known as acrylates and methacrylates are key raw materials in the coatings and printing industry, and in food packaging.
一般的な説明
Triethylene glycol dimethacrylate (TEGDMA) is a hydrophilic, low viscosity, difunctional methacrylic monomer employed as a crosslinking agent.
