Description of 1,3,4,6-Tetrakis(methoxymethyl)glycoluril
1,3,4,6-Tetrakis(methoxymethyl)glycoluril (CAS: 17464-88-9), commonly known as tetramethoxymethyl glycoluril or TMGU, is a versatile crosslinking agent derived from glycoluril. In polymer chemistry, TMGU serves as a reactive crosslinker in amino resin systems, enhancing hardness, adhesion, and chemical resistance in powder coatings, automotive finishes, and textile treatments. Its low formaldehyde emission makes it ideal for eco-friendly formulations.
Application of 1,3,4,6-Tetrakis(methoxymethyl)glycoluril
1,3,4,6-Tetrakis(methoxymethyl)glycoluril (TMGU) is a highly efficient, low-formaldehyde crosslinker in amino resin systems, valued for its reactivity and compatibility in thermoset formulations. In powder coatings, it enhances durability, adhesion, and corrosion resistance for indoor/outdoor applications like computer housings, automotive parts, and metal substrates. For microelectronics, TMGU serves as a crosslinking agent in photoresists and antireflective coatings, supporting fabrication of printed circuit boards, integrated circuits, flat panel displays (LCD/OLED), MEMS devices, and sensors. It also enables hydrogel synthesis for biomedical uses and surface immobilization on polyvinyl or magnesium oxide substrates. As an organic synthesis intermediate, it aids in developing eco-friendly resins.
Storage of 1,3,4,6-Tetrakis(methoxymethyl)glycoluril
It should be kept in a cool, dry, well-ventilated area at room temperature in sealed containers to prevent moisture absorption, which may lead to hydrolysis. Protect from light and humidity using desiccators or airtight packaging. For long-term stability, refrigerate at 2-8°C under inert atmosphere if available. Avoid exposure to strong acids or bases.
