Tetramethoxymethyl Glycoluril for Negative Photoresist

Electronic Grade Tetramethoxymethyl Glycoluril (TMMGU), with CAS No. 17464-88-9 and a molecular weight of 318, is a high-end fine chemical raw material specially developed for the electronic information industry. With a purity of over 99.9% and impurity content controlled at the ppm level, it possesses both chemical stability and cross-linking activity, serving as a core key raw material for negative photoresists and semiconductor chip manufacturing. Electronic Grade Tetramethoxymethyl Glycoluril appears as a white powder with no peculiar odor, no adhesion, and good fluidity. Its melting point is precisely controlled between 105-120°C, and the formaldehyde content is ≤0.2%, which far exceeds the standards of ordinary industrial grade. It has stable physical and chemical properties, is not easily affected by temperature and humidity, and is suitable for the harsh production environment in the electronic field.

As a key electronic-grade raw material, the core advantage of Electronic Grade Tetramethoxymethyl Glycoluril lies in its precise reactivity brought by high purity and low impurities. It can efficiently cross-link with resins in the photoresist system to form a dense and stable structure, effectively improving the resolution, etching resistance, and imaging accuracy of the photoresist. In semiconductor chip manufacturing, Electronic Grade Tetramethoxymethyl Glycoluril provides reliable support for the precision photolithography process of chips, facilitating the development of chips towards miniaturization and high-density integration. In PCB manufacturing, it can enhance the insulation performance and heat resistance of circuit boards, meeting the performance requirements of high-end electronic equipment, and is widely used in high-end electronic fields such as 5G, artificial intelligence, and the Internet of Things.

Electronic Grade Tetramethoxymethyl Glycoluril adopts electronic-grade precision synthesis and multi-channel purification processes, strictly controlling pollutants such as metal impurities and particles without harmful residues. For storage, it is packaged in a sealed and moisture-proof manner, placed in a clean, dry, static-free, and dust-free environment to avoid contact with moisture and organic solvents, facilitating long-term storage and long-distance transportation. With its extreme product quality and precise performance adaptation, it has become the preferred raw material for global electronic-grade photoresist and semiconductor manufacturing enterprises.
