Shanghai Yongji Chemical Technologies, Inc. (Yongji chemical) is a technology company focused on the research, development and production of fine cleaning agents. We are located in the Shanghai Incubator of Fine Chemical Industrial Base, Jinshan District. We are the first company to start operations there. We have representative offices in Suzhou , Shenzhen and other locations.
Yongji Chemical and its predecessor company have a total of 10 years of professional electronics cleaning agent research, development and manufacturing experience. After more than three years of persistent efforts, we have developed the CYC series of water-based cleaning agents employing the CPT®technology. We have full ownership of intellectual property rights, which are at par with advanced world level, on these products. This series of cleaning agents is characterized by having strong cleaning power, safe and environmentally friendly. They can be recycled to achieve integrated low-cost applications. This cost-performance has won them the position of being the most widely used and ideal alternative to upgrade and replace organic cleaning agents and ionic detergents. They can be used in electronics, IC, LCD, automobiles, aircraft and other high-end cleaning areas.
We want to work with you to make “Yongji Chemical” a world-wide success.
CPT - Complex Phase Technology works on the principle of phase change between different liquids and is different from traditional cleansers which are based on saponification granules. CPT works, when under the influence external force, generating strong bonds between cleaning agent's activated molecules and contaminant molecules. When this external force stops, these activated molecules will release the bond between them and contaminant molecules, hence recyclable. The technology has high penetration power which is particularly suitable for use in high-density and precision products. Yonji Chemical's series of water-based cleaning agents, CYC, which employs the CPT®technology, has 10-20 times as much cleansing capacity as traditional cleansing agents. High cleaning power and recyclability give our product excellent cost/performance ratio. Low volatility and low flash point are the safety factors gives additional cost savings by not requiring dangerous goods storage facility and expensive ventilation equipment which are required for solvent-based cleaning agents. The eco-friendliness of our CYC series helps enterprises to satisfy ISO-14001 environmental requirements.
