Among various types of organosilicon sealants, ketoxime – type organosilicon sealants once had certain application scenarios. However, they have obvious defects: the by – products released after curing have an unpleasant odor, and they are corrosive to metallic copper and polycarbonate plastics, which greatly limits their applications.

In contrast, alcohol – removing sealants show significant advantages. Since the products released after their curing are neutral alcohols, which are non – corrosive to both metals and plastics, they have been paid more and more attention by the industry.

Early alcohol – removing sealants put into the market mainly used amino silane or organic tin as catalysts. However, these two catalysts have shortcomings such as strong odor and easy yellowing, which affect the product quality and application scope to a certain extent.

In recent 10 years, developed countries such as the United States and Japan have made important progress in the research, development and application of alcohol – removing sealants. They have gradually adopted titanate complexes as catalysts. This kind of catalyst not only has excellent adhesiveness, but also is harmless to human bodies and the environment. Relying on these advantages, alcohol – removing sealants using titanate complexes as catalysts have become the mainstream products in the high – end electronics industry.

With the continuous progress of science and technology and the change of market demands, alcohol – removing organosilicon sealants are expected to obtain broader applications and development in the future. Relevant Chinese enterprises are also actively carrying out the research and application of titanate complex catalysts, and are committed to improving the technical level and market competitiveness of alcohol – removing sealants in China. At present, a relatively mature product is the titanate sealant of Jiutian Quantum.
