Mercaptosilanes are functional silicone compounds that typically contain a hydrolysable alkoxy group and a reactive mercapto group. Mercaptosilanes act as a bridge between organic resins and inorganic substrates. This makes it functional for coupling, crosslinking and surface modification.

It is mainly used as an adhesion promoter, surface modifier, and cross-linking agent, and can improve the adhesion of organic and inorganic composites such as semiconductor encapsulation materials.

In terms of applications, mercaptosilane can improve the adhesion of organic inorganic composite materials, such as in semiconductor encapsulation materials to improve adhesion strength. In addition, it can be used in the preparation of hydrophilic self-assembled monomolecular layers and as an unmasked linker molecule in the chemical and enzymatic synthesis of oligosaccharides.

As an important organosilicon compound, mercaptosilane plays a key role in the field of materials science, especially in improving the properties of composite materials with a wide range of applications.
