What silicone oil is commonly used for modular LCM glue?

Module LCM glue generally uses silicon and tuffy.

Silicon is used in front of the glass pin ends to prevent ITO corrosion. TUFFY is used in the FPC soldering area opposite the glass pin end, and its function is to prevent bubbles from entering the FPC bump.

Silicone oil, whose English name is silicone oil, CAS number is 63 148-62-9, and its molecular formula is C6H 18OSi_, is a kind of polysiloxane with chain structure with different polymerization degrees. It is prepared by hydrolysis of dimethyldichlorosilane with water, and low ring is obtained by ring-opening rectification. Then the ring, sealant and catalyst are put together for telomerization to obtain mixtures with different polymerization degrees, and the low-boiling substances are removed by vacuum distillation to prepare silicone oil.
