In the production of additive liquid glue, the terminal vinyl silicone oil used for the transparent liquid silicone rubber base polymer must completely exclude the silicon hydroxyl terminated polymer to avoid the possibility of the silicon-hydroxyl terminated polymer at elevated temperatures. The occurrence of tripping degradation affects the heat resistance of silicone rubber; the elimination of silicon-hydroxyl can also ensure the normal reaction of platinum-catalyzed silicon-vinyl and silicon-hydrogen addition reaction, avoiding the condensation dehydrogenation of silicon-hydrogen and silicon-hydroxyl The reaction is carried out to eliminate the light transmission property of the silicone rubber due to the hydrogen component.

According to the process performance and performance requirements of the finished silicone rubber, the molar mass and distribution of the base polymer must meet specific requirements. The rubber compound after filling the reinforcing silicone resin can reach the proper viscosity, and the silicone rubber after curing The required mechanical strength.
