Problems solved by technology

The disadvantage is that the reactant system is viscous, difficult to stir, and the molar mass uniformity of the product is poor
The technology of continuous production of 107 glue is not yet mature. Chenguang Chemical Research Institute can only produce methyl or vinyl-capped polydimethylsiloxane using twin-screw technology, but cannot produce hydroxyl-capped polydimethylsiloxane. Methylsiloxane 107 glue
