What is the purpose of diluting liquid silica gel?

One of the reasons for dilution: the main components of liquid silica gel are silica, silicone oil, 107 base rubber and other raw materials; but many manufacturers to reduce production costs, a large number of white carbon black (white carbon black cost is the lowest, add more powder less oiling, the overall cost is reduced, but the quality is also reduced) , resulting in a great reduction in the fluidity of liquid silica gel, high viscosity; This high viscosity, no liquidity of the liquid mold silicone is not convenient for customer operation, exhaust bubbles are very difficult, low yield.
