Liquid silica gel is divided into two components of liquid silica gel and condensation type of liquid silica gel, the ratio of liquid silica gel is one to one, the ratio of condensed liquid silica gel is about one hundred to two. Whether the liquid silicone or condensation type of liquid silicone, their main components are 107 base glue, silicone oil, silica, etc. According to the type and proportion of various materials to change the basic characteristics of liquid silica gel, such as the hardness of silica gel, silica gel viscosity and so on.

So does liquid silicone contain water? The answer is yes. In the production process of liquid silica gel, it is necessary to add some water to produce.

Some liquid silica gel is stored for a long time, the water inside the silica gel will slowly evaporate, resulting in the increase of the viscosity of the liquid silica gel, which is often said to be thickened. The evaporation of water inside the liquid silica gel directly causes the fluidity of the silica gel to deteriorate and become difficult to operate. So one question is, what happens when you add water to the liquid silicone when it's thick?

In fact, the moisture content of the liquid silica gel is a peak, rather than just add water into the line, the moisture content of the liquid silica gel is very small. Can water be added to liquid silica gel before operation? In which case can silicone add water, which case can not add water?

Condensed liquid silica gel in dry weather or moisture shortage, according to the proportion of adding 2-3% of the curing agent, silica gel will show the phenomenon of dry surface dry. Whenever this happens, the simplest solution is to add 2-3 drops of water to the silica gel, and after fully stirring, the silica gel mold can be completely cured, and the toughness of the silica gel mold can reach the peak.

Food grade liquid silica gel is more special, because the molding of silica gel is not by moisture curing, but by temperature curing. But when the silica gel is added with water, the silica gel will not solidify. Because the impurities in the water will directly cause the platinum catalyst to be contaminated and the silica gel can not cure. When the liquid silica gel is thickened, it is not possible to add water naturally, and the appropriate silicone oil must be added to stir it.
