Why does mold silicone appear to be dry on the surface and not dry on the inside

As is well known, mold silicone belongs to condensed silicone, which is equivalent to an adsorbent that solidifies by absorbing water from the air. During the production process of silicone, if the water is evaporated to dryness without adding an appropriate amount of water, this phenomenon will occur. At the same time, if it is in winter, the curing time of the mold silicone will be very slow, especially in the north. As the winter temperature gradually decreases and the weather becomes dry, customers may experience a phenomenon of dry surface and not dry inside during operation.best liquid silicone for mold making

The phenomenon of mold silicone not drying on the surface and inside is not a problem with the quality of the product itself, but rather due to the lack of control of water content, improving the storage life of the silicone, and the long shelf life. As long as the silicone is used, an appropriate amount of 0.05% water is added, using ordinary boiling or warm water, and adding 0.1% of it to component A of the silicone, that is, about 25-30g of water is added to a 25kg package of silicone, Even more thorough stirring can solve some problems.
