Most of the silicone in the impression is relatively viscous, and it feels difficult to spray. Generally, most of the operations are pouring or painting.
If there is demand, there will be a market. For example, many high-performance silicone bags are made by spraying in order to obtain a more uniform thickness and less bubbles. Especially for the production of some special-shaped and larger parts, the spraying operation is extremely advantageous, but this will have certain restrictions on the silicone spraying equipment, and the conventional spray gun is obviously not acceptable. At the same time, this has some special requirements for some properties of silica gel.
