Sealant curing itself in the air, into a sealing role of the rubber ring, the role of sealing gasket.
The glue is pasty before it solidifies, like Ivory paste, sealed with an aluminum tube bottle. When it is used, squeeze the sealant out of the aluminum tube and apply it to the surface to be sealed to make a rubber ring.
I don't know what you want to ask. Gasket free sealant is usually a room temperature curable one component silicone sealant.
