Silicone sealant is a paste made of polydimethylsiloxane as the main raw material, supplemented with a crosslinking agent, filler, plasticizer, coupling agent, and catalyst in a vacuum state. Reacts with water in the air and cures to form elastic silicone rubber.
Silicone sealant is a liquid form of adhesive. Typically, it looks, feels, and acts like a gel. It has a different chemical makeup from other organic polymer-based adhesives.
