The main component of silicone structural sealant is hydroxyl terminated polydimethylsiloxane, supplemented by crosslinking agents, fillers, plasticizers, coupling agents, and catalysts mixed in a vacuum state to form a paste like substance. It solidifies with water in the air at room temperature to form elastic silicone rubber.
Single component silicone glass adhesive is a type of ointment that, upon contact with moisture in the air, solidifies into a tough rubber like material. Silicone glass adhesive has strong adhesion, high tensile strength, as well as weather resistance, vibration resistance, moisture resistance, odor resistance, and adaptability to large changes in temperature and cold.
High quality silicone glass adhesive will not experience extrusion failure or changes in physical properties when used below zero degrees Celsius.
