Composed of silicone or urethane materials, sealants are used to close small gaps between surfaces such as glass, wood, brick, varying types of stone, tile, and rigid plastic surfaces with an airtight seal. Sealants can be described as higher-strength, adhesive-derived or as low-strength putties, waxes, and caulks. Varying properties include weakness or strength as well as flexibility and rigidness. Sealants serve as a barrier against water, air, temperature, noise, dust, insects, and in some cases as a fire retardant. Sealants are classified by their physical form into three categories: one-component, two-component, and sealant tape.
