Sealant

In aviation, a sealant is a type of adhesive used to fill gaps, cracks, and joints in aircraft structures to prevent the ingress of water, air, and other contaminants. Sealants are used in various parts of an aircraft, including fuel tanks, windows, doors, and seams. They are designed to withstand the harsh conditions of flight, including changes in temperature, pressure, and vibration. Sealants can be classified into two types: cured and non-cured. Cured sealants harden after application, while non-cured sealants remain flexible. The selection of sealant depends on the specific application and the materials being joined.
