n-Butyltrimethoxysilane (BTMS) is a silane compound that is used in various industrial and scientific applications, from the synthesis of polymers to surface treatment of materials. For example, it is used in the production of lubricants, adhesives, and coatings, as well as to modify the surface of polymers, metals, and ceramics. Its action is based on the formation of a siloxane bond between the silane and the hydroxyl groups on the surface of the material.
