or cyanoacrilic resin. Synthetic resin utilized as an adhesive, characterized by its capacity to polymerize quickly under pressure, assuring a strong junction between the glued materials without creating extra width. It is able to be used on various materials, including glass and ceramics. In restoration, it is used only in cases that do not require reversibility as a priority, given that the junction is resistant to the major part of solvents, excluding dimethylformammide.
