A special type of enamelled wire is selfbonding wire or bondable wire. Selfbonding wire is an enamelled with an additional adhesive enamel overcoat. This adhesive has a bonding feature, which is activated by heat or solvents. Once activated the adhesive bonds turn to turn windings into a compact self supporting coil. The use of selfbonding wire may offer cost and manufacturing advantages in some winding applications as bobbins, tape, varnishing, or impregnation may be eliminated.
