A special type of enamelled wire is selfbonding wire or bondable wire. Selfbonding wire is an enamelled wire as described under Enamelled Wire Types, 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.
