Self-adhesive enameled wire is on the surface of conventional enameled wire, coated with a layer of self-adhesive paint, cured self-adhesive paint can be melted by ethanol melting, high-temperature melting to achieve the second melting, so as to achieve the adhesion between adjacent enameled wires.


Due to the winding of the bonding of most of the drip paint or dip paint process, the process of solvent volatilization caused by serious environmental problems, so in developed countries more use of self-bonding wire. With the development of China's economy and the importance of environmental protection, the demand for self-bonding wire is also increasing.
Alcohol-fused self-bonding wires are commonly used for bonnetless coils such as voice coils and deflection coils, where the temperature resistance level is relatively low, and where the coil needs to be in motion and is weight-sensitive, which is very advantageous. The enameled wire passes through a felt impregnated with an alcoholic solvent (usually ethanol) before being wound to the model, the fused layer is melted, and the wound coil is naturally air-dried or dried and shaped.


High-temperature self-adhesive enameled wires, which utilize hot air or generate heat by energizing the conductor to achieve secondary fusion, are most widely used in the stator windings of power tools.
Most self-adhesive coatings are composed of polyamide (nylon) or modified aromatic polyamides, and compounding nylon coatings over insulating coatings results in a reduction in the softening breakdown properties of the enameled wire, which is a result of the lower thermoplasticity of nylon. In power tools, self-adhesive wires are mainly used in the stator, the stator windings are subjected to a relatively small impact, so even in the case of overload, the force between the wires is small, and the decrease in softening breakdown performance is almost unaffected. However, the excellent ductility of nylon will improve the thermal shock resistance of the enameled wire, thus enhancing the operating life of the insulation at the rated temperature.
During the winding process, when the enameled wire insulation is subjected to large scraping force, the insulation may break. The rigid structure of the insulation layer can easily lead to a situation where the insulation breaks from the outside to the inside, thus leading to the risk of turn-to-turn failure. The slippery nature of nylon is conducive to reducing winding damage, even in the case of damage, the ductility of nylon can reduce the impact of external forces and reduce the damage to the insulation layer, ensuring the reliability of the insulation.
