Self bonding wire with a polyvinylbutyral bond coat is easy to process and is used in a wide range of applications. The two major advantages of this adhesive type are its low bonding temperature which is required to bond the coils, and it's wide processing window.
|Chemical base of selfbonding enamel||Selfbonding type||Suitability of bonding methods||Recommended bonding conditions||Features||Applications|
|Hot air||Oven||Solvent||Elec. current||Oven bonding temperature||Solvent type|
|Polyvinylbutyral||Polyvinylbutyral||AB||++||++||+||++||130°C||Ethanol, Methanol||Low bonding temperature, wide process window, non-hygroscopic, low priced||Stepping motors in quartz watches, instruments, voice coils, sensors, RFID and Transponders|
|Polyvinylbutyral||BB||--||--||++||--||N/A||ethanol methanol||solvent bonding type, slightly higher resoftening temperature than AB||same as AB|
|Polyvinylbutyral||CB||--||--||++||--||N/A||Ethanol Methanol||solvent bonding type, fast drying||Stepping motors, other small motors, sensors, transponder, receiver, headphones|
