bonnet are increasing and geographical locations can also produce extremes in the other direction - these extreme thermal cycles induce stress and the possibility of component failure. To add to it there is mechanical stress as a direct result of vibration derived from the engine and road conditions. Chemical and oil attack are also common in and around the engine compartment, with water and humidity a constant threat. All these factors make component protection a high priority for any electronic design engineer working within the automotive industry.
The sealing of the powertrain, water and fuel systems require strong, flexible, temperature and fuel resistant sealants. Thermally conductive silicone adhesives, encapsulants, gels, greases and gap fillers will perform this important task. Major applications include
- 1. Bonding and encapsulation of electric motors
- 2. Bonding and encapsulation of low-voltage batteries
- 3. Bonding and encapsulation of sensors and automotive electronics.
