Benefits of Master Bond's EMI/RFI Coatings
Greater use of plastic enclosures/housings in manufacturing digital electronic devices has increased the need for reliable EMI/RFI coating solutions. A range of compounds have been developed that offer different conductive fillers to provide numerous resistance and attenuation levels. These systems can be applied by brushing and conventional spray techniques.
- Protect electronic devices from electromagnetic pulses
- Superior shielding performance
- Minimal tack free time
- Cost effective alternative to other shielding methods
- Provide uniform thickness
- Exceptional point to point resistivity
- For high and low volume applications
