When applied to clean, moisture-free surfaces such as copper, aluminum, ceramic, steel, tin or glass, Novec EGC-1700 coating dries to leave a thin transparent film with excellent anti-wetting, anti-stiction, anti-migration and anti-corrosion properties.
EGC-1720 is designed to covalently bond to glass and metal oxides layers forming easy to clean anti-smudge surfaces.
This makes it useful as a coating for a variety of applications, including :
- Printed circuit boards
- MR heads
- Micro motors
- Ball bearing tracks
- MEMS
- Ink jet print cartridges
- Various hard disk drive components
- TFT-LCD
The low surface energy film produced by Novec EGC coatings repel liquids such as lubricating oils, silicones and photoresist solutions used in the manufacturing of semiconductors. Novec EGC coatings are easy to apply, requires no masking and air-dry in seconds.
