Safety
Description
LOCTITE EDAG 437 E&C is a thermoplastic, highly conductive copper coating designed for EMI shielding and electrostatic discharge (ESD) protection in plastic housings of electronic and medical equipment. It can also be used as a reflective layer on parabolic antennas.
The coating provides excellent electrical conductivity (<0.5 Ω/sq), superior adhesion to common plastics (e.g., ABS, PC), and stable performance under thermal cycling. It is applied via spray and cures at room temperature, making it suitable for high-volume production.
Applications:
-
EMI and ESD shielding in consumer and medical electronics
-
Reflective coatings for parabolic antennas
-
Conductive layers on ABS, PC, and PS plastics
-
Electromagnetic protection for plastic enclosures
Technical Properties:
-
Technology: Thermoplastic copper coating
-
Appearance: Copper color
-
Sheet resistance: <0.5 Ω/sq @ 25 µm dry film
-
Pencil hardness: >9H
-
Adhesion: 5B (ASTM D3359)
-
Shielding effectiveness: 50–70 dB (at 50 µm)
-
Solid content: 63.5%
-
Viscosity: 4,500 mPa·s (20 rpm, 20°C)
-
Theoretical coverage: 23 m²/kg @ 10 µm
-
Drying: touch dry in 5 min, full properties after 24 h (RT)
-
Shelf life: 12 months (5–30°C)
