Conductive glue is a mix of base resin, thinner and conductive carbon powder (or metal powder). Once cured, the carbon black particles touch one another in the glue layer to form conductive paths, restoring conduction to contacts that were open or poorly connected. Compared with silver paste conductive adhesives, carbon-based conductive glue costs less and bonds strongly, suiting contact repair in consumer electronics.
Specifications
| Item | Specification |

Applications
| Application | Description |
|---|---|
| Remote control buttons | Restores conduction when worn conductive rubber contacts stop working |
| Membrane keyboard contacts | Repairs worn printed conductive layers on membrane keyboards |
| Electronic keyboard keys | Repairs failed key contacts |
| LED strip contacts | Patches breaks to restore the conductive connection |
| Ceramic capacitor bonding | Bonding capacitors in calculators and similar devices |
| Game controllers | Repairs direction and function key contacts |
Notes for use: shake well before use (the liquid separates when left standing, which is normal). Apply thinly; thick coats lengthen curing. Avoid contact with eyes; if contact occurs, rinse with water at once. Keep parts fixed in position while curing.
Note: cured conductive glue conducts stably but is not a low-resistance conductor; it suits low-current contact repair, not high-current or high-frequency circuits.
Common questions
Can conductive glue repair a remote control button? Yes. It restores conduction on worn conductive rubber contacts; it is meant for low-current contacts, not high-current or high-frequency circuits.
