This video simply shows that “wire glue” (a conductive glue/adhesive) does conduct electrical current.
Many product reviews stated that it does not conduct current, and/or was too runny and did not adhere like a glue. All of these assertions were found to be false. Wire glue did conduct current. It can be loose or runny but can be thicken if left open to the air. Conversely, water can be added to thin it. Wire glue does solidify (set) given enough dry time. Parts to be glued must be held into position (taped for example) until wire glue sets. It is recommended that a wire glue joint be reinforced with an epoxy coat.
Another criticism was that use of conductive glue (as opposed to soldering) is an immature approach or only used when soldering skills are lacking. However, conductive glues are tools of sort, and like all tools, conductive glues have there own place.
The use of conductive adhesives is an acceptable method, and an alternative to soldering; whereby, an electrical connection is needed when heat is not appreciated nor tolerable such as near plastics, detrimental to wire sheathing and/or other heat sensitive materials. etc. The manufacture of conductive adhesives is a billion dollar industry, involving numerous chemically based conductive compounds. Some of the most highly conductive compounds are extremely expensive such as aluminum epoxy, nickel epoxy, silver epoxy, up to gold epoxy.
The conductive glue used in this video [Wire Glue] is for low voltage. It is a low-cost, water based graphite compound but still performs well in general application. Wire Glue, like all conductive glues, has some resistance but that resistance was unnoticed. In this project, LEDs wired using wire glue achieved the CORRECT and desired forward current as it related to the other Ohm’s law factors, power supply and forward voltage (tested with a Fluke 115 RMS multimeter).
