Let’s unravel the mystery of these metallic or conductive additives and discover how they work their magic. One common additive found in conductive glues is silver particles. Renowned for its exceptional conductivity, silver effortlessly carries electrical current. When these minuscule silver particles are introduced into the glue, they create a network that forms a conductive path within the adhesive, enabling it to conduct electricity with ease.
But silver is not the sole star of the show. Other additives such as carbon black, copper particles, and even graphene have emerged as key players in certain conductive glues. These additives operate in a similar fashion by constructing pathways for electrical current to flow through the glue, expanding the possibilities of conductive applications.
Before you race to your nearest craft store in search of conductive Elmer’s glue, it’s important to note that not all Elmer’s glues possess these magical properties. The standard white glue cherished for its bonding abilities is not conductive.
