3M™ Scotch-Weld™ One-Part Epoxy Adhesive 6104 Black is a one-part epoxy engineered for nearly endless design possibilities for consumer electronics. This is made possible through its unique adhesive properties, which include low-temperature (65 °C) curing in order to bond to or near heat-sensitive substrates — while still offering fast, high-temperature (90–120 °C) curing when needed. It can be used for bonding dissimilar materials and electronic-grade plastics, ensuring low shrinkage, excellent impact resistance, and more than 70% elongation after curing for enhanced flexibility. Smartphones, tablets, wearable devices — unlock true design freedom with 3M™ Scotch-Weld™ One-Part Epoxy Adhesive 6104 Black.
To further support design innovation, 3M™ Scotch-Weld™ One-Part Epoxy Adhesive 6104 Black has been optimized to be easy to use and help reduce waste. One such feature is that both the resin and curing agent are in the mixture, with polymerization only occurring when heat is applied. There is also no mixing required and no nozzle to switch out, granting freedom to make minor dispensing adjustments and build smaller batches with less waste. Additionally, thanks to its improved bead stability, application techniques also vary — including bead dispensing, jetting, screen or stencil printing, and molding. The added benefit of room temperature stability for up to four weeks, which offers assembly flexibility, 3M™ Scotch-Weld™ One-Part Epoxy Adhesive 6104 Black is an adaptable solution for a variety of electronic bonding applications.
