3M™ ACF 7303 is an epoxy/acrylate-blend adhesive system filled with 43 micron silver-coated glass beads. It is slightly tacky at room temperature and cures at modest bonding temperature and pressure.

The unbonded film is slightly tacky at room temperature and consists of a thermoset-elastomer and thermoplastic adhesive matrix randomly loaded with conductive particles. These particles allow interconnection of circuit lines through the adhesive thickness, but are spaced far enough apart for the product to be electrically insulating in the plane of the adhesive. Soft conductive particles are preferred when bonding to fragile substrates such as ITO on glass, as they deform against hard surfaces, but may also be used for other substrate types. 3M™ ACF 7379 may be used to bond a flexible printed circuit to glass-based devices such as displays or to another flexible printed circuit.
