Which types of glue are most effective for binding plastic to metal?

The most effective type of glue for bonding metal to plastic depends on the types of metal and plastic to be bonded together. Polyurethane adhesives usually work well for bonding a wide variety of surfaces, including plastic and metal.

Cyanoacrylate adhesives, such as Super Glue, can also be effective for bonding metal to most types of plastic but are not recommended for bonding foamed plastic. Pressure sensitive adhesives, which are available in sheets or dots, are effective for bonding light-weight metal and plastic, whereas contact adhesives, applied with a brush or roller, are most effective for larger metal and plastic sheet laminates.
