Metal To Plastic Bonding

Flexible waxy polyethylene and polypropylene such as hdpe pete most buckets cups food or soda or cleaner bottles.

Metal to plastic bonding.

Plastic that you pretty much cannot glue. Plastics that you generally can glue. Sand both the metal and plastic first to rough up the surface so the glue will grab. Permabond ta4246 with initiator 46 is a no mix adhesive and initiator.

See the high bond strengths attainable below. There are several types of structural acrylic adhesives and not all bond metal to plastic. The specific substrates as well as the surface condition of the substrates the types of stresses on the bond and the environment the bond must withstand help in selecting the best adhesive. Apply the initiator to the metal and the adhesive to the plastic.

Not all adhesives are alike wood glue and school glue for instance are designed for porous materials and would not work well on either metal or plastic. For selection purposes. The biggest advantage of super glue is that it s very easy to apply. Substrates and surface condition.

There are metal adhesives that bond some plastics and plastic adhesives that bond some metals. Cyanoacrylate glue more commonly known as super glue is the easiest option when dealing with metal and plastics. Ideally the coefficient of thermal expansion for the adhesive itself would be negligible. Unlike plastic glue cyanoacrylate glue does not melt the plastic of the surface but only creates a strong layer of hardened adhesive once it dries.

Metals and plastics have different coefficients of thermal expansion so the best glue for plastic to metal bonding will accommodate this difference. Before attempting to glue metal to plastic it s important to know what types of adhesives can accomplish the task.
