Metal To Plastic Bonding

See the high bond strengths attainable below.

Metal to plastic bonding.

For selection purposes. 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. Ideally the coefficient of thermal expansion for the adhesive itself would be negligible. Metals and plastics have different coefficients of thermal expansion so the best glue for plastic to metal bonding will accommodate this difference.

35 n mm 5100 psi. 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. Flexible waxy polyethylene and polypropylene such as hdpe pete most buckets cups food or soda or cleaner bottles.

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. Here are my two favorites. Before attempting to glue metal to plastic it s important to know what types of adhesives can accomplish the task. Plastic that you pretty much cannot glue.

Apply the initiator to the metal and the adhesive to the plastic. Permabond ta4246 with initiator 46 is a no mix adhesive and initiator. Sand both the metal and plastic first to rough up the surface so the glue will grab. Hard plastics like acrylic abs polystyrene vinyl pvc.

Substrates and surface condition. The biggest advantage of super glue is that it s very easy to apply.
