Metal To Plastic Bonding

There are metal adhesives that bond some plastics and plastic adhesives that bond some metals.

Metal to plastic bonding.

35 n mm 5100 psi. Apply the initiator to the metal and the adhesive to the 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. Substrates and surface condition.

There are several types of structural acrylic adhesives and not all bond metal to plastic. Sand both the metal and plastic first to rough up the surface so the glue will grab. Plastics that you generally can glue. Ideally the coefficient of thermal expansion for the adhesive itself would be negligible.

Permabond ta4246 with initiator 46 is a no mix adhesive and initiator. 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. 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. Flexible waxy polyethylene and polypropylene such as hdpe pete most buckets cups food or soda or cleaner bottles.

Cyanoacrylate glue more commonly known as super glue is the easiest option when dealing with metal and plastics. The biggest advantage of super glue is that it s very easy to apply. 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.

See the high bond strengths attainable below. Plastic that you pretty much cannot glue.
