Best glue on plastic

To bond plastic there are many different types of glues & adhesives available but which is the best glue on plastic. Can the product be used as a waterproof glue for plastic? There are also many different types of plastics including PVC, ABS, polycarbonate, Plexiglas, perspex, acrylic, polyethylene, polypropylene & polystyrene to name a few. Certain glues & adhesives perform better on certain plastics than others.

Best adhesive for plastic

Is it possible to glue plastic using an adhesive? The answer is yes, if using the record breaking strongest Adiseal adhesive & sealant.

Why Adiseal is the best adhesive for plastic

Adiseal adhesive & sealant was the strongest adhesive in an independent adhesive strength test by Ultimate Handyman.

In the independent adhesive strength test by Ultimate Handyman, Adiseal was over 3 times stronger than the nearest competitor in the wood to metal bond strength test. In fact, it was so strong that the screws holding the metal sheet down started to rip out forcing the test on Adiseal to be stopped.

Some of the other reasons why Adiseal is the best product when trying to glue plastic:

• Adiseal stays permanently flexible so it will absorb any vibration and allow any items to expand & contract without the adhesive becoming weak.
• Is waterproof glue for plastic so it is also suitable for use outdoors or indoors. It works in dry, wet & even underwater.
• Has very high gap fill properties.
• Has high initial grab meaning temporary supports may not be required while the adhesive cures. Adiseal Hi-Grab has even higher grab than the standard product.
• Is a suitable adhesive to stick most plastics.

Waterproof glue for plastic

Where plastic is exposed to water, this requires a waterproof glue for plastic. Adiseal is a waterproof adhesive that can glue plastic and remain waterproof. It can be applied on dry, damp, wet surfaces & even underwater as well.

Adiseal also seals leaks instantly, even if there is water pouring out of the hole or gap in the plastic. In the example below, we have sealed the leak in a plastic tub instantly with Adiseal. We first cut a large 1cm wide by 25cm long hole into the plastic tub. We then filled it with water. With the water pouring out of the hole, we sealed it immediately with Adiseal.

Best Glue on Plastic

Adiglue is our best glue on plastic. It’s a high-performance industrial strength glue that outperforms other glues & super glues. Adiglue provides a stronger and less brittle bond than super glues.

How is Adiglue better than super glue?

Adiglue outperforms other glues & is stronger than super glue because Adiglue is almost 100% pure cyanoacrylate. To make super glues cheaper to manufacture, most super glues are filled with solvents. This results in the super glue drying extremely quickly but leaving a weak brittle bond.

The other problem is when the solvents evaporate away, the super glue quickly dries up in the bottle. As long as the Adiglue bottle nozzle is kept clean, Adiglue will not dry up in the bottle for 18 months even if the bottle is kept open. After using Adiglue, use Adisolve sprayed on a tissue to wipe off any excess Adiglue from the bottle nozzle and keep the bottle stored in an upright position

As Adiglue is not filled up with solvents, Adiglue cures quickly but slightly slower than other super glues. This results in a bond that is a lot stronger than super glues as well as being less brittle.

Super glue gel

Adiglue has a thicker gel glue formulation which results in higher gap fill than other glues. The gel glue allows it to be used where other super glues would fail. The thicker gel formulation also makes Adiglue easier to apply & less messy than other glues.

Clear glue

Adiglue is a completely clear glue and stays clear once it has cured. This is very useful when a clear glue is required like a glue for glass.

Glue strength demonstration

To demonstrate just how strong Adiglue is compared to other super glues, we have stuck together some MDF wood blocks together with Adiglue. We have then stuck some house bricks to the MDF & to other bricks with Adiglue. This is not be possible to do with other glues.

Adiglue will bond plastic to the following items

How strong is Adiglue

Adiglue is one of the strongest glue available. The strength of Adiglue will depend on the materials it is being used to bond. On some items the strength of Adiglue is actually stronger than the material itself.

Adiglue strength example

In the example below we have sealed the edge of the MDF wood blocks using the Adiglue Activator then applied the Adiglue to stick the 2 MDF wood blocks together. Once the glue has dried, we tried to break the bond between the 2 block by stamping on it.

As seen in the image, the MDF wood has broken before the Adiglue showing the glue is stronger than the MDF wood.

Plastics that are hard to bond

Some plastics like polyethylene and polypropylene can be difficult to bond. This is because of the surface energy of the material. To be able to glue these plastics, the surface has to be treated first to change the surface energy of the plastic.

Glue plastic vs mechanical fixings

It is possible to attach plastic with either glue or mechanical fixings. Either option has advantages and disadvantages. One disadvantage to using glues to bond plastic is they can be more difficult to remove when the bond is no longer required. A disadvantage to using mechanical fixing like screws is they will leave a permanent hole in the material. The screw might also stay visible and ruin the look of the plastic. Sometimes both mechanical fixing can be used together with an adhesive or glue to make the plastic joint even stronger.
