Best Glue For Plastic [Reviews+Buyer's Guide]

With so many types of glues available, it can be hard to determine which is the right one for the job. Most plastics are pretty flexible, which can, in turn, affect the strength of the bond. However, certain glues and adhesives have been formulated explicitly with the nature of plastic in mind.

Whether you are working on a large project like repairing boats or a smaller craft project, using the right adhesive can make a world of difference. And to help you find the best glues for a plastic surface, we have compiled the top options as well as a guide on how to pick the best one.

With that being said, let’s get into it!

Best Glue For Plastic

So whether you're repairing a broken plastic item or creating a new plastic project, you can be confident that these glues will do the job right. Without further ado, here's the list of the 7 best glue for plastic.

1. Gorilla - Best Overall

Making repairs and fixing chips and cracks is a cinch with this Gorilla super glue at your side. It can be used on various materials, acting as either wood glue or plastic glue, making it a truly multi-purpose option.

Why Did We Like It?

Working with the Gorilla super glue was a breeze, thanks to its thick formula. Most glues have a thin consistency that makes applications a bit messy at times. But we didn’t face any issues while applying this one on plastics and different materials, even for vertical orientations.

Another handy feature is an accessory that Gorilla included in their glue sets. A metal tip helps keep the nozzle free from buildup. Of course, the amount of buildup is also controlled by the anti-clog design of the tip, unlike other adhesives that can prevent any glue from coming out of the package.

As for the strength of the glue, it is a potent adhesive that can bond in no time at all. Gorilla claims that the glue can achieve a strong bond in less than a minute. This means no clamping is required to fully cure the glue.

What Could've Been Better?

Although the Gorilla glue has a thick consistency, it can impact its accuracy on the target material. This is mainly due to the design of the bottle which is difficult to wield with one hand to get the glue out.

Pros

Why Did We Like It?

Truly a one-of-a-kind bottle design, the brush attached to the bottom of the bottle’s lid does come in handy when applying the adhesive. For one, it makes covering a larger area much more accessible than using traditional methods. It can also be spread better and evenly, so the bonding strength is pushed to its full potential.

Furthermore, the bottle design of the superglue limits the frequency of clogs. A tight fit on the lid ensures the glue doesn’t dry out prematurely. As an extra layer of security against clogging, the bristles on the brush are designed to not bunch together into clumps.

As for the application process of this super glue, it couldn’t be more straightforward. Simply dip the brush into the formula, then run it across the surface. The brush does all the work of making an even layer, giving you more control over where it is being applied.

What Could've Been Better?

While using a brush as an applicator can have its perks, it also limits the bottle to this single method. There were instances of the brush becoming detached, in which case the formula becomes inaccessible without a precise nozzle for application. This risk should be considered if you are contemplating using this method of application.

Pros

Simple application
Reduced frequency of clogging
Wide surface coverage
Bristles don’t clump up

Cons

Brush adhesion can come undone

Keeping the curing time to a minimum is another one of the benefits of using this adhesive. The workflow can be kept moving without having to wait for the adhesive to fully cure.

What Could've Been Better?

As stated before, all that is needed to pull the formula from the container is a pinch with varying degrees of pressure. Combined with the low viscosity, this feature can cause cases where the adhesive is prematurely ejected and cause a mess. Hence, caution should be practiced while using this particular adhesive.

Pros

Fast curing time
Durable, lasting bond
Low viscosity formula
Precise application

Cons

Formula is ejected quickly

Buying Guide For The Best Glue For Plastic

The best plastic glue is the one that can form a solid bond that lasts. Before you settle on a particular adhesive, there are a few factors to consider to find the right glue for your use. To ensure you have the best quality bond, keep these factors in mind while making your decision.

1. Types Of Adhesives

Among the many adhesives on the market, there are mainly two camps that plastic glue options fall under. The first is epoxy adhesives that demand more attention in the application. The second would be standard superglues that are comparatively easier to use and apply.

Plastic bonding using an epoxy putty mixture can be challenging for those who are unfamiliar with the procedure. However, there are specially designed bottles that can aid novices by mixing the proper ratio for them.

On the other hand, super glues make for a much simpler plastic bonding experience. As far as the various application processes of glue for plastic, this is relatively straightforward. Simply uncap the nozzle and apply the formula to the desired surface.

2. Durability

Tensile strength and various resistance to external factors are crucial features to look out for in adhesives. An impact-resistant bond, for example, keeps the plastic parts together even when exposed to trauma. Sealants are a type of adhesive that can be applied to the surface of the material to add increased durability and resistance against specific factors.

Additionally, a water-resistant adhesion is a valuable feature to have, especially on a non-porous material like plastic. A water-resistant glue for plastic acts as a barrier to protect the underlying material.

While heat may be essential to fully cure the adhesive, too much can distort the plastic. That is why a heat-resistant formula is recommended if the treated surface is to be exposed to high temperatures.

3. Ease Of Use

Factors like how easily the adhesive can be cleaned up and the time taken to dry can significantly impact the user experience. Depending on your needs, these features can be adjusted to find a suitable match for you.

Among adhesives, there are various degrees of drying and curing times involved. There is a rubber instant adhesive on one end of the spectrum that can chemically bond and dry instantaneously. On the other end, some glues may take a few hours to fully cure.

The glue dries at different speeds, depending on the flexibility of the material. With more flexible surfaces like fabric and plastic, the material must be broken down to some degree to attain a strong bond.

Furthermore, cleaning up excess applications of these adhesives can be a chore if you are not careful. Common methods include mineral spirits and denatured alcohol that are rubbed on after the glue dries. Steel wool or warm soap water are other popular cleaning methods used on other materials to have a more professional, finished look.

Glue For Plastics FAQs

Hot glue can be used on some types of plastic, but it may not be the best choice for all applications. It is great for bonding two surfaces quickly but may not hold up well over time if the plastic is exposed to moisture or high temperatures. For a stronger bond, consider using epoxy glue.

For bonding plastic to metal, a strong and durable adhesive is recommended. Epoxy glue is a good choice for this application as it forms a strong bond between the two materials.

Yes, superglue can be used on plastic. However, it may not be the best choice for all types of plastic as it can become brittle over time and may not hold up well under stress. For a stronger bond, consider using epoxy glue.

To remove glue from plastic, you can use a solvent such as acetone or rubbing alcohol. Apply the solvent to the glue and allow it to sit for a few minutes. Then, use a scraper or a cloth to remove the glue. Be sure to wear gloves and work in a well-ventilated area.

Welding is not an option for bonding plastic as it can melt the plastic and cause damage. Glue is often the best option for bonding plastic. However, some plastics can be heat-welded using specialized equipment and techniques.

Conclusion

Hopefully, you now know a bit more about the different types of plastic bonder adhesives available and how to choose the best one. Finding high-quality glue and creating permanent bonds to adhere to plastic can be challenging. All that is left now is to choose the right one for you.

Our all-around choice has to go to the Gorilla Glue for a thicker formula that is easy to apply and stumps many adhesives. However, if you are looking for epoxy, the self-mixing Loctite bottle design is effortless to work with.

Whether you are looking for a quick repair or a long-term project, suitable glue in the right hands can make all the difference. Invest in the proper tools, and you’ll be sure to get the job done in no time at all!
