Plastic is ingenious, isn’t it? You want to have the best glue for plastic that should be in every crafter’s tool box. As a household item, plastic is ultra-east and strong. It contributes to waste and can be harmful to the environment.
Finding the right glue that can stick to plastic is not easy.
We’ll look at the best glue for plastic. You want to know how to choose the right glue for your next DIY project. You’ll also learn about the best plastic glues on the market.
What Is Plastic Glue?
The history of glue can be traced back to 40,000 years ago, yet the origin is unknown. Plastic glue is super glue. It’s also known as poly cement. The glue contains corrosive and flammable chemicals and is also poisonous.
Methyl Ethel Ketone (MEK) is the main ingredient of plastic glue. If you’ve ever built a plastic airplane model, then you know how strong plastic glue is. The best glues for plastic are super glue, epoxy, or solvent cement. The corrosive compounds in super glue connect plastic pieces by melting them together. That’s how strong plastic glue is.
For DIY household projects, plastic glue is the best. If you have a tube at home, make sure it’s out of reach of children.
Differences Between Plastic Glue and Regular Glue
This is simple: plastic glue is dangerous. It is against the law to buy plastic glue if you’re under the age of 18. It’s also addictive and a gateway drug.
Regular glue is for children. It’s also harmless and non-toxic.
Types Of Glue For Plastic
Not all glue types work well with plastic, but there are three that stand out:
Cyanoacrylate (Super Glue)
Super glue is the favorite, and for good reasons. It’s effective at bonding to a huge range of surfaces and materials, from wood to metal. But it does have its Achilles’ heel: plastic. The majority of super glues on do a poor job when used with plastic, though you can find a few designed with plastic use in mind.
Epoxy
Epoxies are favored over super glue when working with plastic. They use a two-part formula (resin and hardener) that creates a much stronger bond on most materials—even for some plastics.
Model Cement
Model cement is the go-to adhesive for plastic—plastic is kind of what it does. This type of adhesive also uses a two-part formula (solvents and filler), and the two parts work together to melt and then bond the plastic.
The downside is it cannot be used with other materials, so purchase this type if you have a lot of plastic bonding to do or an important DIY project.
How To Choose The Right Glue For The Job
When choosing the best glue for a DIY home project, consider two key components: your target material and project scale.
Target Material
Before shopping for glue, ask which materials you need to bond. In this case, you need to bond plastic. With this in mind, ask:
- Am I bonding plastic with plastic, or plastic with something else?
- Which type of plastic am I using?
The type of glue depends if you’re bonding plastic with plastic, or plastic with a different material. This is because the surfaces of plastic and other materials are different. Plastic is nonporous and other materials have various porosity levels. To bond materials, you need a special glue that chemically bonds to each material.
You need to know the type of plastic you’re working with because not all glues are good for all plastics. PP and PE plastics are difficult to bond, due to their hard and smooth surfaces.

These will require a formulated plastic glue to bond. Two other plastic types include:
- PVC (Polyvinyl Chloride) – connecting pipes.
- PS (Polystyrene) – for household items like plastic bowls or food packaging.
- PMMA (Acrylic) – a substitute for glass in screens and windows
Remember: Any type of plastic is easier to bond when it’s clean and sanded.
Scale Of Project
As with most tools and materials, its use should influence which one you need to buy. In this case, you need to determine:
- How important is the project I’m working on?
- What is the quality of the materials I’m using?
- How often will I be using this glue?
Your answer will determine which glue is best for you and your DIY project.
If your project is important and consists of quality materials, you should opt for a higher-quality glue. You should also ensure that whichever glue you pick will serve its purpose. The glue should work well on the type of plastic you’re using.
The same applies to the final question. If you plan on using this glue or adhesive often, it’s crucial that you get a high-quality glue you can rely on over the long haul.
What Is The Best Glue For Plastic?
There are many varieties of plastic glue. Before you choose one, learn everything you can about the different glues.
Adhesive Glue
Adhesive is a general term for super glue. When connecting two pieces of plastic, adhesive glue is the best and most powerful.
Now that you know more about super glue, you need to know the best types to use for plastic, and how to use them.
Feel free to bookmark the products for future reference.
Gorilla Super Glue
Gorilla Super Glue is great for multiple surfaces and vertical applications. It’s good for long-lasting DIY repair jobs. It can dry in 10-45 seconds. This super glue gel absorbs drops and impacts. It also works with metal, stone, ceramic, paper, and rubber. However, it is not recommended for foam surfaces.
As you’re already familiar with the Gorilla Glue brand, now, it’s time to try it out. You can use this glue to bind a number of materials (including plastic) with a high degree of strength.
The formula makes use of rubber particles which lend the bond an extra dose of resilience and strength. It dries in as little as 15 seconds and cures in a day.
When repairing smaller indoor objects, you can’t get much better than Gorilla Super Glue.
Is Gorilla Glue Waterproof?
Yes, Gorilla Glue is waterproof. After you’ve connected two pieces of plastic, let them sit for 24 hours. After the glue has cured, it can withstand water.
Gorilla Glue vs. Super Glue
After you know what surface you’ll be working with, then you can determine which glue to use, Gorilla glue or super glue.
Gorilla glue is ideal for smooth and porous surfaces. For example, glass, ceramics, and wood. You can use glue to connect two pieces of metal. It’s also known for its long-lasting qualities. Outdoor DIY projects or ones that require water resistance, as the glue is 100 percent waterproof, would work well. It can also withstand high outdoor temperatures, so heat isn’t a problem.
Super glue is not as powerful as Gorilla Glue. However, it dries fast and has strong adhesive qualities.
It works on most surfaces, but there are exceptions. For example, super glue doesn’t work on smooth surfaces like glass. It also won’t work on porous surfaces like wood.
How To Get Gorilla Super Glue Off Skin
If you get Gorilla super glue on your skin, you’ll need to remove it asap. A good DIY home remedy would be acetone. All you need to do is soak the skin that has glue on it with acetone. You can also use cotton swabs to wipe it off your skin.
Your child comes to you with tears in their eyes, lips pouting, holding their favorite toy and you see that it’s broken. What can you do to stop your child from crying?
By telling them it’s okay, grabbing your handy bottle of Gorilla Super Glue, and fixing the problem then and there.
Loctite Super Glue
Loctite Super Glue is unlike any glue on the market. The glue has a patented additive that can bond materials in ways that other glues can’t. The glue is the first choice among metalworkers when bonding metal. It is also effective on porous and non-porous surfaces. If you have a DIY project that requires you to fix broken metal items, then this is the glue you want to use.
The company is legendary among super glue manufacturers worldwide.. In 2009, the company set a Guinness World Record by lifting a five-ton automobile with nine drops of its cyanoacrylate adhesive.
Most epoxy adhesives require mixing the two parts, but not the Epoxy Instant Mix from Loctite. The formula mixes while in the dispenser. It has a PSI rating of 3,200. It serves as a stronger filler for small DIY projects.

Rhino Glue
Rhino is a commercial grade adhesive that, according to its website, “bonds anything to anything.” The glue is the result of 14 years of research and laboratory testing. It is ideal for DIY household and office projects.
With a name like “Rhino Glue,” you know it’s tough. Its strength and longevity are due in part to its triple-distilled adhesive formula—but its resistance to impacts, shock, vibration, moisture, and heat helps too.
You can apply it to several materials. It will bond in seconds with a reliable iron grip.
Rhino Glue Pro Kit
If you’ve wondered why you haven’t seen Rhino glue on the shelves at your local hardware store it’s because the glue is not available over the counter. You can, however, order their glue online.
The Rhino Glue Pro kit includes 40 grams of Rhino glue, 15 grams of Rhino gel, and a brush with 10 grams of plastic glue goodness packed inside. If that doesn’t scream “Father’s Day gift,” then nothing else does.
3M Glue
The three M’s in 3M stand for Minnesota Mining and Manufacturing Company. Even though the word “glue” isn’t part of the three M’s, that doesn’t they don’t know how to make plastic glue.
Glue should not be hard to use. Here, we’re talking about high-strength, glue-your-eyelids-shut type. 3M gets this and has a formulated adhesive. It has a pinch bottle so the gluing process runs smooth.
The adhesive has a low viscosity, a PSI rating of 2,000, and fast hardening and cure times. It’s great for binding most materials, and can bind to PP (polypropylene) and PE (polyethene) when used with a primer.
Strength, versatility, ease of use, things you should look for in plastic glue.
3M Adhesive
Have you ever wondered why an adhesive will stick to a surface? 3M understands the science of adhesiveness. There are four methods through which adhesives bond to a substrate surface.
- Chemical Adhesion – This is the strongest attribute of adhesion. It is here when the bonding occurs between groups in the adhesive and molecular substrate surface.
- Mechanical Interlocking Adhesion – occurs as the adhesive flows into the pores on of the surface.
- Diffusion Adhesion – adhesive molecules penetrate the surface by bending and stretching.
- Electrostatic Adhesion – this is when both surfaces are joined.
Krazy Glue
Krazy Glue was a product of the 70s. It was accidentally invented by Dr. Harry Wesley Cooper while he was trying to make gun sights. Since then, Krazy Glue has become an American household name and a wonderful DIY super glue assistant.
Maybe you don’t need glue as strong as an animal or can resist harsh weather. For a softer option, there’s the Home and Office Brush-On Glue from Krazy Glue.
The glue is ideal for basic DIY repairs and other simple gluing tasks. Its no-clog bottle makes it easy to use. Strength and versatility are the main features and can handle DIY plastic, paper, and wood projects. The brush-on applicator also makes it easy to use.
How To Get Krazy Glue Off Skin
If you get Krazy Glue on your skin, the best way to remove it is with acetone. You can also use rubbing alcohol as it works as a solvent on your skin.
How Long Does Krazy Glue Take To Dry?
It takes two to six minutes for Krazy glue to dry. If you’re in a hurry and need it to dry faster, a hairdryer will get the job done. If you don’t have a hairdryer, then a good backup would be baking soda. Yes, that’s right, baking soda will help Krazy glue dry faster.
In the world of science, baking soda is known as an accelerator. All you need to do is sprinkle some baking soda over the glued area, and it will speed up the drying process.
Safety When Gluing Plastic
We’re talking about glue here—not table saws, nail guns, or hammer drills. But super glues and epoxies can be equally dangerous if not handled properly.
A few things to remember before using plastic glue:
- Wear PPE (Personal Protective Equipment) such as thick gloves and goggles.
- Make sure not to inhale any of the fumes from the glue, as they can be dangerous. Wearing a mask is recommended.
- If the glue makes contact with your skin, wash it off right away using soap and warm water.
- If the glue makes contact with your eyes, flush your eyes right away and call a doctor or emergency hotline.
- Do not let children near the glue while in use and keep the glue in a place they cannot reach.
Best Glue For Plastic Frequently Asked Questions
What Kind Of Glue Is Safe For The Microwave?
The quick and safe answer is: No. As super glue is fast-bonding and can stick to most materials, you don’t want to use it with wool, cotton, or anything placed in a microwave or oven.
However, items that have been bonded with a no-run formula super glue are safe for microwave use.
How To Repair Plastic Eyeglass Frames With Super Glue?
When you break your eyeglass frames, you need a DIY solution so you can use your glasses. You can fix your frames with superglue, but make sure you use the right kind of glue. The best super glue is one that can be sanded and dries clear. You don’t want the glue to affect your glasses and vision.
Epoxy resin is the best super glue for eyeglass frame repair. It’s stronger than super glue adhesives. UV activated super glue is another top choice. It works like normal superglue. The difference is UV superglue works after exposure to ultraviolet light.
Whatever you choose, super glue offers temporary but not permanent relief.
