Plastic breaking apart is a very common thing. Nevertheless, finding the right adhesive for repairing or bonding plastics can be challenging. You might always wonder, “What glue sticks plastic to plastic.”
That’s because not all types are suitable for bonding plastic to plastic. While some create a super strong bond, the others just don’t work on the plastic surfaces.
But then again, you don’t have to be disheartened. I have a list of all the glue that sticks plastic to plastic, so you don’t have to waste time searching for them.

What Glue Sticks Plastic to Plastic?
Considering the convenience of my readers, I have discussed all the glue that will stick plastic to plastic. Just go through them to find the right type for you.
#1. Epoxy Adhesive
There are several reasons epoxy adhesives are one of the best choices to adhere plastic to plastic. And the top of them being the strength of it.
Even though the surface of the plastic items is super smooth, this adhesive still adheres to them strongly because of its chemical composition.
The combination of resin and hardener augments the structural strength of the plastic and holds the surfaces together, even when they are not porous.
Advantages and Limitations of Epoxy Adhesive
Advantages of Epoxy Adhesive
- Epoxy adhesives provide a strong and durable bond between plastic surfaces for longevity.
- These adhesives are often heat and chemical-resistant and, therefore, don’t mess up the plastic-to-plastic bond anytime soon.
- Because they have excellent gap-filling capabilities, epoxy adhesives can also fill the gap between plastic surfaces precisely for an even stronger bond.
Limitations of Epoxy Adhesive
- These adhesives take about 24 hours to cure properly on plastic surfaces.
- Even though they are an excellent choice for plastics, you might need to prepare the surface for the strongest bond.
#2. Acrylic Adhesive
Just like epoxy, acrylic adhesives have their own set of features, which make them the right choice for plastic-to-plastic bonding.
Because of their construction, low viscosity, and incredible versatility and strength, these adhesives not only form a bond but “cement” the plastic surfaces together.
It doesn’t matter if you are using them on PVC, ABS, HIPS, or any other type of plastic; this glue will always hold them together for a long period.
Use Cases and Strengths of Acrylic Adhesive in Plastic-to-Plastic Bonding
Strengths of Acrylic Adhesive
- It doesn’t matter what type of plastic surface you are using this adhesive on; an acrylic glue provides strong bonding capabilities and sticks the surfaces together for a long time.
- Acrylic adhesives are transparent. Therefore, they won’t show up after the complete curing process on the plastic.
- These adhesives are UV resistant. Therefore, even if you put the plastic items outside, the bond won’t come off anytime soon.
Use Cases of Acrylic Adhesive
- DIY crafts and projects
- Household repairs
- Constructions
- Electronics
- Pipes and others
Advantages and Limitations of Acrylic Adhesive
Advantages
- Heat, chemical, and UV resistant
- Cures super fast
Limitations
- Requires surface preparation

#3. MMA Glue
Epoxy adhesive and MM Glue work similarly on plastic surfaces. Because this glue has excellent bond strength, adheres to even the smoothest of surfaces, and offers longevity, it is an excellent choice to stick plastic to plastic effectively.
How MMA Glue Adheres to Plastic Surfaces
To use MM glue to stick plastic to plastic, prepare the plastic surface first. Then, apply the glue in the right amount and smear it perfectly so that the bond is strong and durable.
Stick the surfaces together and wait for a few minutes before they attach to one another. Let the bond cure for the specified time.
Safety Precautions and Applications of MMA Glue
Safety Precautions
- Make sure to work in a properly ventilated area to avoid inhalation hazards.
- Be careful not to smear the adhesive on the fingers.
Applications
- Home improvements and household repairs
- General purpose
- Automotive industry
- Constructions and buildings.
#4. UHU Glue
UHU glues are the right pick for sticking plastic to plastic because they are not only super strong and easily glued together, but this glue is also transparent.
Its transparent nature makes sure that the glue doesn’t show on the surface and doesn’t give up the fact that the surfaces are glued together.
Another thing that makes this adhesive perfect for plastic surfaces is its formulation. Made with a polyvinyl acetate material, it can form a strong bond, which won’t come off anytime soon.
Varieties and Their Effectiveness on Plastics
Varieties
- UHU Glue Sticks
- UHU Super Glue
- UHU All Purpose Adhesive
- UHU Epoxy Quick Set
Effectiveness
- Strong and durable
- Doesn’t come off anytime soon
- Easy, fuss-free to apply
Best Practices for Application
- Perfect for sticking plastic to plastic
- Can join a whole lot of other materials like wood, glass, ceramics, and others.
- A Perfect pick for crafts and household repair projects.
#5. Cyanoacrylate Adhesive
Cyanoacrylate adhesive or super glue, however you call it, is the perfect pick for sticking plastic to plastic. This is because this adhesive works perfectly fine even on smooth surfaces and creates a super strong bond.
Besides creating a strong bond, a Cyanoacrylate adhesive is also known for creating a quick adhesion. Because it is specially made, this glue cures faster than others and joins the plastic surface in no time.
Benefits of Cyanoacrylate Adhesive
- Creates a hard, strong, and durable bond.
- Ensures a clear finish
- Doesn’t require excessive surface preparation
- Heat, chemical, and impact resistant
Where To Use Cyanoacrylate Adhesive
- Craft and hobbies
- Household repairs
- Jewelry repair and other DIYs
- Automotive Repair
