Epoxy for Plastic Buying Guide
Above we have mentioned the top 10 best epoxy for plastic products, along with tips to safely use it. Now you may or may not know which epoxy will be more suitable for your need.
So for your ease, we will be discussing a list of factors that you should take into account when buying epoxy for plastic. This way, you will know exactly which one to buy.
Picking out the perfect applicator for your usage can be tiresome and confusing. You have different options to choose from. To make this easy for you, if you want easy dispense, you can opt for putties or tubes.
However, if you want equal dispense then you can opt for syringe containers. And if you want to use your epoxy more than once then we suggest getting one with a cap to cover it. That way you can reuse it whenever you need again.
A crucial factor to take into account is the surface on which you will be applying the epoxy. In our article we have mentioned the materials that are compatible with each plastic epoxy.
Since we reviewed products that are mainly meant for plastic, you need to make sure that the epoxy you are getting is compatible to plastic.
Time to Dry
Depending on how much time you have to spare, choose from the different dry time options. Most epoxies have a dry time ranging from and hour to 5 hours or even 24 hours.
We live in an age where time is money, we would recommend opting for the best epoxy glue for plastic with a quicker drying time.
You have to decide if you want to reuse the epoxy several times and repair a lot of things. If so, we suggest you go for one that has more than 0.87 Oz. in amount.
This factor is basically the plastic epoxy’s strength and durability. Whether you want a tough one or a less brittle one is your choice.
Above we have mentioned the strengths of the plastic epoxies, so you can choose depending on your requirements.
Temperature plays a big role in preventing the object from collapsing. Some epoxies have higher temperature limits, while others have lower.
If you want to use the object you are fixing for outdoor or indoor purposes then it should have a temperature limit of -50oF to 120oF. But if it’s going to sit in the freezer then it should have a limit of at least 212oF.
Resistance to water, chemicals, sunlight, fire and other factors can determine how versatile as well as durable the finish of an epoxy would be. Getting a water-proof epoxy for plastic will ensure that the adhesive does not dissolve with contact with water.

Safety Tips When Working With Plastic Epoxy
Safety always comes first. It is crucial to take precautions before doing pretty much anything, as you can never be too careful. Same goes for when working with plastic epoxy.
Although the health problems that may be caused from plastic epoxy are not much, it is still necessary to be cautious about everything that could go wrong.
Here are a few safety tips to prevent any harm from happening while using epoxy-
Protective Gloves and Clothing
You must always wear protective gloves and gear before handling epoxy. If in any case you get epoxy on your skin, make sure to remove it immediately with warm water and soap.
Make sure to wear gloves made out of a material which is resistant to epoxy such as rubber or anything else. This will guarantee better safety.
Epoxies on skin can cause irritation, flaking, burning, also itchiness. Our recommendation would be to wear long sleeve clothes along with the gloves to prevent epoxy from getting onto your skin at all.
Safety glasses or goggles should be worn before handling epoxy. The goggles will protect your eyes from any splatters or toxic fumes.
If in any case you get epoxy in your eyes, immediately wash your eyes for 15 minutes, and we recommend getting medical attention as soon as possible.
Wear Respiratory Mask
Don’t breathe in epoxy vapor; a respiratory mask will prevent any fumes from getting to your face.
Irritation in the bronchial passage can be caused if you inhale the fumes from the epoxy. This can also lead to cough, nausea, headache, dizziness or even vomiting. Under any circumstances if you feel sick then go outdoors or seek any form of help.
Also, do make sure to work in a ventilated area with plenty of fresh air to prevent accumulation of dense epoxy vapors and sanding dust in the room.
When not using, keep the epoxy away from children’s reach, as well as away from heated sources and open flames. The epoxy should neither be stored in a hot place or a cold one. A cool, dark, and ventilated area is ideal for its storage.
Carefully Mix, and Apply
You should be careful when mixing the resin and hardener with the two parts of most epoxies. Start off by mixing small quantities and use it before adding more.
While applying, never use your hands even if you are wearing gloves. Always use an applicator such as wooden stick.
Safely Dispose The Epoxy
When it comes to disposing you should be careful. Do not dispose the epoxies as liquid.
You should mix a bit of leftover resin and hardener to let it cure into a solid. Afterwards, it can be disposed according to the disposal regulations.
Note: mixed epoxy should be kept in a ventilated area away from any combustible materials, as these epoxies can emit hazardous fumes, as well as even potentially start a fire.
Frequently Asked Questions
Is Epoxy for Plastic a right choice?
Epoxy is a good choice for applying on plastic as it forms a strong adhesive bond between two objects. With the ideal epoxy you can get a bit of flexibility along with resistance to various chemical.
How long does it take for the plastic epoxy to dry?
Although some of the products says that 5 minutes is all it takes to dry, but it is recommended that you wait a bit longer. You should wait at least 24 hours for it to dry completely, for maximum results.
Which is stronger, epoxy or super glue?
Both of these products are to be used for different purposes. Super glue lacks shear strength, whereas epoxy specializes in it, but both products can be used to get a stronger bond. So the bottom line is, epoxy is stronger.
Can I easily scratch off epoxy?
No you cannot easily scratch off epoxy, as it has high structural integrity which ensures that it lasts longer. Epoxy specializes in various resistance factors and scratch resistance is one of them.
So rest assured that it won’t easily come off even if your cat scratches over it with full force (maybe that was an exaggeration).
Will the durability maximize if I add more hardener?
No, adding more hardener will not increase durability. You should always stick to the measurement instructions given with the epoxy, otherwise the end product will not be as expected.
The mixing ratio is normally one-part hardener and one-part resin. So we recommend you follow that ratio.
How do I mix a plastic epoxy adhesive?
If you are getting the liquid epoxy glues, you have to mix it with the hardener using a mixer (manual or electric). The ratio, as we mentioned, should be 1 part epoxy and 1 part hardener.
If you want to avoid the whole process of mixing, get ones that come in syringes or the epoxy putty tubes.
We assume at this point you should have become an expert in epoxy resins and adhesives in general. Our informative product reviews and comprehensive guide should be enough to provide you with enough knowledge regarding epoxies.
