    J-B Weld is renowned for its excellent adhesives, which is why some of their epoxies had to make this list. The 50139 Plastic Bonder is a two-part urethane adhesive that provides long-lasting bonds to plastics. It is also an effective gap filler.

    Since it is a two-part epoxy, this product comes with a resin and hardener that you have to mix to create the bonding solution. While it is not a difficult feat to accomplish, you must be keen during mixing, as the mixing ratio must be 1:1 to create an effective solution.

    The 50139 allows you a generous 15 minutes to position your workpieces before it starts drying, thus ensuring a tidy finish. However, it can take up to 30 hours for it to cure completely. Nonetheless, once it does, it forms an unbreakable bond with a tensile strength of 3,770 PSI.

    Moreover, it allows for multiple uses. Once you mix the solvents, simply wipe the syringe using a dry cloth and return it to its cap.

    Buyer’s Guide

    Epoxy adhesives for bonding plastic are excellent solutions for many reasons. For starters, while being easy to use and fast to apply, they form bonds that are tremendously strong, with some epoxies achieving tensile strengths of up to 5,000 PSI.

    Additionally, epoxies tend to form bonds that are flexible and weather resistant, thus making them a great seam-sealing solution.

    And then, epoxies are incredibly cheap products. However, it is not every epoxy that will be right for your needs.

    The following are some of the things to consider when comparing different epoxies for plastic. These factors will allow you to find the best product.

    Tensile Strength

    Tensile strength refers to how strong the resulting bond is. Naturally, your ideal product should have a higher tensile strength as it ensures that your bonds are firm and long-lasting. Tensile strength is usually measured in pounds per square inch (PSI).

    As a rule of thumb, only consider epoxy products that clearly indicate the tensile strength of their adhesive bonds, as they leave no room for doubt.

    Resilience

    Even though an epoxy might create bonds with high tensile strengths, it does not necessarily mean that those bonds can withstand extreme conditions. If you are looking to use the adhesive on plastics that are being exposed to such conditions routinely, it is important to ensure that the epoxy is durable.

    Manufacturers will often indicate the extremes that their products are capable of withstanding.

    Flexibility

    Plastic fixtures require some degree of flexibility between joints for longevity. This is because a rigid or stiff connection breaks easily when the plastic pieces shake or bend. Despite forming firm bonds, the best epoxies for plastics are designed to allow their bonds to retain a small degree of flexibility so that they can absorb shock better.

    Container Size

    The size of a container is especially important when it comes to epoxy products that only allow for one time use. If you only need to fix a small area, it would be counterintuitive to buy a large-sized one-time use epoxy, as the rest of the product will go to waste.

    Conversely, you could end up with a bad finish if you run out of adhesive while in the middle of a job. Therefore, ensure that you estimate the amount of adhesive your project needs before you set out to buy one.

    Brand

    While there are many great, less known products, you can never go wrong with a reputable brand name. Some of the brands with a reputation for creating high-quality epoxy include J-B Weld, Gorilla Glue, and Loctite.

    Price

    The price of these products can differ significantly depending on their properties. Stronger glues are usually more expensive. Nonetheless, not all your needs will require an epoxy with industrial strength.

    Conclusion

    While there are numerous types of effective glues out there, few are plastic-friendly. Therefore, if you are looking to create firm, safe, and long-lasting bonds between your plastic wares, you must use an adhesive that has been designed for that purpose.

    Epoxy adhesives are some of the best glues to use on plastics. This is because they enhance the structural integrity of the plastic while retaining a fair amount of flexibility within the bond.

    However, even among epoxies, there are some products that will suit your needs better than others. This is why it is crucial to do your homework well. In the meanwhile, we recommend that you check out the Gorilla 2-Part Epoxy. It is a versatile, strong, and reliable product from a renowned brand. And it comes at a reasonable price.

    The PC Products 70147 epoxy is remarkably resilient and great for bonds on detailed projects. It’s easy to use and doesn’t make a mess, which is why we’ve chosen it our pick for best value.

    Now that you’ve read our reviews, you should be ready to buy the best epoxy for plastics that meets your needs.
