The best glues for plastic for most domestic tasks are super glue, epoxy, or solvent cement, but which one is ideal for you will depend on the product and how much time you have available. While liquid epoxy glue can offer a better hold, super glue is simple to use and excellent for minor repairs. You may mold epoxy putty with your hands and use it to fill in spaces. Also, bear in mind that many types of glue don’t offer polyvinyl chloride (PVC) a long-lasting grip; therefore, if you want to join PVC, you’ll need an industrial-grade solvent cement that’s specially designed for the material. In order to ensure that the glue may be used with your plastic, always verify the glue’s box. The majority of glues cannot be used with polyethylene or polypropylene plastics.
Well, in this article, we’ll be listing the best glues for plastic you should be considering for household projects. Note that this is not a sponsored post and that all the glues for plastic listed below are based on the best, top-performing ones on the industrial market.

Due to its two-step method, this superglue system may initially appear to be epoxy. However, it is actually a super glue that includes a primer to aid in the preparation of smooth plastics. It’s not necessary to combine the two formulas: Apply the plastic primer first, allow it to dry, and then add the glue. The glue hardens in a matter of seconds, but it needs 12 to 24 hours to fully cure. All polymers, including polypropylene and polyethylene, are compatible with the Plastics Bonding System. It dries clear, has a tensile strength of 290 to 2,900 PSI, and is water-resistant (but not waterproof). Moreover, it doesn’t shrink as it cures and, once it has cured, may be drilled and sanded. However, it should not be used on surfaces that come into contact with food or drink.

A very special two-part adhesive called the Infinity Bond MMA 500 bonds tough plastics like polyethylene (PE) and polypropylene (PP) better than nearly any other adhesive now on the market. Two-part adhesive Infinity Bond MMA 500 is applied using a static mixer and cartridge gun. Two static mixing nozzles are included in each cartridge for simple dispensing. The MMA 500 requires little to no surface preparation prior to application, like the majority of Methacrylate MMA adhesives. It will permanently bond with chemical adhesion even to challenging polymers and has a 4–5-minute open time.

The Gorilla Super Glue Gel is the best option when you require glue that dries clear and swiftly. You won’t have to keep the plastic items together for hours because it starts to solidify in only 10 to 45 seconds. However, the manufacturer advises waiting 24 hours for the plastic to fully cure before placing any weight on it. Its tensile strength ranges from 500 to 1,500 PSI, depending on the particular materials you’re bonding together. Moreover, the composition is thick enough to allow for simple direction control. The glue can be applied to many different surfaces, including vertical ones like walls, despite the fact that it is not water-resistant. To keep the glue fresh once you’ve opened it, the cap has an anti-clog metal pin. You can purchase it in packs of two or ten or as a single 20-gram bottle.

Particularly when using rubber substrates, the Infinity Bond Rubber and Plastic Super Glue is the ideal option for general-purpose bonding. For O-ring bonding, general repairs, and product assembly, use the Infinity Bond Rubber and Plastic Super Glue. This cyanoacrylate adhesive has the finest price/performance on the market and provides solid bindings to a variety of substrates at an unbeatable price.

Go no further than this PlasticWeld glue, which combines the resin and hardener in a single stick, to fill in any gaps, chips, or cracks. Although this glue’s tensile strength is just 600 PSI, it is safer to mold it with your hands before it dries, unlike the other choices on this list. Cut out the required amount from the putty stick, mix the putty with the other components, and then set the putty in position. PlasticWeld sets up in about 25 minutes and fully cures in about three hours.
After drying to an off-white color, it can be sanded, painted, and cut. It can be used, among other things, for vinyl surfaces or auto bumpers and trim. Once it has dried, PlasticWeld is water-resistant and suitable for contact with potable water. (However, despite reports from some users that it effectively sealed leaks, J-B Weld’s WaterWeld epoxy putty is a superior choice if you’re attaching pieces that will be immersed for extended periods of time.)

A high-performance hot melt polyurethane called the Infinity PUR MP75 bonds to a variety of surfaces. It has a longer open time of around 75 seconds, giving users plenty of time to connect larger surfaces or establish their substrates before the glue hardens. MP75 can be used to join various materials, including ceramics, cement, metal, and plastic. The length of glue produced by one cartridge is about 50 linear feet.
Compared to bulk hot melt or conventional glue sticks, the Infinity PUR MP75 offers a substantially stronger adhesion. Moreover, it is more resilient to demanding circumstances, such as applications in the interior and exterior. Good initial tack and a bind that gets stronger as it interacts with atmospheric moisture are features of Infinity PUR MP75.

Oatey’s Handy Pack A PVC-specific solvent cement is called PVC solvent cement. Solvent cement, in contrast to superglues and epoxies, melts the plastic’s surface in order to chemically connect the components. You receive a primer to pre-soften the PVC surface and cement to hold the plastic together with this two-step box. Hold the components in place after applying the primer and cement for 30 seconds, then allow it to dry. Depending on the size of the pipe and the ambient temperature, you must wait anywhere from two minutes to six hours before handling the PVC. This solvent cement is suitable for use on surfaces that will come into contact with potable water and is advised for pipes up to 3 inches in diameter.

How long does plastic epoxy last?
When resin and hardener are correctly maintained at room temperature in sealed containers to prevent contamination, epoxy shelf life can last for a long time. Polyester resins only have a six-month shelf life before they degrade into a useless jelly-like substance, according to those who have used them.
