While some epoxies form an incredibly strong bond in only five minutes, others can require more than two hours of clamping, 12 hours of drying time, and one to two days until they are fully cured. Epoxies are best for metal, ceramics, rubber, wood, and certain plastics. When the two are pushed out of the tubes onto a surface and combine, they create a very strong, durable, and water-resistant adhesive. One tube is filled with a resin, the other with a hardener. EpoxyĮpoxy normally comes in two tubes with separate or connected plungers, depending on the brand. As the name implies, this adhesive is commonly used for joining plastic components while building models it’s also used to connect ABS pipe together and in plumbing with PVC pipe. It cannot be used with metal, wood, ceramic, stone, or concrete. This method of joining materials makes model cement only effective on plastic. Model cement relies on solvents like butanone, toluene, or dichloromethane (DCM) to melt plastic on application and a filler, such as polystyrene, to then weld the plastics together. Also, keep in mind that cyanoacrylate can discolor or degrade acrylics, so it wouldn’t be ideal for gluing plexiglass windows for example Model Cement The one exception is hard, smooth plastics for optimum results in projects like automotive body repairs, use sandpaper to scuff smooth plastic before applying Super Glue. Since almost any surface has at least some moisture on it from humidity in the air, Super Glue can form a strong bond between virtually all surfaces. This essentially means that Super Glue only requires water to bond to a substance. While some adhesives rely on evaporation to form a bond between two objects, cyanoacrylate (commonly known as Super Glue) uses anionic polymerization to form a chemical bond when it comes in contact with hydroxyl ions in water. Strong glues designed for plastic come in several different types, including cyanoacrylate (Super Glue), model cement, epoxy, and multi-purpose.

So don’t get stuck using the wrong product. Most DIYers maintain a collection of adhesives to get the job done right the first time. A glue that works well bonding plastic to plastic may be a poor choice to adhere plastic to metal or wood. Trickier still, gluing plastic depends largely on the target material. Even Super Glue-possibly your default option for just about anything-has its limits, as cyanoacrylate, which is its active ingredient, doesn’t adhere well to smooth surfaces. Wood glue, for example, is great for carpentry but won’t be effective on metal. Adhesives are chemically designed to work with certain materials. One formula definitely does not fit all when it comes to glues for your DIY projects.
