The following list details types of rubber and their uses. Type of Rubberīefore selecting the best glue for rubber to rubber or rubber to other substrates, it’s important to identify the type of rubber to be glued. From there, shoppers can determine the best type of glue, keeping in mind various factors such as weather resistance, flexibility, set time, cure time, and more. When choosing an adhesive product for rubber, the first step is to identify the type of rubber to be glued. What to Consider When Choosing Glue for Rubber If an adhesive bond does not hold, the user can apply a primer to increase the surface friction before applying the silicone adhesive. Additionally, they resist damage from high temperatures and exposure to chemicals and water. This type of glue creates bonds that are flexible (not rigid) after curing. The best glue for silicone rubber is a silicone-based adhesive. Additionally, manufacturers use silicone rubber in the production of gaskets, O-rings, medical devices, and prosthetics. For this reason, it’s used in making ovenware and cookware. Silicone rubber is exceptionally resistant to high heat. Therefore, they demonstrate a longer shelf life, and users may count on their efficacy after storing for extended periods. Since they are stored separately, two-part adhesives are more stable than the premixed types. The user purchases these adhesives in two separate parts and mixes them immediately before applying the adhesive. Two-part structural acrylics can work well for these difficult gluing jobs.įor activation to occur, two-part acrylic glues require mixing. With slippery, smooth, and nonporous surfaces, it may be difficult for glues to form bonds on these materials. These include polyethylene, polypropylene, polytetrafluoroethylene (PTFE), and ethylene propylene diene monomer (EPDM) rubbers. Two-Part Acrylic GlueĬertain rubber substrates are known to pose problems when users try to adhere them. Therefore, it’s useful for outdoor applications as well as indoor repairs around the home. Additionally, it’s useful for filling gaps. With the double syringe, these steps are neat and simplified for the user.Įpoxy resin forms a waterproof and weatherproof bond. A double syringe system is often used for storing, mixing, and applying epoxy resin. Users mix the two parts together in a 1:1 ratio immediately before applying the adhesive to a substrate.įor storage, the resin and the hardener are housed in two separate containers. Epoxy Resin GlueĪn epoxy resin glue consists of two parts: a resin and a hardener. Allow 24 hours for most super glue products to fully cure. Upon curing, cyanoacrylate transforms into a plastic state. Therefore, it’s important to work fast when using super glue. While the quick setup time facilitates swift completion of assembly and repair jobs, it limits a user’s opportunities for adjusting or repositioning surfaces. In only a few minutes, cyanoacrylate begins to set up, forming a strong and rigid bond. This ingredient is an acrylic monomer that requires moisture for curing. Its primary adhesive ingredient is cyanoacrylate. Super glue is an acrylic resin and a viable choice as an all-purpose glue for rubber. These include epoxy resin and structural adhesive glues. Alternatively, some rubber adhesion projects require two-part adhesives that require mixing for activation. These include one-part glues such as super glue that’s also called cyanoacrylate adhesive (CA) and silicone-based glue. Manufacturers offer several types of glue that work well with specific types of rubber. BEST SILICONE ADHESIVE: J-B Weld Clear Silicone Sealant & Adhesive.BEST PLASTIC TO RUBBER: 3M Scotch-Weld Plastic & Rubber Instant Adhesive PR40.BEST BANG FOR THE BUCK: Loctite Super Glue Ultra Gel Control.Read on to discover products that offer some of the best glue for rubber adhesion to meet the challenges of many DIY projects. The difficulty of bonding two smooth and nonporous substrates may present an additional problem. For other jobs, the flexibility or elasticity of the bond is important. In some cases, weather resistance and waterproofing are desired. The best options provide a strong, durable bond that’s permanent when it’s fully cured. Manufacturers offer a range of glue types for specific types of rubber, so choosing the best adhesive for rubber can be challenging. When it comes to gluing rubber to rubber or a variety of diverse substrates, the project’s success depends on selecting the optimal adhesive for the job.
