Rubber Cement vs. Super Glue: Best Uses Compared
Rubber Cement vs. Super Glue
Best Glue for Rubber Bonding
When deciding on the best adhesive for rubber bonding, the primary contenders are rubber cement and cyanoacrylate-based adhesives, commonly known as super glue. Each adhesive has unique properties making them suitable for specific applications.
| Adhesive | Best Uses | Advantages | Disadvantages |
|---|---|---|---|
| Super Glue | Bonding various types of rubber (e.g., nitrile, butyl, polyurethane, silicone, natural rubber) | Quick curing time, strong bond, tiny application necessary (Gluegun.com) | May require primers for silicone rubber, brittle bond under stress |
| Rubber Cement | Crafts, patching small holes, bonding rubber to various materials (e.g., leather, glass, ceramic) | Flexible, waterproof, virtually unbreakable bond (Family Handyman) | Longer curing time, not suitable for high-stress applications |
For most rubber bonding projects, cyanoacrylate adhesives are an effective choice due to their fast curing time and minimal application volume. Super glue works well with many types of rubber, including nitrile, butyl, polyurethane, silicone, EPDM, and natural rubber.
However, when bonding rubber to other materials such as plastic, metal, or glass, the adhesive selection becomes more critical. In these cases, epoxy adhesives may be a better option, especially for creating robust bonds (Gluegun.com).
For crafting and smaller repair projects, rubber cement is highly effective given its flexible and waterproof bond. It is particularly useful for fixing small holes in rubber surfaces like athletic shoe soles (Family Handyman).
Factors for Successful Bonding
Securing an effective bond when working with rubber involves various factors from surface preparation to the type of adhesive used:
- Surface Preparation:
- Ensure surfaces are clean and free from grease, dust, and debris.
- Lightly sand surfaces if necessary to enhance glue adhesion.
- Adhesive Type Selection:
- Cyanoacrylate adhesives are preferred for rubber-to-rubber bonding (Gluegun.com).
- Epoxy and fast-curing silicone compounds are better for rubber-to-other-materials bonding (Gluegun.com).
- Application Techniques:
- Apply a minimal amount of adhesive; excess can weaken the bond.
- Use precision applicators for accurate glue placement.
- Bond Strength:
- Super glue achieves high bond strength quickly but can be brittle under high stress.
- Rubber cement provides a flexible, durable bond ideal for applications requiring some movement and flexibility.

By understanding these fundamental factors, one can select the most appropriate adhesive and ensure a successful and reliable bonding outcome.
Cyanoacrylate Adhesives for Rubber
Cyanoacrylate adhesives, often referred to as super glue, are widely regarded as one of the best choices for bonding rubber. They offer a host of advantages, including rapid curing times, excellent bonding strength, and versatility across various types of rubber.
Quick Curing Time
One of the standout features of cyanoacrylate adhesives is their rapid curing time. These adhesives cure in just seconds, providing a quick and efficient bonding solution. This makes them ideal for time-sensitive projects where immediate adhesion is required (Gluegun.com). A tiny drop is often sufficient for a strong bond, which also helps minimize waste.
Special Considerations
There are certain considerations to keep in mind when using cyanoacrylate adhesives for rubber bonding. While they are effective for many types of rubber, including nitrile rubber, butyl rubber, polyurethane rubber, EPDM rubber, and natural rubber, some rubbers like silicone may require the use of primers (Gluegun.com).
For rubber-to-other-material bonds, like rubber to plastic, metal, or glass, more specialized products might be needed. In particular, certain plastics may not bond well with cyanoacrylate alone, necessitating the use of specialized adhesives such as the 3Mâ„¢ PR1500 plastic to rubber adhesive (Gluegun.com).
Surface Preparation
Proper surface preparation is crucial for achieving successful adhesion. Dirty or greasy surfaces can hinder the bonding process, making thorough cleaning essential. It is recommended to use isopropanol for cleaning rubber surfaces, as it effectively removes substances like slip additives and mold release without damaging the rubber. Acetone is generally too harsh and can degrade certain types of rubber.
Steps for surface preparation:
- Clean the rubber surface with isopropanol.
- Allow the surface to dry completely before applying the adhesive.
- Follow the manufacturer’s guidelines for application to ensure optimal results.

Rubber-to-Other Materials Bonding
Bonding rubber to other materials such as plastic, metal, or glass can present unique challenges and requires careful adhesive selection for best results.
Adhesive Selection Challenges
When bonding rubber to plastic, metal, or glass, the choice of adhesive becomes crucial. Rubber’s flexibility and varying surface properties can complicate bonding with these materials. Special considerations are required since some adhesives may not be suitable for all substrates. Epoxy adhesives, for example, are highly recommended for bonding rubber to plastic, metal, or glass, as they provide a strong and durable bond.
Effective Adhesives
There are a few types of adhesives particularly effective for rubber bonding:
-
Cyanoacrylate Adhesives (Super Glue): Known for their quick curing time and strong bonds, cyanoacrylate adhesives, such as ASI RP Series Cyanoacrylate Super Glue, are among the best options for bonding rubber, especially natural rubber or EPDM (Gluegun.com). For silicon rubber, a primer might be needed before application.
-
Epoxy Adhesives: These adhesives are particularly effective for bonding rubber to plastic, metal, or glass. They provide a strong and durable bond that can withstand various environmental conditions. Fast-curing epoxy compounds are ideal for smaller projects.
-
Silicone Compounds: Fast-curing silicone compounds are also a viable option for smaller rubber bonding tasks. These adhesives form flexible and durable bonds, suitable for applications requiring some degree of elasticity.
Project Considerations
Before starting a rubber bonding project, there are several factors to take into account:
-
Material Compatibility: Ensure that the adhesive selected is compatible with both the rubber and the material it’s being bonded to.
-
Environmental Conditions: Consider the conditions the bonded surfaces will be exposed to, including temperature fluctuations, moisture, and UV exposure. Adhesives like rubber cement, for example, form nearly unbreakable and waterproof bonds.
-
Curing Time: Depending on the project, the curing time of the adhesive might be critical. While cyanoacrylate adhesives cure quickly, others like epoxy may require longer curing periods.

Application Guidelines
Proper application techniques can significantly enhance the effectiveness of rubber bonding adhesives:
- Surface Preparation: Thoroughly clean the rubber surface using a solvent degrease to remove contaminants such as slip additives and processing lubricants. Proper surface preparation is essential for a successful bond.
- Adhesive Application: Apply a small amount of the chosen adhesive (such as cyanoacrylate) to one of the surfaces. A tiny drop is usually sufficient due to the high bonding strength of cyanoacrylate adhesives.
- Bonding Process: Press the surfaces together firmly for a few seconds. Cyanoacrylate adhesives cure quickly, providing a rapid indication of bond strength.
