At some point in time, there may be a need to remedy a small leak or a burst to your tire tubes. Therefore, adhesives made up of rubber cement or vulcanizing fluids are common products used to patch tire tubes and make them useful again.
Although they may serve the same purpose, they are different in composition and how they work. In this article, we are going to walk you through the difference between rubber cement and vulcanizing fluid and why it is not advisable to use rubber cement adhesive on bike tubes.
Rubber cement is sometimes sold in stationery stores. It is an adhesive which is mostly made from an elastic polymer, particularly latex, and mixed with solvents such as hexane, toluene, acetone, or heptane. More often than not, the mixture is not strong enough to perform an effective patch work on your tires.
To add to the confusion, some bike repair kits come with a “rubber cement” that is actually self-vulcanizing fluid. These are really the “vulcanizing fluid” products that you should be using.
What is Vulcanizing Fluid?
Vulcanizing fluid is another adhesive that is used in making cross-links in materials made of rubbers. They are fast-drying adhesives that can be used with or without heat.
How do Rubber Cement and Vulcanizing Fluid Work?
Rubber cement and vulcanizing fluid are adhesives that are used in patching up rubber components. They are both made up of elastic polymers like Gum Arabic, which, when dissolved in volatile solvents like benzene or acetone, give them the property of hardening and cross-linking broken rubber parts, upon the evaporation of the volatile solvent.
Tire tubes are made of vulcanized rubber, which is precisely the components these adhesives have to work with to produce a significant effect. After the application of the adhesive, the tire tube gets reformed with bonds to the polymer in the glue. Upon evaporation of the volatile solvents, the inner side of the glue must have wholly bonded with the tire tube, leaving you with a choice of peeling off the outside remnant or leaving it to wear off.
Most bike tubes contain rubber components that are not very strong. Rubber cement is not particularly effective at patching tire tubes, and may even cause rubber components to break down, thereby damaging them for further usage.
The Best Solution is a Patch Kit
The patch kit is otherwise known as the service/ repair kit. These are a set of tools and spare parts that are used in the repair of tire tubes. They can be kept in the vehicle and moved around to ensure an on-the-spot repair.
The components of the patch kit vary from manufacturer to manufacturer. A typical patch tool contains tire levers, sandpapers to make the affected area clean, a vulcanizing fluid, a wax crayon to mark the affected area, and a metal grater.

Rubber adhesive is nothing more than natural rubber dissolved in a solvent. This type of adhesive is highly elastic after curing, which is why it is used when bonding elastic materials.
Rubber is a natural elastomer, i.e. a substance that is able to stretch several times its original size and then fully restore its original shape.
The properties of the rubber adhesive depend on the type of natural rubber and the pre-treatment method. Rolled rubber adhesive has higher concentration and adhesive power and lower viscosity than unrolled rubber adhesive. To reduce the viscosity, up to 1% ethyl alcohol is sometimes added to the adhesive. To increase the stickiness of the adhesive film, rosin is added in some cases (up to 10% of the mass of the adhesive).
Adhesives are classified into two categories: curable and non-curable. The first group is adhesives containing not only rubber, but also vulcanizing agents. During vulcanization at a temperature of 150C, a stable insoluble adhesive bond is formed. To prevent premature vulcanization, two components are used, the accelerator is introduced into the first, and the vulcanizing agents into the second. The components are mixed immediately before gluing.
The second group includes solutions of cyclized and natural rubbers, which, after evaporation of the solvent, form elastic, but not very strong compounds.
To date, the range of application of the adhesive is very wide: from the automotive industry (where rubber adhesive is used to seal threaded joints) to medicine (where phenol-formaldehyde composition is used).
Ideal for shoe repairs as it adheres perfectly to plastics, rubber and textiles. At the same time, it withstands constant deformations characteristic of shoes.
A rubber-based adhesive is also used as a protective coating for complex parts with a high coefficient of friction.
Precautions
Before using rubber adhesive, you must read the instructions, as well as take precautions, because the solvent that is the basis of this adhesive is very toxic.
If adhesive gets into your eyes or mouth, immediately wash the affected area with soap and water and seek medical attention.
Torque for rubber Product features / purpose :
• Designed for bonding all types of hard and foam rubber.
• Ideal for bonding rubber to a variety of materials: concrete, rigid PVC, metal, wood, cardboard and more.
• Provides high strength, elasticity, reliability, durability and water resistance of the adhesive bond
• Frost resistant.
• Heat resistant (from minus 30°C to plus 100ºC).
This adhesive is extremely toxic and flammable and for these reasons should only be handled outdoors or in a very well ventilated area and away from open flames.
