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 adhesives are solutions of rubber and synthetic resin in a solvent.
Manufacturers use reclaimed rubber as raw material. They give a strong elastic connection, immune to the effects of oils, water, vibration, shock loads.
The undeniable advantage of rubber based adhesive and solvent is its ease of use.
It is necessary to apply the agent, wait for it to dry for a while, and connect the parts with minimal pressure. Contact adhesives do not even need to be pressed. Can be cured both at normal temperature and when heated.
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.
Ready-made formulations in liquid form are supplied to the production. But some types of glue still need to be diluted to the required concentration with a solvent.
The strength of the resulting joint depends on the quality of the rubber and resin additives, as well as the preparation of the surfaces before gluing, the characteristics of the material, and the accuracy of the gluing technology.
Since rubber-based adhesive for PVC and other materials contains acetone, gasoline, benzene and dichloroethane, it is very toxic and flammable, so it is important to follow safety rules when using them.
Universal rubber adhesive has not yet been invented, therefore, depending on the purpose, they are divided into the following categories:
Natural Rubber Adhesive Natural Rubber Rubber Adhesives are high viscosity solutions of milky white, light brown or translucent color.
Offered by the buyer in the form of a two-component vulcanizing adhesive.
Cured by vulcanization or evaporation of water, solvent.
If it is necessary to work with porous materials, they resort to wet gluing technology with further removal of the solvent. For non-porous materials, contact bonding under slight short-term pressure is suitable.
The resulting compound is highly resistant to water and microorganisms, but low to solvents and oils. Also, according to a number of properties, they lose to synthetic-based products, namely, in the strength of the connection, in the degree of toxicity, and also in the need to use various additives.
Adhesives are used in cases where there are no high demands on the connection, for example, they glue paper, fasten the soles of shoes, are used in furniture production, fasten carpets, felt, packaging materials.
Compounds based on natural rubber have a very high elasticity, high stickiness. Adhesive-applied surfaces can be bonded even after several weeks with slight pressure.
Synthetic rubber products are indispensable for all types of work - both indoors and outdoors. With their help, wood is fastened to metal, finishing panels are attached to concrete, plaster, plywood, door frames, expanded clay slabs, plywood floors, carpet and felt coverings are glued.
Apply to a dry, clean surface using a mortar gun in a criss-cross or zigzag pattern.
Compounds based on chloroprene rubbers are popular, where gasoline, ethyl acetate, toluene, benzene are used as a solvent, as well as special additives - clay, silicon dioxide, calcium silicate.
High bond strength is achieved by vulcanizing the rubber, ie by heating or by adding a catalyst.
Used in production for gluing rubber rubber and glass, concrete, wood using a cold method, and in everyday life for laying linoleum on concrete or wood.
It is also used for shoe repair - fastening fabric and leather materials. In the furniture industry, it is used for gluing latex and wood, foam layers, fastening plastic and fabric to wood.
90,000 gluing on the basis of rubber (rubber adhesives)adhesives based on rubber
are obtained from natural (NK) and synthetic rubber of almost all types:
Natural, divinating, isoprene, chloroprene, divininitrile, buttles, butyle -bouteles, butticolin, and acrytine chloride, butter , Silicone, Urethane, Fluororubber, Epichlorohydrogenated, Fluorosiloxane, Propylene oxide, Polysulfide, Ethylene-propylene.
However, adhesives in which rubbers are introduced to increase the elasticity and viscosity of the compositions, as well as stabilizers, for example, dispersion adhesives, do not belong to this group of adhesives. Rubber-based adhesives are characterized by high elastic characteristics after curing, as a result of which they find widely used for bonding elastic materials.
Most often, rubber adhesives are CLASSIFIED BY THE TYPE OF RUBBER used in their composition. For example, an adhesive based on nitrile rubber is called "nitrile rubber adhesive".
Sometimes they are classified into GENERAL and SPECIAL PURPOSE adhesives.
DEPENDING ON THE COMPOSITION, adhesives are divided into two groups.
First group - NON-VULCANIZING RUBBER ADHESIVES. Bonding with such adhesives is achieved by removing the solvent. Basically, these are single-pack systems based on natural rubber.
The second group is VULCANIZING ADHESIVES (sometimes called self-vulcanizing). These are two-pack or one-pack formulations.
When bonding with two-pack compounds, their vulcanization begins after mixing the components, one of which is a rubber solution with some additives, the other is a vulcanizing system. Mix the components immediately before applying the adhesive. Their curing (the term vulcanization is often used in relation to rubber adhesives) can take place both at room temperature and at elevated temperatures.
One-pack rubber adhesives can be cured (vulcanized) both at elevated and at room temperature.
Hot-vulcanizing adhesives are liquid systems (solutions or dispersions) with a viscosity of 0.05-20 Pa*s. They are used both for bonding unvulcanized rubbers with subsequent vulcanization, and for bonding vulcanized rubbers. Hot vulcanizing adhesives typically provide adhesive joints with higher strength and stable performance than cold vulcanizing adhesives. Adhesive joints made with such adhesives are highly elastic, their strength is at the level of rubber strength. COLD VULCANIZATION adhesives are cured in a thin layer. Some types of adhesives, such as those based on silicone rubbers, cure by reacting the curing agent with moisture in the air.
SOLVENTS. In addition to rubbers, most rubber adhesives contain a solvent. From the point of view of technological and operational properties, the best solvents for rubber adhesives are aromatic and chlorine-containing compounds, however, due to toxicity, their use is limited.
The most widely used solvents in general purpose adhesives are nefras (predominantly grade C with a boiling point of 80-120°C and a minimum content of aromatic hydrocarbons), ethyl acetate or mixtures thereof.
The most widely used mixtures of ethyl acetate with nefras with a ratio of 2:1 or 1:1 (wt.). To improve the solubility of rubbers, additional toluene or methyl ethyl ketone can be introduced into the composition of these mixtures, ensuring an equal (by weight) content of solvents in such ternary systems. The use of solvent mixtures makes it possible to control the technological properties and ensure the stability of adhesives during their storage and use.
Aliphatic, aromatic and chlorine-containing hydrocarbons and alcohols are also used as solvents for adhesives intended for bonding rubbers for special purposes.
In order to reduce the fire hazard and toxicity of adhesives, they are prepared on the basis of latexes (based on NK, polychloropreon latexes, etc.
), the dispersion medium in which is water. Aqueous dispersion adhesives have less tack than similar adhesives with organic solvents.
To increase the strength of adhesive joints, the COMPOSITION of rubber adhesives includes phenol-, urea-, melamine-, alkylphenol-formaldehyde, epoxy, coumarone-indene and adkyd resins, rosin, low molecular weight polystyrene. To maintain high elasticity of adhesives, they are introduced in small amounts of 0.2-10% (wt.).
VULCANIZING AGENTS are selected according to the type of rubber used in the adhesive. For general purpose adhesives, sulfur (0.1-0.3% (wt.)) is most often used in combination with accelerators, metal oxides, combinations of metals with amine-containing compounds, thiourea. Peroxides are widely used in special-purpose adhesives, and the resins used to modify the adhesive are simultaneously vulcanizing agents. In cold vulcanizing adhesives, polyisocyanates, epoxy compounds and amines are used for this purpose. For the vulcanization of organosilicon rubbers, organic peroxides and compounds of a number of oximes are used, it is possible to use tetraethoxy and tetrabutoxysilanes, 2-methoxyethoxysilane and similar products in combination with a catalyst.
PLASTICIZERS for rubber adhesives are mineral oils, lanolin, phthalates, sebacates, esters of aromatic carboxylic acids.
STABILIZERS in rubber adhesives are mainly used to prevent gel formation. For this purpose, diethylamine, ethanol and some others are used.
Metal oxides, carbon black, white soot, aerosil are used as FILLERS. The carbon black is simultaneously used to control the quality of the adhesive mixing.
OPERATING TEMPERATURE RANGE depends on the nature of the rubber in the adhesive:
| Rubber type | Operating temperature, °С |
| Natural | -50…+100 |
| Chloroprene | -50…+70 *For cold vulcanizing adhesives; -50…+100-150 **For hot vulcanizing adhesives |
| Butyl rubber | -50…+200 |
| Nitrile Butadiene | -60…+200 |
| Urethane | -70…+120 |
| Flour rubber | up to 250 |
| Silicone | -110…+300 |
The strength of adhesive bonds depends on the nature of the rubber used in the adhesive and the curing system.
As a rule, the strength of adhesive bonds when bonding rubbers is higher than the strength of the rubbers themselves.
