Than and how to glue rubber: choosing the best rubber composition and gluing instructions

Rubber is a material that can be used for many different things, from industrial components to household items. However, because of its peculiar qualities, bonding rubber can be a little challenging. To ensure a strong, long-lasting bond, it’s crucial to select the appropriate adhesive and adhere to the recommended gluing procedure when repairing rubber hoses, gaskets, or custom rubber items.

Rubber doesn’t work well with all adhesives. Some might not stick well, and others might eventually make the rubber deteriorate. Consequently, it’s essential to use a glue made especially for rubber materials. These adhesives are designed to work with rubber’s elasticity and toughness, guaranteeing a strong and long-lasting bond.

We will walk you through the process of gluing rubber in this article. We’ll start by discussing the various kinds of rubber adhesives that are available, along with their benefits and drawbacks. For optimal results, we’ll then go over how to prepare the rubber surfaces and apply the adhesive step-by-step.

You can complete projects and repairs of a professional caliber by knowing the characteristics of rubber and applying the proper adhesive techniques. Let’s get started and learn how to properly glue rubber so that your products remain firmly bonded and functional.

Where it is used

Rubber can be fixed using rubber tools:

  • shoes with rubber sole;
  • tires;
  • cycles of bicycles;
  • seals and other rubber elements;
  • balls, tents, inflatable or water mattresses;
  • Swimming costumes, fishing and special coins;
  • boats, kayaks and other crafts and rubber.


Rubber is the primary component.

It may be liquid or viscous, depending on the consistency. Additionally, there are two-component means. However, the fundamental component still has dissolved rubber, regardless of the release method. However, the solvents may differ:

  1. Chlorine -containing substances, arenas. Rather toxic substances, so there are few of them in the composition of glue.
  2. Latex with water. Has low toxicity, low degree of fire, but does not adhere to the basis.
  3. Ethyl acetate with nephras. The components have oil products.
  4. Resin with polystyrene. The component makes the seam more durable, but with a large concentration, its elasticity is lost.
  5. Ftalates, lanolins – plasticizers. In addition to them, there are complex esters like mineral oils or carboxylic acids in.
  6. Sulfur, metals oxides, amines. These components are according to the quality of rubber, responsible for the process of vulcanization.
  7. Dietylamine, ethanol – stabilizers. Do not allow the transition of glue to a gel -like state.

For a strong, long-lasting bond when gluing rubber, the right adhesive must be chosen and the right gluing techniques must be followed. The best rubber adhesives are silicone-based, polyurethane, and cyanoacrylate-based adhesives; each is appropriate for a particular type of rubber and application. It is essential to prepare the rubber surfaces by cleaning and roughening them, evenly applying the adhesive, and allowing enough time for curing if you want the best results. This guide will give you step-by-step instructions for successfully gluing rubber and assist you in understanding the advantages of each type of adhesive.

Properties and characteristics

The primary distinction between rubber part glue and other types of glue is the flexible seam’s ability to maintain its plastic structure while in use.

Because of its extreme strength, rubber can be glued to metal, plastic, skin, and other materials in addition to other rubbers. The rubber-based adhesive composition takes on the properties of rubber after it has hardened.

The following features should be present in a rubber adhesive:

  • moisture resistance;
  • resistance to t = -40 …+100 ° C;
  • strength;
  • resistance to aggressive environments;
  • the ability to fill in any coating defects;
  • elasticity;
  • lack of toxic smell;
  • transparency;
  • Seam protection from rusting, decay and so on.

Types of glue for rubber

It is not advised to use universal compounds for adhesion; instead, use specialized adhesive.

The consistency of glue can vary depending on the primary component.

  • From natural rubber. In such compositions, the vulcanizing component is sulfur. They are glued by leather, paper, fabric surfaces and rubber among themselves.
  • From chloroprene. Suitable for gluing rubber to wood, glass, plastic, metallic bases.
  • From butadien-nitrile rubber. The vulcanizer is sulfur with tiuramas, providing the composition of increased water resistance.
  • From silicon rubber. The hardener is tetrabotoxilan. Glue the same in texture rubber.
  • From synthetic butadien rubber. Gluing poorly, is used in industry.
  • From a solution of uretany rubber. Used in the shoe industry.
  • From innovative components. It is not used in everyday life, it is made for industrial purposes.

Natural rubber is not very resistant to heat or outside influences. Furthermore, its application scope is too narrow, which served as the catalyst for the development of adhesives made of synthetic rubber using cutting-edge technologies.

There are two types of rubber mixtures based on dry residue:

There is also liquid rubber. It looks like a polyurethane base with a transparent glue-paste appearance. Sealants made of selfless rubber are frequently used. has a flexible texture, is resistant to wear, is not affected by temperature changes, and has good protective qualities.

Rubber glue is categorized based on its composition as well as the characteristics of the adhesive seam that forms once it has hardened.

  1. Moisture resistant. They glue shoes, leatherette, repairs rubber boat, that is, any objects of rubber that are under the regular influence of water.
  2. High -strength. Such a composition forms a reliable seam that can withstand a strong effect. Used in the construction industry, in the repair of automobile parts. The product glues the elements so firmly that it will be very difficult to redo the work, so it is worth performing all the actions neatly.
  3. Quickly dry. Helps to quickly glue, saves time. It is better to use when working with overall details.
  4. Elastic. Cloth parts subject to dynamic loads in which the position of the seam during operation can vary in any direction.
  5. Oil -resistant. Oil and gas-resistant surfaces are fastened.

There are two kinds of adhesives, depending on how they cure.

  • Compounds without vulcanization. Hard after evaporating the solvent.
  • Self -ovalkanizing mixtures freezing under the influence of moisture in the atmosphere. There are one and two-furnace.

What to consider when choosing

  • The thickness and dimensions of the rubber base, resistance to abrasion.
  • The pasted product should remain plastic or hard.
  • Humidity and t ° C of air in which the glued item will be glued, and then operated.
  • Appearance of an object in need of repair.
  • Composition, characteristics of the mixture and the degree of chemical aggressiveness.

The best brands for gluing rubber

Glue 88 (s, n)

Bakelite and rubber-based cleansers are made. Rubber to rubber can only be glued with 88-C and 88-N brands of rubber. The first glue was used in daily life, in the shoe industry, in cars, and in construction.
