The combination of flexibility and strong bonding capabilities is a crucial factor to take into account when selecting an adhesive for a high-strength connection between rubber and metal. The ideal glue must be resilient enough to hold up under a variety of environmental circumstances and the varying rates of expansion of these materials. Because of their strong bond and resilience to heat, chemicals, and moisture, epoxy adhesives are frequently the best option when it comes to establishing enduring connections between rubber and metal surfaces.

Properties and types of adhesive compositions

Rubber-based compounds that dissolve in specific components are what link the rubber and the metal. The mass’s ability to maintain its elasticity after solidification enables it to firmly fix materials with heterogeneous structures. There are ways to add to the composition:

• polymer resins;
• sewing agents;

• volcanic additives;
• plasticizers.

Both domestic and commercial settings use glue. seals small gaps, fissures, and seams. usually applied as a sealant. Rubber glue has the following qualities:

• high penetrating ability;
• seam strength during prolonged operation;
• resistance to high, low temperatures, aggressive components and chemicals;
• increased elasticity of the connection;
• neutral smell;
• transparency.

Any material that is waterproof keeps moisture from penetrating the glued area. Certain heat-resistant materials are capable of withstanding temperatures higher than +100 °C.

There are two kinds of mixture dry residue in terms of quantity.

1. Group A-flexible substance, 6-8%.
2. Group B-after drying, a less flexible seam is formed, 8-12%.

Rubber compositions are categorized based on the kind of synthetic materials used.

• Rubber. Means based on natural rubber have average adhesive abilities, poorly resist temperature changes and the effects of natural factors. They glue simple metal elements.
• Chloroprene. They add metals oxides for a reliable hitch with an iron base.
• Butadien-nitrile. Vulcanizing component – sulfur. Additionally there are tiurams. These are super -resistant substances with good adhesion in relation to rubber and metal details.
• Silicon. The composition hardens with the participation of tetrabutoksilane. Used to glue rubber among themselves. It is widely used in car repair shops in the repair of tires.

Glues for the home are packaged in tiny tubes or bottles. Industrial ones are applied exclusively with specialized equipment and are stored in banks, buckets, or drums.

What should be glue

The composition with improved adhesive properties can glue it firmly because its seam will be dependable and elastic. Furthermore considered:

• operating temperature of the glued part;
• humidity in the room;
• load on glued surfaces;
• What elastic properties should a part after gluing have;
• Chemical aggression in relation to the treated surfaces.

It is required to read the instructions, and the manufacturer has to state whether the composition is appropriate for metal alloys or rubber. A strong, waterproof seam should form after drying, protecting the fortress from extreme heat and cold.

Purchasing products like "liquid rubber" is worthwhile when gluing car parts together because they form a single plane with a treated surface that hides the seams from view. The mixture used to glue silicone rubber is labeled as being for elastic materials on the package.
