Step-by-step instructions on how and how you can glue silicone with silicone

Silicone is a soft material with a plastic structure that is widely used in a number of industrial and household applications. The question of how silicone and silicone can be glued often arises when products are damaged. To repair an item, you need to find the right glue and use it correctly.

Description and characteristics of silicone

As a result of the chemical synthesis of polymers, elastic silicone is obtained. There are several types of materials - elastomers, liquids, resins. The most common is rubbery silicone, which has been widely used since the middle of the last century.

The main characteristics of silicone are as follows:

1. Security. The material does not contain any toxic substances, so it is harmless to humans, animals and the environment.
2. Wide operating temperature range. The ability to maintain shape and quality at extreme temperatures expands the range of uses.
3. High elasticity. Even after long-term use, the material remains flexible, does not crumble or crack.
4. Water resistance.Silicone products can be used in places where there is frequent contact with liquid, as well as directly in an aqueous environment.
5. Inert to microbes. Exposure to pests does not affect the structure and appearance of silicone. In addition, disinfection can be carried out easily if necessary.

What products can be glued

If you follow the standard rules, it will be possible to glue any product, including a watch strap, children's toys, building components (seals, rings), medical tubes. The result of the repair directly depends on a number of factors, including the current condition of the product, the degree of damage, the adhesive solution used and the accuracy of the work.

Adhesive Selection

Several types of glues are suitable for the restoration of silicone products. To select the desired composition, it is recommended to familiarize yourself with the features of the available options and dwell on the suitable one, taking into account the characteristics of the product. Typically, silicone sealant or cyanoacrylate glue is used to join the parts. Such solutions reliably eliminate defects and firmly anchor surfaces.

A good adhesion result is ensured by an adhesive that meets the following requirements:

• elasticity and strength - the composition forms a seam that is not damaged by external influences and vibration load;
• optimal consistency - the density of the mixture to penetrate hard-to-reach areas and fill small gaps;
• the ability to withstand high temperatures - just like silicone itself, the glue must withstand heat without losing its properties;
• ease of use - convenience is affected by the packaging of the substance and the method of application;
• rapid polymerization - a high-quality solution can harden in a few hours.

Silicone sealant adhesives

Elastic silicone sealant is made from silicon, which is in the form of quartz or sand. First, polymers are created from the material, which serve as the basis for the sealant. The starting material determines the key parameters of the putty. The main feature is a high tensile capacity, which allows the use of a putty for working with loose joints. The material compensates for deformation at the joints and does not collapse under external influences.

Putty can be used for household and industrial purposes, as it is able to withstand ambient temperatures from -50 to +200 degrees.

Special types of sealants with increased heat resistance can be heated up to 300 degrees. In addition, the possibility of widespread use is associated with the resistance of the putty to the negative effects of ultraviolet rays, cleaning agents and moisture.

Cyanoacrylate adhesives

Cyanoacrylate solutions are based on alpha-cyanoacrylic acid esters. As additional components, plasticizers are used to adjust viscosity, and stabilizers to improve adhesion. Depending on the brand of cyanoacrylate solution, modifying components may be present in it, which are responsible for the resistance of the formed seam to moisture and heat.

Cyanoacrylate formulations exhibit resistance to organic solvents and electrical insulation properties.To dissolve the applied glue after hardening, treatment with specialized substances will be required.

The consumption of glue is slow, which reduces the cost of restoration work.

popular brands

When choosing an adhesive, it will not be superfluous to study the products of the best manufacturers. Among popular brands there are options with an affordable price and optimal characteristics for working with silicone products.

VALMEXINsc38

VALMEXINSC38 glue from the German company Rema is designed for express repair and restoration of silicone products, regardless of their size and condition. The solution is economically consumed and easy to use. VALMEXINsc38 is formulated with three solvents.

COSMOFEN CA 12

Composition Cosmofen CA 12 is a single-component liquid adhesive with a transparent structure and low viscosity. The created glue line acquires resistance to atmospheric precipitation and temperature extremes.

Mortar is not limited to household repairs and finds use in industrial applications.

Due to the possibility of gluing many types of surfaces, Cosmofen CA 12 is considered universal. The adhesive is suitable for working with small parts of silicone products and where quick bonding of surfaces is required. It is not recommended to use this brand only when working with porous surfaces and products that have been in contact with water for a long time.

ELASTOSIL E43

Elastofil E43 adhesive is a one-component, self-leveling rubber that cures at room temperature and has high mechanical properties. The substance is used for working with silicone products and for adhering silicone to the surfaces of other materials. Elastofil branded product features include:

• acetate curing method;
• adhesion without the use of primers;
• self-leveling after application.

The universal solution provides airtightness and electrical insulation, withstands extreme temperatures and vibration loads and does not lose its original characteristics over time. Thanks to the packaging with tip, the solution is practical for occasional application.

Safety precautions when working with glue

When gluing silicone products, it is recommended to familiarize yourself with safety precautions in advance. Following simple rules will help avoid dangerous situations. Basic safety rules are as follows:

• work with glue is carried out in a well-ventilated place;
• in order not to inhale the vapors of the substance, you can use a respirator;
• to protect hands from accidental contact with the glue solution, wear rubber gloves;
• throughout the working process, the ambient temperature should be between 15 and 25 degrees;
• if the humidity in the room exceeds the 60% mark, it is better to work in another place, as this can affect the quality of the seam.

Home Technology

To glue parts of a silicone product to each other, you need to follow step-by-step instructions. Before starting work, the surfaces are thoroughly cleaned of dirt and dust, after which they are left to dry. The product to be glued is covered with a thin layer of adhesive solution and applied to the second surface.

If it is necessary to connect silicone to metal, the instructions remain the same.

Most types of adhesives dry at room temperature. It is recommended not to use the pasted product within 24 hours of work.If the seam is uneven, it is permissible to separate the surfaces with chemicals and redo the work.
