How to glue silicone, how to glue rubber to plastic, metal

Basic properties of silicone

Silicone is a soft synthetic material that is obtained by synthesizing polymers. It is quite practical, relatively durable and elastic. Such raw materials are used in various fields due to significant advantages, including:

resistance to high temperatures and temperature changes;
presence of water-repellent properties;
plastic;
resistance to various types of deformation and minor mechanical stress;
elementary processing and disinfection;
complete resistance to oxidation.

When is it necessary to glue glass in the oven?

As a rule, electric ovens and gas stoves have 2-3 heat-resistant glasses. The temperature inside the equipment during operation rises to +250 °C. Even if the glass is of high quality, over time it can crack or crumble. In addition to temperatures and their changes, there are other causes of failure:

Impacts, scratches, mechanical damage.
Action of steam, fat and other substances. If there are scratches or areas that have already been sealed, the risk increases.
Pyrolysis function, that is, high-temperature cleaning. This is an additional burden.

How to choose the right glue for silicone

The question often arises of how to glue silicone if a product made from it breaks at home. It is important to choose the right adhesive composition here. We'll talk about the criteria in this section. First of all, they make a choice based on operating conditions:

Universal. The most optimal adhesive option, which is suitable for joining at home and outdoors. Typically, such products are used to seal cracks or eliminate defects during repair work. This composition will retain its properties even with dramatic changes in temperature.
For outdoor work. This option is ideally used outdoors or on products that require strong hardening. These are the properties that the composition for street work has. The adhesive composition performs well in air.
Sealants. This is another special group of polymer adhesives. Such compositions can withstand exposure to moisture and various types of liquids. Under proper processing conditions, the connection with such glue will be long-lasting and waterproof.
Automotive. This adhesive composition is also called a “liquid gasket”. It copes with the tasks of gluing various gaskets when repairing car engines and chassis. It is not recommended for use in domestic conditions due to toxicity and unsafety.
Sanitary. Another composition for gluing silicone rubber, and it can be classified as a type of sealant. It is used for gluing flexible polymers, as well as for processing seams in bathrooms and other rooms exposed to high levels of humidity.
High temperature. This is a convenient composition that can now be found in every owner. Sold in the form of special sticks of different lengths, placed in a heat gun and melted by heating, after which it perfectly glues not only silicone, but also many other products.

Suitable brands of adhesives for silicone

Silicone rubber adhesive can be produced by different manufacturers. The highest quality products are listed in this section.

Klebfix. A popular adhesive for silicone products, which ideally glues not only silicone objects, but also aluminum alloy. The finished connection is quite strong and tear-resistant.
Permabond. Another equally functional material. It is used to join silicone with heterogeneous gaps, as well as other difficult-to-join objects. The composition can be applied in an automated way, especially if there is a need for gluing large objects.
Valmexinsc38. Product with increased strength, produced in Germany. Provides reliable connection of latex, natural silicone and even PVC-based items. After hardening, seams made with glue of this brand are not destroyed by water. The hardening time is three minutes.
Cosmofen CA 12. High-quality glue that can be used to glue silicone and other components. Sold in a package with a special dispenser. This composition is consumed economically and is stored for a long time.

For reliability, before using each brand of glue, it is necessary to prepare the product that needs repair. You can find out all the details in the section below.

Application

In the food industry, adhesive and sealant are necessary for processing components of industrial equipment:

fixing threaded connections;
sealing pipes, flanges;
fixing cylindrical assemblies, to which increased safety requirements apply;
restoration of worn parts that do not yet need urgent replacement.

Adhesive sealants vary in composition, therefore, depending on the type of production, a more heat-resistant, moisture-resistant or other lubricant that meets safety requirements is selected.

Glue Basics

There are a number of requirements that must be observed when working with glue for silicone restoration:

be sure to degrease the surfaces before applying glue; standard alcohol, white spirit, or acetone are suitable for this;
apply carefully, use a small amount of glue, as the residue can harden on the surface and ruin the appearance of the silicone item;
gluing should be performed by tightly pressing the two parts to each other and additionally holding them in this position for several seconds;
Carry out silicone repairs only in a well-ventilated area at a temperature of at least 25 degrees;

Do not allow direct contact of the skin of your hands with the adhesive composition, as the latter can cause serious burns.

If you follow all the recommendations listed, you will eventually get a strong connection without harm to your own health.
