How to choose silicone glue and use it correctly?
Content:
When it comes to sealing the joint when gluing parts, there is no better material for this than silicone glue. It is a special compound that may vary in composition, properties and characteristics. These points must be taken into account before applying silicone products in everyday life.
Features of Silicone Glue
Silicone glue is a compound that contains various catalysts, hardeners, fillers and, of course, rubber. A feature of this type of glue is the main component in its composition, namely silicone. Since the invention of silicone, it has been widely used not only in industry, but also in everyday life.
Due to the main component of silicone glue, it is multitasking, versatile and reliable. With it, you can not only glue objects from various materials, but also seal the seams. On sale you can find a type of silicone glue - a sealant, although there is not much difference in their composition and functions.
Composition
For a person who does not understand chemistry, the composition of silicone glue will sound like a set of obscure terms. Therefore, we omit the chemical formulas - the composition of the adhesive is as follows:
- silicone rubber;
- strength amplifier;
- vulcanizer;
- adhesive;
- plasticizer;
- dye.
The uniqueness of this glue lies in the fact that it contains silicone rubber not only in the base, but also in the hardener. The dye in the composition is contained only in the case when the silicone needs to provide an opaque texture.
Another interesting element in the composition of silicone glue is adhesive. This substance, due to which the connection of parts is carried out.
Silicone Adhesive Properties
Due to the difference in composition, the properties of the adhesive of different companies may vary. But there are a number of features that are characteristic of absolute all compounds based on silicone.
- Consistency. Silicone is a material that has firmness and elasticity. Therefore, silicone-based glue has a dense consistency and at the same time fills all the recesses on the distributed surface.
- High connecting ability. Silicone glue is suitable for joining parts from various materials, such as wood, glass, ceramics, etc.
- Security. The composition of silicone glue is absolutely non-toxic. Therefore, there are no special safety requirements when working with it.
- Drying speed. As a rule, this chemical composition hardens within a few hours after application. However, for the final polymerization, it is necessary to wait about 24 hours.
- Ease of use. To work with silicone glue, you do not need to use special equipment and have special skills. These compounds are sold in almost all construction stores.
Important!
A special glue production formulation of some manufacturers is able to improve its standard properties and add a number of advantages, such as water resistance, heat resistance and corrosion protection of the material.
By its properties, silicone glue is an absolutely unique material. It is convenient to use both for large-scale repairs and for solving some everyday tasks. But for this it is necessary to know its purpose.
Purpose of silicone glue
One of the features that were listed earlier is multitasking.This means that this composition has more than one purpose and can be used in different situations.
The purpose of silicone glue include:
- bonding parts from various materials;
- joint sealing;
- creating a silicone gasket.
The seams that are obtained using silicone glue have a lot of advantages. For example, when gluing parts, you don’t have to worry that water will leak through the joint formed. Silicone seam is completely waterproof and also resistant to ultraviolet rays. In many cases, the fact that the hardened silicone is completely transparent will be a big plus.
It is worth mentioning about the special compositions of glue, which, in addition to their main function, also have an antiseptic and fungicidal effect on the material in contact with it. Standard temperature conditions in which the adhesive retains its strength and reliability - from -40aboutC to +200aboutC. If you plan to use a glued product at higher or lower temperatures, you should pay attention to compositions that are resistant to aggressive environmental conditions.
Types of Silicone Glue
Silicone glue is divided into two large groups: one-component and two-component. One-component glue is most often used for domestic needs, in particular during construction and repair, as well as for crafts, since no extra manipulations are necessary to harden it. Simply apply it to the surface.
As for the two-component compositions, they are more in demand in industry. Their main feature is that an additional catalyst is required for polymerization. This means that for the use of this glue it is necessary to mix two different compositions and only then apply them to the cleaned part.
Another common classification allows you to divide one-component silicone compounds into acidic and neutral. Their difference is again in the composition. Acidic acids contain acetic acid, and neutral ones contain alcohol or ketoxime. But it is worth noting that acetic acid-based formulations are not suitable for joining metal, concrete, cement and marble parts.
Acidic compounds have a low price, but at the same time they have several disadvantages: incompatibility with many materials and the stimulation of an accelerated corrosion process.
Brands and Costs
On sale you can find a fairly wide range of different compounds, which will differ in price and quality. To choose the most suitable option for yourself, you can analyze the most popular brands of glue and choose the most suitable one from them.
| Title | View | Application area | Cost |
|---|---|---|---|
| Repair Silicone Sealant, 260 ml | One component | Glass, ceramic, aluminum, painted and varnished surfaces | 150 rubles |
| Moment mounting sealant, 300 ml | One-component high temperature | Glass, ceramics, metal, aluminum, painted and varnished surfaces | 377 rubles |
| Penosil U Silicone Sealant, 310 ml | One Component Acid | Wood, porcelain, ceramics, plastic | 237 rubles |
| Profilyuks silicone sealant, 260 ml | One-component universal | Wood, ceramics, glass, aluminum | 148 rubles |
| Silicone Remontix Sanitary Seal, 310 ml | One-component fungicides | Glass, ceramic, aluminum, painted and varnished surfaces | 198 rubles |
| Sanitary sealant "Bison", 280 ml | One-component waterproof | Glass, ceramic, aluminum, painted and varnished surfaces | 212 rubles |
The prices in the table are approximate and may vary depending on the seller. When choosing glue, you should not focus only on its cost. For a deliberate purchase, you should learn how to choose a glue or silicone based sealant.
How to choose the right composition?
Once in the building materials store, you can really get confused when choosing the right composition.
To avoid a rash decision and a meaningless waste of money, you should pay attention to the following points.
- Production date. On sale often found sealants with expired shelf life. Whatever the quality of the selected composition, after the expiration date it will lose its useful properties.
- The manufacturer. Preference should be given to already established manufacturers. Compounds that contain cheap and low-quality dyes and perfumes can reduce the reliability of the seam.
- Packaging. Sealants are available in small tubes, which may be damaged due to violation of transportation rules. Packaging of high-quality sealant should be complete and free from defects.
- Purpose of use. The purpose and purpose of silicone glue should match. Otherwise, no one can guarantee a reliable connection.
- Place of acquisition. Buying sealant is best in proven construction stores, where there is all the necessary documentation for the goods sold.
Guided by these parameters, you can easily get a good silicone composition. The price for it is quite small, so do not try to save money at the expense of the quality of the connector.
Silicone glue is a composition that allows you to solve many problems associated with construction and repair. Thanks to its unique properties, you can not worry about the reliability of the seams of the connected parts for a long time. The main thing is not to rush to the choice.
