Silicone glue-sealant and its use in everyday life
In the construction and repair industry, the most different materials and means.
Silicone adhesive sealant is a versatile silicone-based compound that is popular with artisans. Due to the high degree of reliability, as well as its excellent qualities, it is also used for a number of industrial sectors - for example, in the automotive structure in order to fix automotive glass, as well as for sealing parts.
You should familiarize yourself in more detail with all the properties, the principle of the composition, and also the algorithm for working with them.
Description
What is silicone?
It is a high-strength type organosilicon polymer, as well as a chemical compound type, high molecular weight.
In appearance, liquid silicone will look like a resin, and synthetic rubber is used to create it. It was made in the middle of the 20th century and is now widely used. The most popular products based on it are sealant and glue. In the production of adhesives, in addition to silicone, other substances are also used, which can be called basic additives and fillers. What can be glued with such a tool and where is it used?
Silicone-based composition is perfect for gluing:
The scope of silicone is so wide that it is unrealistic to list all directions. In industry, it can be used to make dishes, kitchen utensils, for example, sets of baking tins, as well as bags for creating pastries. Silicone can be used to seal the bathtub, window glazing, it is indispensable in cosmetology, as well as in medicine.
Also, silicone adhesives are often used for the repair work of equipment, radio-type products, electronics, as well as for crafts. But the most popular tool in everyday life, construction, for repair work, especially in places where an increased degree of resistance to moisture is required.
There are no big differences between the products, and due to the composition often referred to as adhesive sealant. Features, cost, main line-up are so similar. But with a large number of additives and texture, they can differ from each other.
Typically, sealants are thicker and glue is thinner. There are differences in the form of release, the form of a bottle, a nozzle, because this material has a special purpose. Usually, adhesives are packed in small-sized tubes, and they can be applied without a construction gun. A construction metal gun is required to work with the sealant. Sealing of seams that have a large length, sealing pipes, windows, walls, plastic structures, and even glass is done with a sealant.
But gluing tile masonry, gluing corners, shoes, dishes, applying to self-adhesive adhesive tape for a bath can also be done with an adhesive.
Up to 50% of the composition of the material is presented as artificial rubber. Most builders prefer to use transparent silicone adhesive sealant, but there are white, black, and bright shades on sale, it all depends on the needs.
According to GOST, the tool may include the following components:
Many home remedies are sold as a one-part formulation. Only certain professional adhesives are sold as two-component adhesives complete with a hardener.
Due to the properties of silicone, the glue seam after hardening will become frost-resistant - it will retain its quality even in cold temperatures (up to -45 degrees). The stability of the seam is also too high under high-temperature exposure - up to +210 degrees. By the way. A number of formulations can be found commercially for use at lower and higher temperatures. At what temperature does the material melt, which is indicated on the package.
Certain products have a melting point above +300. . + 400 degrees.
Silicone compounds are more resistant to water, and this ability makes it possible to reliably glue aquariums, dishes, and use for glass. The glue is electrically conductive to a minimum, and it can even be called an isolate - it practically does not conduct electric current.
Other seam properties:
Only high-quality formulations are truly resistant to moisture, and also have the rest of the listed properties. If it productively includes cheap silicone, poor quality plasticizers, the service life can be reduced several times. It is convenient to use silicone material, it is moderately thick, and at the same time it will flow into the smallest cracks and pits. The product is non-toxic, safe for humans, unlike the popular Moment.
Skills for gluing products are not required, and the work is very simple. The material will dry out very quickly.
The rubber in the adhesive composition can be fluorosiloxane and siloxane. Polymerization of each of them will occur from contact with air, due to which the agent acquires a bond with the surface, becomes harder, but more elastic. So that nothing hardens ahead of time, silicone glue, like super-glue, or "liquid nails", which are released in a sealed container.
All silicone-based products are divided, depending on the components included in the composition, as well as the pH level, into the following types:
Among the disadvantages, you can indicate the high cost.
Most moisture resistant silicone sealant adhesives, most products contain antiseptics, and then they can be glued in places that are prone to rot and mold. Another difference between the funds is in the method of application, form of release, volume, and also in what is their cost and the manufacturing company.
Please carefully read the instructions for use. It is important to make sure that just such a material is suitable for a certain type of surface, and also the manufacturer always indicates this.
For example, if you have to glue metal products, you should make sure that there are no acids in the composition. For example, if you want to seal the seams on the tile, between the bathroom and the wall, the best option would be to purchase an acid-type adhesive. Subsequently, it will be easier to remove and renew using a remover (silicone cleaner). When repairing plumbing, many people prefer to buy a white sealant, while fabrics, household appliances, paper, kitchens are better suited for transparent material.
In general, there are several types of adhesives, buy the most suitable one:
Non-toxic, safe for plants, animals, and also makes it possible to glue joints and corners in the aquarium. Not afraid of ultraviolet rays, water, has high reliability.
It will be a sealant for joints, as well as for laying in equipment and cars.
They are quite stable, do not react to precipitation, as well as changes in temperature conditions.
Now let's talk about how to work with such a roster.
How to use silicone adhesive?
Difficulty with repairing different products will not appear, and even a beginner can handle it. But the effectiveness of the work will depend largely on how well the foundation is prepared. It is important that the substrate is clean, dry and smooth.
It must be degreased before use, and this will help improve the quality of adhesion. You can degrease the surface using any suitable means - a detergent solution, a special composition. After drying and degreasing, the edges of the joints can be pasted over with paper tape, and so it will turn out to avoid blots, blemishes, the layer will be applied evenly.
Then the order of work will be as follows:
Raising the room temperature by 5 degrees from room temperature will speed up the polymerization process in half. The thickness of the adhesive layer more than 2 cm will not make sense, since the product will not solidify in the depth of the seam.
Excess sealant should be removed immediately with a cloth and spatula.
The price of silicone glue-sealant is usually from 200 to 540 rubles per package with a volume of 330 to 500 ml, and also the cost will greatly depend on the manufacturer. Glue in a package of 10 to 30 ml will cost much less - from 30 to 110 rubles.
Below are the brands of the best manufacturers that are sold in the store:
It is used most often for gluing dishes, ceramics, and in everyday life it is needed to repair remotes and other rubber products. Withstand temperatures up to +250 degrees.
Waterproof and unstable glue, which is sold in a volume of 80 to 150 grams and 5-7 kg. Used for gas tanks, bodywork, engine, radiators, can even be used for the cooling system.
With proper use of products, the glue seam will serve for many years, but if necessary, you can replace all new layers of the product.
