All TechnoNICOL sealants are made on the basis of one-component and two-component compositions. Thanks to this content, they acquire high quality and constant elasticity. The most popular of them are polyurethane-based sealants, which acts as an elastic and viscous mass. When such a solution is applied to the surface, it polymerizes, forming a high-quality compound of materials.
Features of the
Today, craftsmen pay a lot of attention to the quality of the tightness of the seams, as well as different types of joints when assembling structures from a variety of materials. For such purposes, a popular composition is a sealant based on TechnoNICOL polyurethane, which is of medium modulus. This feature makes it possible to apply it in a wide variety of areas, for any type of material. It creates a high-quality and durable connection that does not allow moisture to pass through.
This type of brand composition can be used for the following purposes:
- for elastic sealing of joints of a structure made of light metal or steel;
- it can be used for high-quality sealing of tanks, containers and other similar objects;
- they are filled with vertical and horizontal joints of the compensation type;
- such a composition is often used for grouting joints after laying ceramic tiles, cable shafts, concrete floor slabs;
- used for the purpose of obtaining waterproof joints in the construction sector, as well as for the purpose of sealing in industry;
- such a composition can be used as a roofing adhesive.
The main feature of this material is the fact that it can be used not only for household needs., but also for industrial facilities. This is due to the fact that such a composition perfectly connects building elements from any type of material. It is also resistant to external aggressive influences, elasticity, and makes it possible to paint treated surfaces to match the color of the base.
It should also be noted that the use of TechnoNICOL sealant does not allow moisture to affect the structure.
The features include the following parameters of a branded sealant:
- increased elasticity after solidification of the composition;
- excellent adhesion to any type of surface;
- resistance to moisture;
- the speed of solidification and drying, if the composition is used correctly;
- resistance to different temperature indicators, for example, the composition is able to withstand frosts down to -45 degrees, but the base treatment itself must be carried out at a temperature not lower than -10;
- most sealants have a negative attitude to direct sunlight, and the TechnoNICOL composition is not afraid of such an influence;
- after applying a layer to the surface, the composition does not shrink;
- the material is safe, does not emit harmful substances into the environment, and does not affect the human body;
- the consumption of this material is economical;
- the connection with this compound is durable and reliable;
- a feature of this material is the possibility of staining it after drying, but the paint must be water-based.
Due to such a number of features and advantages, TechnoNICOL sealant is considered universal, which makes it popular among consumers. There are drawbacks, but they relate to hand protection and heat.
These nuances do not affect the quality and reliability of the sealant.
Views
The manufacturer "TechnoNICOL" manufactures an extensive range of sealing compounds, which have their own characteristics and various technical characteristics. Let's consider the main types of sealants.
Polyurethane-based composition
One-component polyurethane material is the most demanded. This is justified by the fact that it has excellent adhesion to any type of surface. For example, such a sealant adheres perfectly to wood, metal, concrete, brick, ceramics, plastic and other types of materials. Such a connection is of high quality, reliable, and also does not react to moisture and vibration. When exposed to moisture, this material acquires additional strength. It can be used at an air temperature of +5, but not higher than +30. No less effective and practical is a two-component composition based on polyurethane (2K).
When the composition hardens, it is able to withstand temperatures from -30 to +70 degrees. As for the use of such a sealant, it is necessary to clean and then dry the surface before starting work. It begins to harden after 2 hours, and complete hardening takes place with the calculation of a day per 3 mm of material layer.
Based on bitumen polymer
Such a tool is marked with number 4. This material is based on bitumen mixed with artificial rubber and mineral components. This two-component sealant is used to seal the seams of asphalt, concrete and airfield surfaces. It cures quickly. When dry, this sealant does not shrink, but remains elastic.
Bitumen-polymer composition of 3 types is produced:
- BP G25;
- BP G35;
- BP G50.
The first type is used in an environment where the air temperature cannot drop below -25 degrees. BP G35 is used in places where the temperature does not drop below -35, and BP G50 is used where the temperature indicator can drop below -42 degrees.
Based on mastic
Such a sealant is produced with the marking number 71. Typically, sealing mastic is used as a roofing material that can hold about 20 kg. They can repair the roof or glue the elements of the roof. It also has excellent adhesion to concrete and metal surfaces. Such a sealant does not allow water to pass through and is resistant to high temperatures, which allows it to be used as a membrane.
Silicone based
The silicone type of materials is used during construction work. It is recognized as a universal composition that is suitable for high-quality surface sealing, and therefore is relevant in a variety of areas. After application to the surface, it hardens quickly. When water gets on it or moisture is affected, the composition becomes even stronger and more elastic. It is a popular product that is sometimes used as an analogue of a rubber seal for various types of structures, for example, for PVC.
The curing speed of such a sealant is calculated taking into account a 2 mm layer for 1 day.
Colors
If we talk about the colors of the sealants produced by TechnoNICOL, they can be gray, white and black. So, a black composition is often used to seal cracks, gaps and joints between structures. Also, with the help of such a sealant, thermal insulation panels and air conditioning systems are glued together. The shelf life of the composition is about 15 years. The main disadvantage of this material is its dark color, due to which it cannot be used in all cases.
Gray and white sealants are popular today. Such formulations are the best option for use on any type of material. They do not shrink during solidification, have a high level of elasticity, are resistant to oil, and can also withstand aggressive environmental influences. Such sealants are made on the basis of thiokol, which is why they can be used in all weather conditions.
The main feature of the white sealant is the fact that after hardening it can be repainted in any desired shade, but the paint must be water-based.
Consumption
The consumption of materials produced by TechnoNicol is very economical. It should be noted that this parameter depends, first of all, on the size of the seam that needs to be closed. For example, the minimum packing is enough to "close" a joint 6 mm wide and 3 mm deep. These gaps are common in bathrooms. The consumer will need about 25 ml of sealant to carry out all the necessary types of work.
There are also large packages, for example, the composition of PU 600 ml. Such packaging will last for a long time. With its help, you can correct many shortcomings, for example, oblique seams, semicircular gaps between the bathroom and the tile, as well as any other problem areas.
Advice
The manufacturer "TechnoNICOL" produces various sealants, so the scope of their use is very wide.
These formulations are suitable for:
- repair work;
- used instead of a waterproofing layer;
- are used to eliminate empty gaps around communications;
- to align the seams when installing plastic structures;
- these types of sealants are used for many in the industry.
Experts recommend using the material in this order:
- you need to mix the material well;
- it is also necessary to clean the treated surface from dust and dirt, since such factors negatively affect the quality of adhesion of the composition to the surface;
- it is important not to forget to degrease the material;
- in the event that work must be carried out at sub-zero temperatures, the sealant must first be left in a warm room for a day;
- the composition is applied with a rubber or iron spatula, but it is necessary to wear protective equipment for hands and possible places where the composition may get;
- it is not recommended to add a solvent to the composition, although this will facilitate the work process, but will negatively affect its quality;
- when performing processing, you need to monitor the gaps (if there are gaps on the seam, this will affect the quality of the sealing);
- it is recommended to follow the instructions for use on the packaging with the sealant.
TechnoNICOL compounds can be used at low air temperatures, as well as in places of high humidity.
