Silicone sealant "Moment": the pros and cons
The need for tightness can be found not only in the field of production, but also in living conditions. The popularity of sealing with the help of “Moment” silicone sealant is conditioned by the aesthetic appearance and reliability of the seams. In our time, there are quite a few sealing compounds, but Moment sealants are considered the most popular.
Special features
Universal "Moment" is a popular sealant, which consists of many components.
And these are the substances:
- polymeric silicone;
- thixotropic addition of silicon oxide;
- acetoxysilane is part of such a sealant;
- antifungal component.
In the markets today, you can find a variety of compositions of adhesives brand brand "Moment". And also this company produces mounting foam and self-adhesive tape.
The main features of the moment sealants are:
- plasticity of the material after solidification;
- increased linkage with the treated material;
- resistance to temperature extremes and resistance to mechanical loads;
- not exposed to moisture;
- long term use of the surface after treatment with the composition;
- cost, which is low;
- resistance to external influences;
- and the sealant also meets all hygiene and environmental requirements.
The advantages that a high-temperature sealant has are difficult to overestimate, it has a short period of drying, it is colorless, which makes it possible to use it even for mirrors. Technical characteristics make it possible to use heat-resistant material in the bathroom.
It has a “moment” and disadvantages, but they mainly concern the very surface treatment, which is not prepared for work.
Types and characteristics
All sealants today are divided into only 2 main types:
- Single component composition. This type is sold in any hardware store and is one of the most common. Formulations of this type are sold in metal or polyethylene tubes. Hardens such a component due to the presence of moisture in the air.The main disadvantage of this type is high-speed hardening, but only if the surface is treated with a thin layer. And if the layer is more than 1.2 cm, then the sealant freezes for a long time.
- Two-component type. Such mixtures harden in any layer, but the cost of such a composition is higher, since they are mainly used for industrial purposes.
Sealants "Moment" are one-component types, as they are intended for domestic use.
Manufacturer "Moment" manufactures two types of sealants. The first type are silicone-based sealants, and the second type is made on the basis of an acrylic water dispersion.
Acrylic-based sealants are more resistant to frost and to various adhesions of treated surfaces. The main disadvantage of acrylic compositions is the inability to use in an environment with constant moisture. As for the color of such a sealant, it is mainly white.
Silicone sealant is manufactured on the basis of a rubber polymer. Such a component makes the mixture more elastic and makes it possible to solidify in a short time even at room temperature.Due to this characteristic, Moment's silicone sealants are sold in special plastic tubes, which retain its liquid and plastic state for some time after production. Tubes can be produced with a volume of 85 ml to 250 ml.
If you separate the compositions, starting from the scope of use, they are building, automotive and special.
According to their composition, they are divided into two types:
- Neutral. Alcohol is added to the composition of this material instead of acetic acid, and thus a slightly less pungent odor is obtained. They can be used outside and indoors. Apply such mixtures in the field of shipbuilding, for sealing freezers, they can be transparent and white.
- Universal Sealants. The manufacture of such a composition takes place with the addition of acetic mixture, which gives an unpleasant and pungent smell, and when interacting with non-ferrous metal, cement and similar materials, which include alkali, causes corrosion. This type of sealant is produced in white or transparent color. It can be used for internal processing, that is, indoors, and for outdoor work, as it is moisture and heat resistant.The cost of such a composition is lower than neutral.
Moment Company manufactures a sealant that has a silicone base, but at the same time provides a reverse surface triple protection against corrosion, mold and fungus. The warranty period of such protection is about 5 years. If it is not frozen yet, it can easily be removed with a sponge.
And also the company Henkel produces sealant "Moment Germent", it can be used for both domestic and professional use. This sealant is divided into several types:
- Premium white, which is highly resistant to moisture, and consists of silicone. This type can be called the most heat-resistant.
- The next type, which is made on the basis of silicone and sodium silicate, does an excellent job with oil, gasoline, high temperature, which can reach 300 degrees. It dries pretty quickly, and its color can even be red.
- Type of sealant Sanitary is used for the manufacture of glazing shower cubicles and baths, but it can not be used for processing stone and rusty surfaces, the rate of hardening about 15 minutes.
- Aquarium view, used for processing painted and glass surfaces that are subject to frequent vibrations.It is popular because it has a high level of moisture resistance, and the color of this composition is extremely transparent.
The gray sealant which is produced on the basis of polyurethane enters the same series of the materials "Moment". It is often used as a trowel for moving joints and as an adhesive for shingles. It is resistant to moisture, acids, alkalis, water and similar negative factors. But it has a disadvantage, as it burns out in direct sunlight and for some time loses its elasticity.
Consumption
Any sealant "Moment" can be used for surface treatment at a temperature not lower than + 6 degrees and not higher than + 40 degrees. Apply it to the pre-prepared surface, which is cleaned of rust, dirt, oil, dust and similar elements. Although such sealants do not have adhesion, it is better to degrease the surface for a better fit. The seam layer must be at least 5 mm and not more than 1.2 cm.
The consumption of silicone sealant depends on the depth of the gap and the thickness of the layer. In order to know the consumption of material, you can use the online calculators on any construction site.And also on each package it is indicated what area will be enough money from one package. For example, if you have a seam 6 mm wide and 3 mm deep, with these parameters you will need on average 20 ml of silicone sealant per 1 meter of seam.
If you have applied a layer of sealant to the surface, but not in the way necessary, then it should be wiped with a dry sponge or cloth, but before it starts to harden and harden. If it hardens, then it can only be removed mechanically. In the event that the sealant accidentally fell on the hands or on the unnecessary place, then it must be removed with a solvent.
Tips
The main criterion for the correct choice of sealant is a comparison of different manufacturers according to the property of the composition and the preliminary determination of its scope. But experts advise to make a start from some more criteria:
- From the presence or absence of a sealant in the composition of the coloring matter. If there is no dye in the sealant, then after complete solidification it becomes transparent. This type of sealant can be used as an adhesive.
- Sealant packaging volume. If you need to process windows, then it is relevant and better to buy a sealant with a capacity of 85 ml,This volume is quite enough to handle 1 window, and if you have more windows, then it is more advisable to buy a 280 ml sealant package than to buy 4 small packages. Thus, you significantly save finances.
Since every year Henkel improves its products, the Moment brand has become popular not only in our country, but throughout the world. Sealant of this brand has reliability, high quality and durability. And also such goods have quite acceptable cost.
But according to the recommendations of experts, it is not worth saving and neglecting your health, and it is better to choose a neutral type of sealants “Moment”, which include alcohol instead of acetic acid. Such a composition, of course, is more expensive, but it’s better not to save on safety.
During the execution of works it is necessary to air the room, as well as observe the other precautions.
