Features of butyl sealants

Almost all people face the need to insulate and seal windows. This issue becomes especially acute with the onset of cold weather, when drafts from the windows are felt. Dealing with the problem is quite easy: just use sealing materials. It is in this area that butyl sealant is used.

Butyl sealant - what is it? What is its functionality? What are the main advantages and disadvantages? How does a butyl rubber product in a glass tube differ from other varieties? What is the composition of the hermabutyl variants?

Butyl sealant is a one-component thermoplastic mass based on synthetic rubber (polyisobutylene), on which the strength of the material and its consistency depend. The filler of the sealant is half of the composition of the material (as for quality hermetic materials). Butyl sealant has its own specificity, which consists in sealing window seams and joints.

Butyl and polyisobutylene sealants have different compositions, but their properties are very similar. It is due to a wide range of properties and advantages that these materials are in demand and are used in repair and production areas.

Any building material is endowed with advantages and disadvantages. Before buying or using this or that sealant, you need to study all the pros and cons of the material.

Among the advantages of butyl sealants are the following:

• no volatile components;
• high degree of adhesion to many substrates: it adheres perfectly to aluminum, glass, steel;
• low vapor permeability and thermal conductivity;

• increased degree of elasticity, strength;
• resistance to ultraviolet rays;
• affordable price range;
• excellent tolerance to different temperature conditions: from -55 to +100 degrees;

• long operational period;
• safety for human health and the environment;
• short setting time, hardening;
• the possibility of applying to a damp surface.

Along with the many advantages of a hermetic material, there are only a few disadvantages:

• available only in black;
• loss of tensile strength at negative temperatures;
• narrow range of applications.

The ratio of positive and negative qualities of butylene sealant suggests that the material is reliable and of high quality.

The main field of application of butyl hermetic materials is the manufacture of insulating glass units. With the help of sealants, gaps, joints, as well as connecting zones in various structures made of wood, glass, metal are sealed.

The only drawback of butyl rubber sealant is that it cannot be used for interior work.

The sealant is used to glue insulating panels, seal air conditioning systems, and sometimes seal containers and vessels.

Modern butyl rubber sealant is widely used in the construction industry: building construction, installation of communications, etc.

Hermabutyl is used:

• to isolate the contact of elements in building structures;
• for sealing joints between panels;
• for sealing seams;
• for anti-corrosion treatment of seams of the car body;
• for sealing joints on water pipes;
• for waterproofing purposes;
• when insulating window and balcony seams.

Hermabutyl contains: butyl rubber, mineral components, organic solvent, modifying additives.

It is endowed with the following advantages:

• increased elasticity;
• does not require heating and mixing during operation;
• high strength;
• a high degree of adhesion to many materials;
• resistance to different temperature conditions;
• the possibility of surface painting with paints.

Butyl rubber hermetic material "Vikar" is especially popular because it is endowed with a number of properties and advantages. It is a homogeneous mass, which includes artificial rubber, bitumen, filler, solvent, technical additives.

It is durable, waterproof, elastic, has good adhesion to substrates such as concrete, metal, tiles, ceramics, PVC, natural stone. The sealant is durable, UV and temperature resistant.

With its help, they perform:

• sealing joints, connecting seams in order to increase heat resistance (internal / external work is allowed);
• sealing the joints of sandwich panels;
• roof sealing;
• sealing of ventilation systems, chimneys;
• sealing of seams in car vans, bodies in order to prevent corrosion.

Also sealant "Vikar" is produced in the form of tape of different sizes and colors: gray, black, dark gray. The tape is a double-sided self-adhesive material that does not absorb moisture. It does not need to be heated during use. Most often it is used for sealing the joints of sandwich panels, stained glass windows, facades, rigid roofs, ventilation systems. It is used for connecting vapor barrier elements, gluing and gluing fabrics and parts, and also as a cushioning material in plumbing, ventilation, and sewer systems.

Another quality butyl hermetic material produced by the American manufacturer Orgavyl. Its area of ​​application is somewhat different from other butyl sealants: it is used for car glass, for sealing auto optics (headlights).

Orgavyl sealant is especially popular due to the fact that it:

• does not form cracks;
• does not dry out;
• provides high-quality sealing, waterproofing;

• can be used many times, just reheating is enough;
• has a high degree of moisture resistance;
• resistant to antifreeze and various oil substances;
• non-toxic, odorless;
• endowed with good adhesive properties;
• does not require time to harden;
• does not stain auto optics parts;
• prevents fogging of car headlights.

Besides all the benefits, the sealant is easy to use. For this you need:

• clean the headlight;
• stretching slightly, place an airtight tape on it;
• warm it up with a hair dryer and attach the glass, pressing well.

It is produced in the form of a black tape of a certain size.
