Features of butyl sealants

Almost all people face the need for warming and sealing windows. This issue becomes especially acute with the onset of cold weather, when drafts from the windows are felt. To cope with the problem is quite easy: it is enough to 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? What is the difference between the butyl rubber product in the glass package and other varieties? What is the composition of the variants of hermabutyl?

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 sealant filler is half the composition of the material (as for high-quality hermetic materials). Butyl sealant has its own specifics, which consists in sealing window joints and joints.

Butyl and polyisobutylene sealant has a different composition, but their properties are very similar. It is thanks to a wide range of properties and advantages that these materials are in demand and used in the repair and production areas.

Any building material is endowed with advantages and disadvantages. Before you buy or apply a particular sealant, you need to examine 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 bases: it perfectly adheres to aluminum, glass, steel;
• low vapor permeability and thermal conductivity;

• increased degree of elasticity, strength;
• resistance to ultraviolet rays;
• affordable price range;
• excellent tolerability of different temperature regimes: 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 wet surface.

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

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

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

The main scope of application of butyl hermetic materials is the manufacture of double-glazed windows. With the help of hermetic seal gaps, joints, as well as connecting zones in various structures of wood, glass, metal.

The only disadvantage of butyl rubber sealant is that it cannot be used for internal work.

Heat sealant panels are glued together with sealant, air conditioning systems are sealed, and sometimes containers and vessels are sealed.

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

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 the seams of the car body;
• for sealing seams on water pipes;
• for waterproofing purposes;
• when warming window and balcony seams.

The composition of germabutyl includes: butyl rubber, mineral components, organic solvent, modifying additives.

It has the following advantages:

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

Butyl-rubber hermetic material "Vikar" is particularly popular because it has a number of properties and advantages. This is a homogeneous mass, which includes artificial rubber, bitumen, filler, solvent, technical additives.

It is durable, waterproof, elastic, has good adhesion to such bases as concrete, metal, tile, ceramics, PVC, natural stone. The sealant is durable, resistant to ultraviolet and temperature changes.

With it, perform:

• sealing joints, connecting joints in order to increase heat resistance (internal / external work is allowed);
• sandwich panel joint repair;
• roof sealing;
• sealing of ventilation systems, chimneys;
• sealing seams in vans, bodywork to prevent corrosion.

Also sealant "Vikar" is available in the form of a tape of different sizes and colors: gray, black, dark gray. The tape represents the bilateral self-adhesive material which is not absorbing moisture. It does not need to be heated during use. It is most often used for sealing joints of sandwich panels, stained glass windows, facades, rigid roofing, ventilation systems. It is used to connect the elements of vapor barrier, bonding and gluing cloths and parts, as well as a cushioning material in plumbing, ventilation, sewer systems.

Another quality butyl hermetic material manufactured by the American manufacturer Orgavyl. Its application area is somewhat different from other butyl sealants: it is used for automotive glass, to seal auto-optics (headlights).

Orgavyl Sealant is particularly 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 oily substances;
• non-toxic, odorless;
• endowed with good adhesive properties;
• does not take time to harden;
• does not stain the details of auto optics;
• prevents fogging of car headlights.

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

• clean the headlamp;
• slightly stretching, place on it a hermetic tape;
• heat it with a hair dryer and attach the glass, well pressed.

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