Service station workers and car owners are increasingly purchasing Abro sealant because it is superior in quality to similar products. TM Abro produces compounds for the purpose of servicing and repairing vehicles. Sealants are useful and important in difficult situations when it is not possible to contact a service center or immediate repair of a breakdown is required.
Scope of application of sealants
Abro sealant is intended for repair, partial or complete replacement of any type of car gaskets, for sealing joints, filling seams and gluing glass. It is suitable for working with trucks, passenger vehicles and other equipment.
When applied to surfaces, the sealant can take the desired shape and withstands squeezing, stretching, and movement. "Abro" is not afraid of water and oils, auto chemicals and petroleum products, so it is ideal as a car product.
Area of use of sealants
Abro sealants are used when repairing cars or replacing many types of car gaskets. Sealing compounds can take any form and can easily withstand movement, compression, and stretching; they are not damaged by contact with water, are not washed out, and their structure is not damaged by contact with brake fluids, gasoline and oil.
The scope of application of Abro sealants is the connection of all kinds of seams, joints; high-temperature material is used in places where parts are heated to extremely high temperatures. In addition, Abro products are used for gluing car windows.
Abro sealants can be used for cars and trucks and any other equipment. Since the materials are not afraid of petroleum products, they are suitable specifically for car repairs.
Types of Abro sealants
Depending on the composition and curing characteristics, all Abro sealants are divided into several groups.
High temperature
This sealant can withstand heating up to +371 degrees, and is characterized by a high tensile strength (14.55 kg/sq. cm). This silicone composition has a red color due to the presence of a finely dispersed pigment of the appropriate shade, and does not contain metals.
Due to the absence of metal particles, it boasts electrical insulating properties. Red sealant does not contain acids and does not emit harmful substances when heated, but is not suitable for surfaces that come into contact with gasoline.
Other characteristics of the product:
- retains its shape during vibration, pulsation,
- withstands destruction
- drying within 24 hours
- gives an even flexible seam after polymerization,
- allows you to make gaskets up to 6 mm thick.
Silicone acid
A by-product of polymerization is the release of acetic acid, which is present in their composition. After application, you can immediately notice an unpleasant sour odor emanating from the sealant. The price of such products is the least high, so they are the most popular for forming gaskets in auto repair.
The properties and technical parameters of silicone acid sealants are as follows:
- optimal curing speed - up to 24 hours,
- ease of use,
- operation at temperatures up to +260 degrees,
- high degree of adhesion to materials.
These products should be used with caution when working with metal substrates - in some cases they can provoke corrosion. Most of all, such compositions are suitable for working with different types of plastic.
Silicone neutral
Neutral sealants do not contain acids, therefore they do not react with metals and are suitable for working with iron, copper, and various alloys. Silicone-based products can be used at temperatures up to +200...+260 degrees, and those containing copper dust can withstand temperatures up to +343 degrees. Sealants are compatible with any technical fluids, exhibit high adhesion to all surfaces, and are almost odorless.
Series 1100 and 1200
Sealants from these series have similar characteristics. They are operated in a temperature range of –50…+200 degrees and can be used for interior and exterior work. The compositions are excellent for forming gaskets, creating insulation, and sealing seams on products made of rubber, wood, metal, ceramics and other materials.
Sealing agents include antifungal and antiseptic components that prevent the growth of microbes and mold. The sealants of the series are moisture resistant, not afraid of vibrations, deformations: the seam remains flexible even when stretched by 25%. They are available in white, black, transparent versions.
Varieties
Abro produces many different types of sealants, each of which is used for specific purposes. All products are divided into several groups or types, depending on the components included in the sealants. Manufactured:
- high temperature;
- acid silicone;
- neutral silicone;
- antiseptic sealants.
They also produce sealing compounds, distinguished by colors:
- red;
- black;
- transparent;
- white;
- blue.
Next, their main properties, characteristics and areas of application will be discussed.
High temperature
This type of sealant can withstand heating up to a temperature of 370 degrees, and these compositions have a high tensile strength, which is 14.55 kg/sq. see High-temperature mixtures - for example, Abro red sealant, which does not contain metals. Silicone red sealant is high-temperature; it contains a finely dispersed pigment, thanks to which the substance can withstand extremely high temperatures.
During polymerization and drying there is no unpleasant odor and no acetic acid is released. High temperature substances are not suitable for repairing parts that come into contact with gasoline. Red sealants do not contain any acids that would be released during heating. In addition, when heated, no harmful or toxic substances are released into the air; the composition has electrical insulating properties. Here are the main characteristics of high-temperature products:
- retain their shape during vibrations;
- able to withstand destructive influences;
- dry within 24 hours after application;
- after polymerization, the seam is flexible and smooth;
- The solution can be applied with a thickness of no more than 6 millimeters.
They produce Abro sealants that can withstand high temperatures in different packages, from 42 to 310 grams. To apply one sealing seam or replace a gasket, it is enough to purchase a tube weighing 85 g.
Silicone acid
These products are used when replacing gaskets, seals, insulation, and during other auto repair work. During polymerization, Abro silicone sealants release acetic acid contained in the substance; this acid has a strong, unpleasant odor. This product has a minimal price compared to other Abro sealing compounds, so it is most popular for creating silicone gaskets during car repairs. Here are the main properties of acidic silicone products:
- dries in 24 hours;
- can be operated at high temperatures, maximum 260 degrees;
- has a high adhesion rate to different types of surfaces.
It is important to carefully apply these materials to metal parts of the car, since in some cases acetic acid causes corrosion of the metal. These sealants are more suitable for application to various plastics.
Silicone neutral
One of the representatives of this product is the Abro 999 composition, which is suitable for replacing any car gaskets. These Abro sealants do not contain any acids, therefore do not react with various metals and are suitable for application to alloys, copper, iron, aluminum and others. They can be heated to a temperature of 260 degrees, and if the substance includes copper dust, then it can be heated to a temperature of 340 degrees.
No technical liquids or petroleum products (except gasoline) damage these materials, they have a high rate of adhesion to any type of surface, and do not emit odor during application and polymerization.
Series 1100 and 1200
Abro 1200 and 1100 have similar properties. They can be used at temperatures from -50 to +200 degrees, they are applied to the external and internal parts of the machine. These sealants create high-quality gaskets, a high degree of insulation, and are suitable for sealing seams on metal, wood, rubber, ceramic and other surfaces.
These sealants contain antiseptic and antifungal additives that prevent the spread of mold and mildew. These sealants have good moisture resistance, they are not afraid of vibration, and they do not deform under load. Sealed seams are flexible even when the material is stretched 25 percent. These products are made in colorless, black and white. Can be used to insulate parts made of rubber, wood, duralumin, various metals and even clay.
Red sealants
They are produced in different packages, different weights, they are high-temperature, can heat up to a temperature of 370 degrees. Most often, red materials are used to create gaskets:
- valves;
- pumps;
- intake manifolds;
- gearboxes;
- thermostats.
In addition, red products are suitable for repairing gearboxes, various sensors, pallets and other components and assemblies that heat up to high temperatures. The compositions are absolutely safe for metal, cork, felt and rubber, and do not harm oxygen sensors.
Black sealants
In terms of their area of use, they are similar to red compounds; they can withstand heating up to a temperature of 343 degrees, but in terms of strength they are worse than red products. Abro black silicone sealants are safe for any materials, have a high elasticity rate, and are suitable for quickly creating any type of car gaskets.
After drying, the seams are resistant to vibrations and deformations; they do not crack or become damaged by exposure to engine and transmission oil or antifreeze. Ferrous products are excellent for use on ferrous metals, used as gaskets for water pumps and thermostats, and are non-rusting and non-corrosive.
Transparent means
These silicone materials are made on an acid basis, they do not contain any additional components or additives, and can withstand temperatures of a maximum of 260 degrees. They have a high tensile strength, resistance to oils and technical fluids.
Clear sealants are used for felt, rubber and cork. They can be used both for auto repair and for domestic use. The elastic pads formed by this product have a maximum thickness of 6 mm and can withstand shear, compression and stretching without damage.
Gray sealants
They have a high elasticity rate and a fairly good tensile strength. These sealants are neutral, do not emit any odors during application and curing, and do not adversely affect any automotive sensors.
Previously, gray substances were used to seal parts of Japanese cars, but today these compounds are successfully used for all brands of cars. Although these sealing substances are not damaged by oils and technical fluids, they are adversely affected by gasoline.
Types of ABRO sealants by color
For ease of selection and depending on the added components, sealants of this brand vary in color.
Red sealant
Red sealant-gasket is available in tubes of 42.5, 85, 226, 310 g and is considered high-temperature, as it can withstand heat up to +371 degrees. Most often, the product is used to form gaskets on:
- valves,
- sediments,
- intake manifolds,
- thermostats,
- gearboxes.
The sealant is also suitable for assembling automatic transmissions, repairing pans, sensors, and sealing other heated connections and assemblies. The product can be used to strengthen existing gaskets made of rubber, felt, or cork. It does not harm the oxygen sensor and is suitable for their restoration, completely safe for any metals.
Black sealant
The black Abro sealant is similar in terms of use to red, because thanks to the presence of silicon, it can also withstand heating up to +343 degrees, although it has lower tensile strength (up to 16.87 kg/sq. cm).
This neutral composition is safe for any surface, has maximum elasticity, and is designed for rapid formation and replacement of all types of automotive gaskets.
The finished seams will be resistant to deformation, will not crack over time, and will not collapse from the action of:
- transmission oils,
- motor oils,
- antifreeze.
Black sealant is excellent for thermostat gaskets and water pumps that are made of ferrous metals - it does not provoke corrosive processes.
Transparent sealant
Multi-purpose colorless silicone composition has an acid base. It does not include additional pigments or additives, and is considered medium-temperature (withstands heating up to +260 degrees). The product is characterized by high tensile strength, resistant to oils and technical fluids.
Transparent sealant can be used to seal gaskets made of felt, cork, rubber, but can also replace any sanitary sealant in everyday life and auto repair. It forms an elastic gasket up to 6 mm thick, which perfectly withstands compression, stretching, and shear.
Gray sealant
Gray silicone sealant also boasts high elasticity and has a good tensile strength (16.87 kg/sq. cm). The neutral composition does not emit acid vapors during the solidification process and does not have a negative effect on lambda probes or other sensors.
Initially, gray “Abro” was used to form gaskets in Japanese cars, but it is no less suitable for all other brands of cars. The product is destroyed only by the action of gasoline, while without any problems it can withstand contact with any other automotive fluids.
White sealant
This is a quickly hardening product based on titanium and silicon dioxides that can withstand heating up to +260 degrees. The sealant is resistant to antifreeze, transmission oils, and water. As it polymerizes, it forms an elastic but very durable gasket of the desired shape, which can replace a damaged seal. The white sealant does not deform, does not leak from the place of application, and does not crack over time.
Blue sealant
This product has an acidic type of curing, so during polymerization it releases acetic acid vapors. You need to work with it with well-organized ventilation, or better yet, in the open air. It can withstand heating up to +260 degrees and freezing down to –42 degrees, its tensile strength is 16.87 kg/sq. see. Blue sealant can be used to seal any components and joints of a car, and can be used to form gaskets for pumps, thermostats and other parts.
How to use Abro?
To improve the adhesion of the sealant to the base, you need to thoroughly clean the part - remove the old coating, worn gasket, using a scraper or a special solvent. Next, the procedure will be as follows:
- open the composition by removing the nozzle and piercing the foil,
- put the nozzle back on, having previously trimmed the tip and made a hole of the required size,
- apply the product in a layer of up to 6 mm, avoiding the areas where the bolts are fixed,
- dry the new gasket for 10 minutes,
- assemble the product without over-tightening the bolts,
- leave the part for 24 hours until complete polymerization, then it can be put into operation.
Mode of application
Working with the compositions of the “color” series in blisters and tubes for all sealants includes the following main steps:
- It is necessary to remove the remains of the old seal, clean and degrease the surface
- Remove the cap and pierce the protective foil. If necessary, install the nozzle
- The tip of the nozzle is cut off in such a way as to obtain a “sausage” of sealant of the desired size and shape
- The composition is applied to the mating surface. Usually a layer of sealant 2–3 mm thick is formed
- After 10 minutes you can assemble
- At room temperature, the formed gasket under the influence of atmospheric moisture completely polymerizes in 24 hours
To work with packaging in tubes, special mounting guns are used.
How to remove ABRO compounds?
If the product has not yet dried, it is not difficult to remove it. You just need to wipe off any excess, drip or stain using a cloth soaked in alcohol. The composition, which has already undergone polymerization, will have to be removed mechanically. It is cleaned off with a blade, knife, sandpaper, or grinder.
In difficult cases, you can buy a special cleaner from the Abro line (removal of silicone sealants) in the form of a spray. In addition to sealing pastes, you can easily wipe off paint, varnish, oil, and glue with it. It is enough to spray the problem area, and after 10 minutes remove the softened product with a spatula.
Precautionary measures
To carry out all work without risk to health, you must follow the manufacturer’s advice. Due to the release of acid vapors by some varieties of Abro, you only need to work with a mask, glasses, and wear gloves on your hands to avoid burns and allergies.
If the product gets on the skin, it should be immediately washed with soap and water, and if it gets into the eyes and mucous membranes, immediately consult a doctor after washing. It is important to ventilate the room well during and after work. Tubes with sealants should be stored out of the reach of children, in a cool, dark place.
Any sealing agent from the Abro line allows you to quickly and with minimal labor costs eliminate cracks, leaks, seal holes and form gaskets. The repair of the machine will be successful, and the finished joint will serve for many years without deforming or collapsing from the influence of unfavorable factors.
