Review and advantages of Abro brand sealants

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.

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 and 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 and areas of application

The manufacturer himself makes the main classification based on what substance is released during polymerization.

Acidic sealants have a vinegary odor. The material is widely used due to its versatility in the construction and repair of machine components; this type of product quickly polymerizes.

Acetic acid can destroy parts made of non-ferrous metals, which limits its use.

Neutral products are practically odorless, have excellent adhesion even to dirty surfaces, and do not cause a reaction with copper and aluminum.

The color of the packaging and silicone serves to easily determine the type of sealant. For rare use, it is important to study the instructions.

The manufacturer indicates that red, white, and transparent options do not contain artificially introduced pigment and have high shear and tensile strength.

Brief characteristics and areas of application of products of different colors :

• Black “works” in the temperature range from minus 40 to 260°C, and is used to improve the tightness of standard felt, paper and rubber gaskets and to form seals for thermostats, pumps, and other parts made of ferrous metals. During operation, the composition is resistant to vibrations.
• Blue , acid curing type. Used at the same temperatures as ferrous and also suitable for non-ferrous metals. There is a limitation - it is not suitable for sealing air sensors, as it releases acetic acid.
• Transparent is used to create gaskets up to 6 mm thick, operating at temperatures up to 260°C. Not destroyed by oils, transmission fluids and antifreeze. In everyday life it replaces sanitary products for seams.
• The red composition is stable up to 343°C and is distinguished by its high peel strength. The high temperature resistance allows this type to be used for valve cover gaskets, transmission parts, intake manifolds, engine pans and automatic transmissions.
• The gray version completely replaces the gaskets, i.e. the parts fit together directly. Can be used for sealing paper, felt and rubber gaskets. Safe for any metals, applicable for any units and parts with the exception of engine exhaust manifolds.
• Abro High Temperature Sealant looks like hardened copper, but there is actually no metal in it. Does not interact with metals, withstands heating up to 370°C, is resistant to stress, and is approved for sealing lambda sensors. Used for any units except the exhaust manifold.
• The white sealant is operational up to 260°C, resistant to oils, water, cooling system vapors, and technical fluids, except gasoline. These properties make the white type of seal universal.

The manufacturer categorically does not recommend Abro sealant for use in places of direct contact with gasoline, for example, for sealing fuel lines, tanks, pumps.

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.

ABRO transparent sealant: effective, versatile, easy to use

I'm used to servicing my car myself because it's not only cheaper, but also faster. To replace gaskets I use a special transparent sealant from Abro masters. The Abro company is an American brand that has proven itself well in the international market. The company produces high-quality car care products. I have been using formulations from Abro for several years now, and I am pleased with the products of this brand. Below I will tell you how I repaired a car with transparent sealant. asters automotive sealant

ABRO transparent sealant

Designed to replace or repair any gaskets found in the vehicle. This composition provides reliable adhesion that is not affected by moisture or other liquids. This distinguishes it favorably from water-soluble adhesives.

The product is colorless, easy to apply, dries quickly and is convenient to use. In addition to gaskets, you can use sealant to glue a headlight or glue glass, as well as perform a number of other small jobs where you need to achieve reliable adhesion of several parts.

Silicone has a dense consistency and does not spread over the surface being treated. After drying, it forms a tight connection, preventing air and moisture from passing through.

Main technical characteristics

The high popularity of transparent ABRO sealant is ensured by the presence of a number of positive properties:

1. Maintains high performance at temperatures up to 260 degrees Celsius.

2. Insensitive to most non-aggressive liquids. We are talking about water, antifreeze, and various types of oils. They are not capable of destroying the sealant layer.

3. Convenient tube size for one-time use. The product comes in a compact tube, which is intended for one-time use. There is enough content to carry out small and medium-sized work.

4. Wide scope of application. In addition to replacing gaskets, the product can be used for exhaust and intake manifolds, thermostat and other components. The composition is completely safe for oxygen sensors.

Abro masters sealant is supplied in small tubes without blisters, 32 grams in volume. I used it to install the optional brake light glass on a Nissan Xtrail. As a result, the glass settled like a glove, and I was pleased with the result. It has remained in place for several months now, having withstood several trips in the rain.

Mode of application:

Using ABRO clear sealant is easy. There are instructions on the tube, following which you can achieve reliable gluing of the parts. Let us consider the features of using the composition in more detail:

1. Before applying the product, the gluing areas must be cleaned of dust, dirt, sand, oil residues, etc. The composition can only be applied to clean and dry surfaces.

2. Remove the cap from the tube. Then we pierce the protective film.

3. Screw on the plastic spout. We take scissors and cut it to get the hole of the required size.

4. Apply silicone in a thin continuous layer to one of the surfaces to be glued.

5. Wait about 10 minutes for the silicone to dry, and then press the parts tightly together. We make sure that there are no gaps between the surfaces.

6. Remove any remaining product. To do this, you can use a rag soaked in vinegar.

When used correctly, ABRO transparent sealant provides a truly reliable and durable connection. This product turned out to be as effective as other products from the Abro company. The main thing is to wait for the sealant layer to dry, and only then connect the parts. The strongest possible grip will be guaranteed.

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.

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.

Features of removing Abro sealant

If the Abro sealant does not dry completely, it will not be difficult to remove it. This is achieved by using a rag soaked in alcohol. You just need to remove excess drips and stains with such a rag.

If the material from Abro has already undergone complete polymerization, it will only have to be cleaned mechanically. Remove it with a knife, sandpaper, blade or grinder. If the case is difficult, you can use the cleaner from the Ambro range.

It is a spray quencher for silicone sealants. In addition to sealant pastes, they can remove varnishes, paints, oils and glue without any problems.

To do this, you need to apply a spray to the area and after 10 minutes remove the remaining product with a special 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.
