Rating of effective converters of rust with zinc: rules of use, prices, customer opinions

Products belonging to the category of zinc converters help to cope with rusty deposits and protect the metal surface from corrosion for a long time.

The active action of the reagent is explained by its complex composition, in which the zinc component plays an important role.

In order to successfully select and apply a converter, it is necessary to objectively compare analogs and not violate the technology when cleaning the product.

From this article, you will learn what a zinc rust converter is, how the agent works, how to use it, what are the consumer reviews.

What is it, how does it work?

Zinc rust converters are specially developed agents that contain in their formula not only substances that react with iron oxides, but also zinc salts.

The role of the former can be played by acids (for example, orthophosphoric)... Under the action of active components, zinc enters into a chemical reaction with oxygen and transforms into an insoluble inert compound.

The action of galvanized coatings is based on the chemical nature of metals. Zinc has a higher charge than iron. This explains its greater chemical activity: it reacts faster with electrolytes.

Outwardly, the reaction product looks like a thin film covering the surface of the product... It is she who protects the metal from moisture and the new appearance of rust.

Some converters also contain manganese as additional ingredients, which enhances the protective film layer.

Galvanizing as well as mono-component converters form a loose layer on the metal surface, which must be removed. But at the same time, the zinc inhibitor forms an additional primer under it, which is absent after acidic and neutral cleaners.

How to use galvanized?

Zinc converters used for cleaning and galvanizing:

• cars,
• metal grates,
• fences,
• equipment,
• piece products.

However, for all zinc products there is a general scheme of use:

1. The thick oxide layer is cleaned mechanically.
2. Degrease the treated area.
3. The vial with the converter is shaken.
4. Apply the product to a rusty surface.
5. Withstand the time allotted according to the instructions.
6. Peel off the top loose layer to a protective film.
7. Cover the metal with a primer and putty.
8. The treated surface is painted in a suitable color.

Most converters are designed to operate at positive temperatures (from +10 to +30 degrees).

Experts recommend the use of zinc converters if rust has little or no spread. Galvanized coatings have proven to be excellent conservatives and corrosion inhibitors. therefore they are good for cleansing and ideal for prevention.

Which to choose?

The modern market for chemicals designed to protect against rust is represented by a wide range. To determine the best remedy, it is recommended to consider several points.

Another important criterion when choosing is ease of use... Converters can have:

• liquid,
• aerosol,
• gel,
• pasty consistency.

The choice should be made based on the quality, shape and area of ​​the surface to be cleaned.

If it is necessary to treat a hard-to-reach area, an aerosol helps out. Such a tool is convenient to apply if there is no possibility of direct contact with the surface.

When cleaning a horizontal surface of a large area, gels and liquids are advisable... If the rust has little spread or is localized on an inclined surface, then it is better to use a paste or gel.

Manufacturers inform about the properties of converters in the description on the package. However, for the sake of objectivity, it is recommended to take into account the reviews of consumers who have already tested the means in practice.

The converters are distinguished not only by their efficiency, ease of use, but also by their price level. The ratio "price-quality" must be optimalso that the investment pays off with the result and the duration of anti-corrosion protection.

TOP 5 best tools and reviews about them

The most popular zinc rust converters are listed below:

ASTROhim

The formula includes:

• orthophosphoric acid,
• inhibitors,
• zinc.

The film that forms after processing the product contributes to a stronger adhesion of the primer and paint to the surface.

The average price for a bottle (500 ml) is 120 rubles.Most users (85%) recommend ASTROhim for use... Low price is noted as an advantage. The effect is assessed as "excellent".

Inconvenience is caused only by a pungent smell that is felt after applying the product.

Hi-Gear

The chemical is in aerosol form... Differs in deep penetration, long-term protection, good adhesion. The converter is popular with car enthusiasts and workshop professionals.

A 255 ml bottle is estimated at an average of 600 rubles. Reviews confirm the high efficiency of Hi-Gear. The product does not damage the paint when it comes into contact with it. The formed film lasts 3-4 months.

As disadvantages, the extremely high price is noted.

Chemist

The liquid converter with phosphoric acid forms a strong, light gray protective layer. Care should be taken when processing painted surfaces, since a strong composition can corrode paint and varnish. Suitable for processing metal and ceramic products.

A 500 ml bottle costs an average of 80 rubles. A liter bottle with a spray is estimated at 200 rubles.

More than half of users (73%) recommend "Chemist" for use... The reviews indicate a good result, economical consumption, reasonable price. The disadvantages include the toxicity of the composition.

LAVR Rust remover

The liquid agent of the 10 minutes series is suitable for the treatment of highly corroded surfaces. LAVR is characterized by fast penetration into the rust layer.

The formula is composed of:

• mixtures of organic and inorganic acids,
• Nonionic surfactants,
• phosphates,
• phosphonates.

A 500 ml bottle with a trigger costs an average of 200 rubles. There is practically no criticism in the reviews. The only caveat is possible hand skin irritation if gloves are not present. The efficiency of LAVR, ease of use, adequate price, economy are unanimously recognized.

AUTOPROFI

The composition of the liquid product includes:

• Nonionic surfactants,
• orthophosphoric acid,
• butanol,
• inhibitors,
• active additives.

A bottle of AUTOPROFI (500 ml) with a spray nozzle is sold for 230 rubles. Reviews emphasize that the converter copes with the task of removing oxides. Zinc remains in the form of whitish streaks.

But AUTOPROFI falls short of the "galvanized" category... The low information content of the label is also noted as a minus: the exposure time is not indicated.

Where and for how much to buy?

Zinc converters are not a hard-to-find commodity. They are easy to find in the automotive and household markets, in large hardware stores. An even easier way to purchase a product is to order it from an online store.

The cost of one package is determined by the brand, the volume of the bottle, the price policy of the outlet... At the same time, budget is not always associated with unsatisfactory quality. The numbers on the price tags range from 80 rubles to 600.

Application Tips

Anti-corrosion agents with zinc are convenient and effective to use. But in order to eliminate possible problems and achieve an ideal result, it is advisable to remember and apply in practice the following tips:

1. Before applying galvanizing to an expensive product, it is advisable to test it.
2. Most converters require the use of gloves.
3. Processing must be carried out outdoors or in a ventilated area.
4. To stop corrosion, the entire surface must be treated.
5. The remains of the transducer and the loose layer are removed with a brush without metal lint.
6. If necessary, the metal processing with the converter is repeated.
7. For prevention purposes, after a while, the product should be galvanized again.

All the most important and useful information about rust converters can be found in this section.

Conclusion

Modern converters with zinc are an effective solution for protecting metal surfaces from oxidation. A rich assortment of galvanized coatings allows you to choose the option most suitable for a specific situation.

At the same time, in order to obtain a satisfactory result, it is important to observe the processing technology and additional recommendations for metal protection.
