Corrosion of a metal is a chemical process that causes many problems, because rust can appear on any metal surface. How to deal with it, and is there a good remedy for rust on metal? Let's try to understand the causes and effects.
What are the ways?
During corrosion, the surface of the metal begins to oxidize, after which it is destroyed. It is impossible not to notice these phenomena, since the surface is quickly covered with dark brown spots. You can try to deal with rust mechanically, that is, grinding the affected area using special disks or sandpaper. Of course, this is not the most effective tool against rust on the metal, and even with strong pressure, you can damage the treated area. That is why experts advise using chemical compounds that help get rid of the problem, preventing its possible occurrence in the future.
Chemical methods
The most effective way to deal with rust is to use various chemical compounds that can successfully cope even with hard-to-reach areas of the car body or other metal surface. Any remedy for rust on metal is used in a certain sequence:
- first the surface is degreased;
- it is processed with special compounds;
- the surface is washed several times;
- high-quality drying is carried out.
We use a rust converter
One of the popular special tools that can fight metal corrosion is the converter. It is a compound that converts corrosion products into a protective film that appears on the treated surface and has good strength. According to reviews, converters are quite economical and efficient. In addition, it is convenient to use them, since they are available in the form of suspensions, emulsions or solutions.
Such a rust inhibitor on metal is ideally suited for processing metal structures of any type, but there is only one condition - the rust layer should not be thicker than 100 microns. A lot of good reviews about converters, which are based on film-forming substances. In addition, they contain inhibitors, pigments, biocides, which in combination increase the protective characteristics of coatings. The application of these compounds is carried out only on a carefully prepared surface with preliminary cleaning of loose and loose upper layers of rust.
Tsinkar
A very good tool to combat rust, according to those who have encountered the problem of corrosion of the car body. Zincar is based on zinc and manganese compounds. Using this tool against rust on metal, you can create an active protective coating on the surface of the material. This drug is effective in its effect, as it has a balanced composition. According to users, “Tsinkar” easily copes with the processing of any metal surfaces from which it is necessary to remove corrosion damage and protect them from the effects of climatic factors. Among the advantages, they note the ease of working with the composition, the conversion of rust, which can later even be painted. Of the minuses, many focus on overpriced, toxicity and the need for accurate work.
Primers
It is also a popular chemical rust agent on metal. A huge amount of primers can be used to process metal surfaces. They can be phosphating, passivating, isolating, projecting and transforming. Among the compositions popular with buyers, the following can be noted:
- EVA-0112 (TU 6-10-1234-79). This primer includes orthophosphoric acid in its composition , is effective, especially if used in combination with a paintwork with epoxy resin in the composition. To improve the composition, you can add benzidine or barium carbonate to it.
- EP-0180 (TU 6-10-1658-82). This primer is ideal for use on surfaces where corrosion is uneven. As users note, when using this composition, a film forms on the surface, which can act as an independent protective coating.
- EVA-01-GISI (TU 81-05-121-79). This composition is presented on the market in a large number of modifications, each of which has a special composition. So, EVA-07-GISI is resistant to moisture and biological factors, and EVA-016-GISI has unique protective properties.
- Modifier MC-0152 consists of various fillers, pigments, solvents. This is probably the best rust remedy on metal that can be used at low temperatures. According to reviews, it is such tools that are ideal for independent use, as they are practical and versatile.
Application features
Any means that can save a metal surface from corrosion should be correctly used. To do this, you first need to thoroughly clean the surface of dust and dirt. After that, a rust transducer is applied to the surface to be treated using a brush or spray gun. Now you need to wait until it dries - at room temperature it takes a couple of hours. After complete drying, it is worth evaluating the treated area and, if necessary, reprocess it with a converter.
How to remove rust from a car?
Most often, corrosion spots occur on the car body. You can’t leave them, since the area affected by rust will only grow, and from an aesthetic point of view this is not the right decision. That is why many people are trying to save their car using a special tool against rust on metal. A car after such a treatment can even find its original form, especially if you correctly select the compositions for subsequent painting.
What means can remove traces of corrosion, we described above. The main thing is compliance with safety regulations. And it includes the use of gloves, masks and glasses, high-quality shelter of the rest of the car so that there are no traces of converters and primers on it. Of course, you can try to cope with the affected area with simple products - vinegar, soda, lemon juice, but such home methods will not save from re-oxidation.
That is why it is better to buy a special
tool for removing rust from metal, which will cope with damage more effectively. Better yet, contact specialized services, where they can do this job even better.
