How to choose a rust converter

The problem of choosing rust converters entirely goes back to the problem of lack of knowledge about the mechanism of work. IN in most cases, people who decide to buy such a tool rely on on existing experience, or rely on their own luck. In view of This project provides you with a clear guide to choosing and recommends paying attention to the following aspects:

  1. The main active substance. Those in the converters two rusts: acids or active zinc ions. The first are intended for urgent elimination of corrosion with maximum impact on the outbreak its occurrence. The result of such exposure is usually salt coating, which is easily washed with a dry rag. Zinc-based converters, in turn, provide metal tread, simultaneously destroying rust on its surface. According to the results of application at the treatment site thin zinc film protecting the metal from negative factors the environment. The disadvantage of this tool: possibly incomplete impact on the center of rust, which, when galvanizing, begins redevelop.
  2. Consistency. Another important parameter rust converters is consistency. It depends on her how the possibility of penetration into areas with deep corrosion, and the method application. Aerosol formulations have a higher absorption, can penetrate into inaccessible places, but significantly inferior competitors in focusing on a specific location. In contrast, pasty transducers are used mainly in easily accessible places, do not have high penetrating but provide a more serious local protection, often used instead of a primer. Currently on gel converters have appeared on the market, combining the advantages the first two consistencies, but their cost is slightly higher.
  3. Security level. Despite the fact that absolutely everything rust converters are dangerous for skin, mucous membranes integument and respiratory tract of a person, until recently, all of them belonged to the number of explosive. Today there is a large number of alternatives that do not contain combustible substances, but have a similar mechanism of action effectiveness. If possible, give preference to such compositions.

Best Rust Spray Converters

Liqui Moly “Pro-Line Schnell-Rostloser”

Rating: 4.9

Liqui Moly

Rust converter Liqui Moly “Pro-Line Schnell-Rostloser” – a tool that is magnificent in all connected senses. Despite the high cost (which is the only drawback) is different delicate and directed action on the zone of damage to the metal corrosion, allowing complete processing in a matter of minutes.

The mechanism of action of this solution combines the principles WD-40 and our usual modifier: neutralizing rust, it cleans moving joints (and makes it possible to unwind them), and with subsequent washing forms a protective film on the surface. The latter is the result of the action of filler materials in which zinc ions also enter. Liqui Moly “Pro-Line Schnell-Rostloser”neutral to paint, and therefore does not represent for her any the slightest danger. You can apply it even on contaminated surfaces – excellent penetration and will cope with rust and dirt. In general, among other things being equal this converter stands out in an advantageous way, thanks to which takes a well-deserved first place.

Advantages

  • neutral to paint, soil;
  • high penetrating effect;
  • a complex of additives provides lubrication of moving parts, and also wedges them (like WD-40);
  • 400 milliliters of volume;
  • creating a durable film on the metal surface.

disadvantages

  • high price.

Hi gear

Rating: 4.8

Hi-Gear

Expensive and very effective composition from a foreign company Hi-Gear, whose main advantage is directional and fast action even on deep foci of corrosion. Powerful factory cylinder atomizer provides a jet outlet under significant pressure, making the already magnificent the penetrating ability of the modifier increases several times. The increased content of active active substance, which this case is phosphoric acid, has instant destructive effect on iron oxides, turning them into high hardness polymeric compounds.

True, for such a transformation, Hi-Gear must be washed off alcohol – water will not provide the proper descent of so concentrated facilities. The only really serious minus of this transducer is in extreme danger to respiratory pathways, skin and mucous membrane of a person. Increased acid concentration and destructively affects the paintwork, therefore, for damage to painted surfaces is only a small drop facilities.

Advantages

  • very effective action up to the destruction of the deepest corrosion sites that are susceptible to this type of service;
  • high penetration;
  • formation of a strong film when reacting with oxides gland;
  • low consumption.

disadvantages

  • poses a danger to humans and destructively affects paint;
  • high price.

Autoprofi

Rating: 4.7

Autoprofi

Autoprofi aerosol modifier differs little in efficiency from a liquid analogue (marked “Galvanized”), but still carries a few pleasant (and not so) nuances. how and before, the product is characterized by low price and huge volume spray bottle: as much as 500 milliliters. Sprayer in this trigger case, capable of operating in wide and narrow mode jets. The first, as practice shows, is no different efficiency – fine suspension is not strong enough to overcome obstacles in the form of large pieces of rust and is suitable only for sprinkling of local slightly contaminated areas. Narrow the jet, in turn, has a directed action, turning out to be punching enough to impact even deep foci rust.

Another nuance that users point out is poor adhesion of spray paint. In this regard, before painting the composition urgently needs to be completely removed from surfaces using a special wash. Otherwise there is a risk of damage to the paintwork, which is especially unpleasant when processing a car body.

Advantages

  • very low price;
  • the possibility of spraying in two modes spraying;
  • optimal vial volume (500 ml);
  • high penetration of the composition.

disadvantages

  • the need for thorough washing before further processing products;
  • poor adhesion.

The best liquid rust converters

Astrohim with active zinc ions

Rating: 4.9

Astrohim with active zinc ions

The product is manufactured by the domestic company ASTROhim, low cost liquid modifier segment rust. Clear savings are evident here: 500-milliliter cans cost a little more than 250 milliliters of the same type of aerosol, but enough of them, as a rule, for a longer period.

In general, the classical composition of the converter has a number filler materials, as well as zinc ions, which are not only create a protective film, but also tighten shallow scratches and microcracks in the material. The second active substance is phosphoric acid – has a direct effect on corrosion layer, highlighting the products of its complete neutralization. For final cleaning of metal from processing traces carefully enough wipe the surface with special napkins, then on it a thin layer of galvanization will appear. Having good adhesion, given the modifier allows you to apply a layer of paint on top, without fear for it cracking and poor hiding power. ASTROhim with zinc ions Great for sparing car body repair, as well as processing irresponsible painted elements from metal.

Advantages

  • very low price;
  • high-quality performance of the main function (removal rust);
  • quite a large amount of converter;
  • formation of a zinc film on the surface of the treated metal.

disadvantages

  • Before further processing of the metal, careful removal of funds from the surface.

Fenom

Rating: 4.8

Fenom

The next line of the rating goes to the solution from Fenom, approved by the double action on the metal. Besides anti-corrosion (quite effective at low consumption) this the converter acts as the primary means for processing the part, forming on it a stable polymer compound with high adhesion. All of the above properties contribute to more high-quality “bunch” with paint and a primer, and also guarantee the absence and development of foci of rust for the next 5-7 years.

According to consumers, the low cost of Fenom is no more than marketing fiction designed to drive consumer activity. The modifier is only available in jars of 11 milliliters, which, even with all the cost-effectiveness of the means, are not enough for normal handling of the body. This entails a purchase. several packages, which ultimately translates into good spending.

Advantages

  • double action (removal of traces of corrosion + formation protective film);
  • high adhesion with paint and primer;
  • prevalence in stores throughout Russia.

disadvantages

  • low price visibility (when calculating the required volume modifier is expensive).

The best gel rust converters

Permatex 81773

Rating: 4.9

Permatex 81773

Strong gel-type rust modifier providing reliable metal overlap after the reaction. Has accelerated mechanism of action, due to which processing takes only 2-3 minutes. Permatex 81773 forms a hard polymer coating of black colors, in fact, not very suitable for painting in brighter colors (since the machined part, if we are talking about the body car will be noticeably darker than the base).

The operating temperature range of this converter varies in area +10 – +32 degrees Celsius, while it is important that he the coated metal was not heated by more than +93 degrees. Values ​​higher than required will result in poor polymer overlap. with a primer, or they will not at all allow the composition to react normally. Permatex 81773 is packaged and distributed in banks of 454 grams each, and for application it is most advisable to use a brush. It is used mainly in agricultural machinery, with metal protection of car bodies, as well as others metal products for critical purposes.

Advantages

  • fast action mechanism (polymer coating is formed in 2-3 minutes);
  • very dense and strong resulting coating suitable for subsequent painting;
  • low consumption of the composition for processing parts.

disadvantages

  • poor adhesion at elevated temperatures.

Kudo KV-70005

Rating: 4.8

Kudo KV-70005

Gel “poultice” for processing ferrous metal before suitable for small repairs to eliminate paintwork defects. The principle of operation of Kudo KV-70005 based on the formation of a phosphate film that does not affect painted metal, affecting only the place of corrosion.

This modifier is packaged in jars of 15 milliliters, of which enough for intelligent processing on average 0.02 square meters metal. This is quite a bit, given that alternative means provide much more economical application (take the same Permatex 81773). Together with the cost (or rather, being derivative from it), this aspect is the main disadvantage facilities. However, it is worth recognizing that with its work it copes very well, especially in moments of recovery painted iron against minor defects such as scratches, cracks, micro-chips, etc.

Advantages

  • active corrosion inhibitors, reaching its focus origin;
  • the effect of “tightening” minor defects of the paintwork coverings;
  • formation of persistent phosphate film;
  • good adhesion.

disadvantages

  • high price and small volumes of packaging.
