VD-40 - what is it? Universal aerosol grease WD-40: characteristics, application, manufacturer, reviews
On the shelves of automotive stores you can find a large number of lubricants. There are compounds for joints, bearings, brake pad guides and many, many other products. But today we will consider the universal grease VD-40. This is almost everyone who owns a car. Should I buy it and what can I do with it? Read more about the advantages and features of VD-40 in our today's article.
VD-40 is a universal lubricant. It was developed in the USA in 1958. Initially, the manufacturer WD-40 did not plan to use it in the automotive industry. This product was developed by order of Convair to protect Atlas missiles from rust.
Now lubricant is produced mainly in the automotive field. It is produced in the form of a metal spray can with an extension tube (thanks to it, you can easily get to hard-to-reach places). The volume of fluid is different, but often amounts to 100, 200 and 420 milliliters.
What is included in the composition?
The complete composition of this lubricant is a trade secret. However, European experts have already studied the chemical composition of VD-40. So, this product consists of:
- White spirit. Its concentration is about 50 percent.
- Nitrogen dioxide. She is filled with a quarter of the American product.
- Mineral oil. Its share is 15 percent.
- Additional additives VD-40. What it is? These additives include silicone, wax, kerosene, graphite, as well as other chemicals.
At the moment, this lubricant is used in almost every workshop. There is a VD-40 and many motorists. Especially often it is used by those who make car repairs with their own hands. According to reviews, VD-40 copes with rust. This makes it easier to loosen the oxidized nuts.
Studies have shown that the average turning point for bolts of 12 millimeters without pre-treatment WD-40 was 11 kgf / m.After the “deacidification”, the bolts were unscrewed with a much smaller force - 8.3 kgf / m. You can also use the product as protection against freezing of door seals. Thanks to the oil that is in the composition of VD-40, the doors will not freeze after washing in cold weather.
But it is better to use silicone grease in this regard - say reviews. In addition, it costs much less than the American VD-shki.
VD-40 grease is not a panacea for all "diseases." You should not use it in different areas. Among the features of the composition is worth noting its hygroscopicity. As practice has shown, this lubricant is able to attract and absorb moisture after a while. For long-term corrosion protection, VD-40 is not suitable. Also, you can not use the composition as a lubricant. Such a connection will not be well unscrewed in the future, because the liquid evaporates quickly (during the day). Another "underwater stone" concerns rubber products. Do not splash on the nozzles and hoses VD-40. Product characteristics can change the elasticity of rubber. It will become hard and begin to crack.
Thus, VD-40 (we already know what it is) only shows itself well in the field of auto repair. The main purpose of lubrication is to provide easier unscrewing of threaded connections.And for long-term processing experts advise the use of other, more dense and dense formulations. These are “grafitka”, “Litol-24” and “Solidol” (and they are much cheaper).
Use in life VD-40
Oddly enough, but some use this lubricant in the household. Where can I use in everyday life universal automotive grease VD-40? This compound perfectly removes glue and grease stains (as for cars, the product cleans and bituminous stains). Also, the spray is great at removing chewing gum from clothes and hair. Well removes VD-40 rust on the surface of pipes in the bathroom. But in advanced cases, it is better to use a rust converter. VD-40 acts only superficially.
Perfectly eliminates American product and traces of fat. This is not surprising, because half of the composition of VD-40 is white spirit (a powerful chemical solvent). It is also used as a water-repellent impregnation for boots and other shoes. But this protection does not last long - say reviews. And it must be borne in mind that not every material VD-40 will work effectively. Therefore, first it is better to apply on a small area and test the protection.Another VD helps with freezing windows. And some even use a lubricant like dichlorvos against cockroaches and other harmful insects.
Using this lubricant, you need to remember what it is. VD-40 is a flammable liquid that emits acrid vapors. It should not be allowed to fall on his hands, and especially in the eyes. It is necessary to work in rubber gloves, and if liquid gets on the body, do not hesitate to rinse. If possible, do not breathe in pairs of lubricant, as in the composition there is an aggressive white spirit.
It is worth noting that the VD-40 - the most expensive of the universal lubricants that exist on the market. Therefore, many motorists are trying to find a way out by purchasing cheaper counterparts. Among these it is worth noting:
- "Likvi Moli LM-40." This product is manufactured in Germany. The lubricant is available in the form of the same spray with a plastic tube. "LIQUI Moli LM-40" is designed to protect the electrical system of cars, displace moisture and eliminate corrosion. According to reviews, the product has no unpleasant smell. Spray is characterized by vanilla flavor. During the tests, the German product also showed itself well.After deoxidation, the nut is unscrewed with a torque of 2 kgf / m lower than before the application of the agent. Among the shortcomings of the product reviews indicate unsuccessful tube-spout attachment. It is very easy to lose. But in general, “Likvi Moli LM-40” is an excellent analogue of VD-shki, which can be used not only in the garage, but also at home.
- "Liquid Key". This composition is produced by CJSC “Elf Filling” in Russia. It is 30 percent cheaper than the German product. The manufacturer positions it as a universal tool for unscrewing rusted parts. The composition is able to return the former mobility of threaded connections. Also suitable for eliminating squeak in the loops. In everyday life, it is used to combat jamming locks. Also, the Russian "Liquid Key" perfectly displaces moisture and can be used as a means to protect electrical wiring. The volume of the bottle - 335 milliliters. Also included is a plastic spout that is mounted on a convenient elastic band. However, there is a "key" and disadvantages. It is a sharp and unpleasant smell. Therefore, it is often impossible to use such a tool in a residential area. Also, the tool is badly struggling with seriously corroded bolts.During testing, the moment of unscrewing the nut decreased by only one kilogram.
So, we found out the features of the product VD-40. What it is? This is a universal grease. Where to use this product? Its main area of application is still cars. The product copes with rusty nuts and bolts. But due to the high cost it is difficult to apply in any other area.
It is unprofitable to buy a lubricant to protect the footwear - it is easier to use specialized means for this. Also, the grease does not provide long-term protection against corrosion. And as a rust converter, it is no good. Therefore, no matter how they talked about all sorts of applications, the VD-40 was and still is only suitable for loosening soured nuts.
