The Process Of Rusting

The red brown powdery flakes on the surface of metal are not merely an eyesore but reduce its structural strength. If not reversed in time, rusting and corrosion will reduce the metal to a chunk of useless scrap. How does this actually take place?

Rust – Is the corrosion of iron and steel a common name for Iron oxide or ferrous oxide. Iron readily combines with oxygen and moisture to form this oxide. This happens even though atmospheric oxygen is not a very pure form of gas. Moisture in the air acts as a catalyst to speed up the rusting reaction.

Corrosion is an electrochemical process that involves the anode and cathode of metal along with an electrolyte. When a piece of metal starts to corrode, the electrolyte (liquid that helps electrons to move, in this case water) helps in providing oxygen to the anode of the metal. As oxygen comes in contact with the metal, electrons become free. When they float through the electrolyte to the cathode, the metal of the anode becomes thinner, swept away by the electrical flow or conversion into metal cations in the form of rust.

The oxide of a metal is weaker in comparison to pure metal - this explains why rusted metal becomes useless in a short period of time. Use of a safe and effective rust and corrosion inhibitor goes a long way in keeping metal rust free.

Why Should You Go For Rust Inhibitors That Are Developed Using Patented Technologies?

Rusting occurs as a result of the reaction between metals and environmental elements. Metals such as iron and steel have high tensile strength and are used in many industries like marine, automotives and construction. Rusting leads to degradation of the metal, which in turn can lead to severe consequences like malfunctioning of machines and even accidents. Rust inhibitors are products that help in rust prevention and protection. Any product that comes with a certification from a respectable organization can be trusted as a quality product. When a government recognized organization awards certifications such as patents to a company, it takes into account all the aspects pertaining to quality and efficacy. 

Before making your choice for rust protection products do consider the position and status of the brand in the market. Several companies will promote their products as the ‘best’ but the word ‘best’ should be reserved for those products that fulfil all the parameters of a good rust inhibitor and are created using patented technologies.

The Need For Special Rust Prevention Solutions For Marine Environments

Rusting is a common phenomenon, but with marine environments, this problem is intensified. Salt water plays havoc by acting as catalysts to the process of corrosion. Therefore, the need of the hour is rust prevention methods that successfully remove rust and prevent the phenomenon of rusting. Methods for rust prevention include galvanizing, powder coating and use of rust resistant alloys. Galvanization is the process of coating a metal with another metal like zinc or cadmium. The major disadvantage of galvanization is the inability of the method to provide long term rust prevention. After a period of time cracks and chips begin to develop, especially in seams and joints. Painting and coating with anti-rust products help in rust prevention by establishing a barrier which protects the metal from the environmental elements that cause corrosion. Rust resistant alloys are not strong enough to withstand pressure and thus find limited use.

Rust inhibitors are chemically produced substances that provide effective rust prevention for a long period of time. Most rust inhibitors contain high levels of VOC (Volatile organic compounds) which are toxic and harm the environment.

How To Identify A Good Rust Inhibitor

Rust or corrosion inhibitors are products which are especially developed to address the problem of rusting. All rust inhibitors work differently. Their ability to prevent the process of corrosion depends largely on the method and core ingredients present in them. Certain Rust Corrosion inhibitors contain large amounts of toxic and environmentally degrading compounds like lead, acids, and heavy metals, and are harmful to use. It is important to use rust inhibitors that are free of such compounds and are VOC (Volatile Organic Compound) compliant.

A good rust inhibitor will guarantee long term protection from corrosion. Another distinguishing feature of good rust inhibitors is that they do not require extensive surface preparation. Most rust inhibitors will require you to apply additional products for UV protection, however, with a good rust inhibitor the need for additional products for UV protection and etching primers over. A good rust inhibitor should be versatile i.e. it should be able to provide rust protection to different metals. Furthermore, it should be able to protect the material from harsh climatic conditions and chemicals.

Importance of Rust Inhibitors

Rusting or corrosion of metals occurs when moisture is present in the air and reacts with the metal surface to form metal oxides, commonly known as rust. Rusting or corrosion leads to the degradation of the metal. Metals especially iron and steel are used for building boilers, aircrafts, automobiles, ships and for a whole lot of other purposes, because of their high tensile strength. Corrosion of metals leads to the breakdown of the structural integrity of the machines and equipment, and this may cause hazards in the long run. Since, no other material has been invented or discovered that is stronger and resistant to corrosion when compared to the commonly used metals, the need for good quality rust inhibitors becomes crucial.

Traditional methods like coating metals with oil or grease, applying paint, electroplating and galvanizing help prevent corrosion but fail as long term solutions. Thus, conventional methods of preventing corrosion are not very reliable. Rust or corrosion inhibitors are compounds which greatly reduce the rate of corrosion. A good rust inhibitor should have characteristics like smooth finish, ability to provide protection from chemical attacks and should do away with the need for time consuming surface preparation.

Eliminating Rust from Metals

Metals that have iron (ferrous) rust when they are exposed to water and air. Chemically, rust is iron oxide and it takes the form of a red brown powder, visible on metal surfaces. Metals that do not contain iron are also vulnerable to oxidation and this process is referred to as corrosion. To ensure the longevity of metals, it is important to prevent rust and corrosion. Timely elimination of rust and shielding the metal against this oxidation process is possible when you use a good rust removing solution.

The conventional way to eliminate rust and prevent it in future is to sand blast or scrape down the damage on surface to bare metal, prime it with a rust-inhibiting primer and then apply multiple coats of paint. But the effects of this technique are not very long lasting. A brush on liquid rust inhibitor proves to be a simpler and more practical solution for fighting rust and preventing it in future.

An ideal brush on rust inhibitor is environment friendly and does not contain materials such as lead, zinc, chromates, acids and/or heavy metals. Being in liquid form, it can also be applied by a roller or spray equipment.

Rust Free Metals

Rusting is truly a nuisance for metals. This electrochemical process converts a metal to its oxide whenever it comes in contact with oxygen in the presence of water or moisture. Parts of your car are prone to rusting even in the protective custody of a garage. But certainly you cannot let this lethal enemy of metals affect your precious vehicle. The chemical process that begins by creating ugly red brown powdery flakes on the surface of your car (or any of its metal parts) does create a lot of damage. If not checked on time, it reduces strong metals like iron and steel to weak and useless scraps. What you need therefore is a strong and effective rust inhibitor – a solution that can be practically used to eliminate all rust and prevent corrosion of the treated metal for a long time.

Powder coating and other industrial processes for rust removal are complex and very elaborate – these cannot be used by amateurs who seek an easy and handy solution for rust prevention. An easy to apply brush on or spray on rust inhibitor is the right choice in such a scenario. The inhibitor must form a protective barrier over the metal and keep it rust free and corrosion resistant while also giving a smooth and glossy finish. This is exactly what Rust Bullet does for metals.
