Anti Corrosion Spray

Protect metal with anti corrosion spray

Metal or thermal spraying is a technology, which protects and greatly extends the life of a wide variety of products in the most hostile environments. Anti corrosion spray works great in situations where coatings are vital for longevity. The variety of metallised coatings is vast but can be broken down into two main categories.

  • Finishing coatings, such as anti-corrosion or decorative coatings;  
  • Engineering coating, such as wear resistant and thermal barrier coatings.

Metal spraying is carried out in a wide range of anti corrosion and engineering markets, including oil and gas, construction, petrochemical and marine.

Corrosion is a major problem for these industries.

There are four commonly used processes in thermal spraying. But only two of these, flamespray and arcspray are normally used for finishing coatings:

  • Flamespray;
  • Arcspray;
  • Plasma Spray;
  • High Velocity Oxygen Fuel (HVOF);
  • Anti corrosion spray for motorcycle.

Anti corrosive spray applications and finishes

An anti corrosive spray is a corrosion protectant that can last up to a year. It’s also a microscopic coating that remains fluid and penetrates into fasteners. Furthermore, it kills existing corrosion next to neutralising road salt; it’s ideal for electrical connections and it even brings up matt black paint finishes and unpainted plastics beautifully.

It’s designed for the aviation market – somewhere that corrosion can be a far more serious issue than on bikes. It comes in an aerosol can (for approximately £15), or in a 950ml bottle with a handy spray dispenser (for £30). The aerosol is 95% product, so there’s little wasted space for propellant.

Anti corrosive spray on motorcycles

Spray it on with a paint gun and compressor, misting it under the tank and in all the nooks and crannies. The spray transforms the look of unpainted plastic and matt-finish metal, such as brake calipers. You can wipe it in with a cloth. However the anti-corrosion performance matters most. If sprayed into the hidden areas of your bike it will undoubtedly offer protection for up to a year or more, but the more exposed areas that are getting constant abuse from rain and salt will need spraying again. Being petroleum-based, the spray is not suitable for use on natural rubber (it can cause it to swell). You could treat it with a silicone spray first. A spray is easy and quick to use, and even if you ride every day and top it up every couple of weeks, you’ll get several months out of one can.

Other corrosion resistant coating spray applications

There are many methods for applying corrosion resistant coatings. The choice of application method is dependent on the type of coating and purpose of coating. That is why the coating process is different for decorative and industrial applications. Both, however, include cleaning and priming the surface, applying the coating and letting it dry.

Anti corrosion coating for carAnti rust coating spray for car

Cars and motorcycles are the most popular means to travel in the UK. Because vehicles consist of aluminium, steel and other metal parts, the materials corrode easily. These vehicles are made for travelling and most of the time they are on the road and object to all weather conditions. Additionally, the parts under the hood are objects to high temperatures and the bottom of the car is often in touch with water and dirt (and salt in the winters). Therefore, there are many types of anti corrosion coating for car.

Applying anti-corrosion coating increases the durability of cars and other vehicles and for example prevents leaks in the exhaust. The regular automotive paint applied during the production has anti corrosive properties but unfortunately it can wear off. Therefore, there are several rust proof vehicle refinishes on the market. In the UK, for example a rust paint called “Rust Bullet” is very popular. It is available for consumers and for industrial use also for other uses than cars. What makes Rust Bullet special is the fact that applications on already rusty surfaces are possible.

Anti rust spray for bikes

An anti corrosion spray can be described as an ultra thin fluid film compound which must be applied to a bike on an annual basis. The spray actively penetrates through the corrosion deposits to the base of the cell where it emulsifies and encapsulates the electrolyte, lifting it away from the metal surface. Then the coating dispels this moisture and provides an atmospheric barrier which prevents any further moisture contact, thereby keeping the cell inactive. Also, the compound continues to actively penetrate and “creep” into the tightest of seams, lap joints, micro cracks and around rivet heads, dissipating the moisture, even salt water, in these corrosion prone areas.

Anti rust spray in general

All methods of thermal spraying involve the projection of small molten particles onto a prepared surface where they adhere and form a continuous coating. To create the molten particles, a heat source, a spray material and an atomisation/projection method are required. Upon contact, the particles flatten onto the surface, freeze and mechanically bond, firstly onto the roughened substrate and then onto each other as the coating thickness is increased. As the heat energy in the molten particles is small relative to the size of the sprayed component, the process imparts very little heat to the substrate. As the temperature increase of the coated parts is minimal, heat distortion is not normally experienced. This is a major advantage over hot-dipped galvanising.

Arcspray process

In the Arcspray process, two electrically charged wires are driven and guided. That way they converge at a point and form an arc. An air nozzle atomises the molten metal produced and projects it towards the work piece. The driving of the wires is typically either by air motor or electric motor and gearbox arrangement. The wires can be driven in three different ways, all which offer individual benefits.
Push only, where the wire is pushed from a drive unit to the pistol. Pull only, where the wire is pulled by a drive unit mounted in the pistol. Push/Pull, this method is obviously a combination of these two methods. The wire is driven to and pulled from the pistol. These wires can typically be dispensed from portable MIG reels, coils or production packs (drums) depending on the application requirements.

Most anti corrosive sprays have the following features:

  • Permanent protection against rust and corrosion;
  • Also excellent adhesion to iron and steel;
  • Resistant to weathering, UV radiation,moisture, heat up to 500°C, alkaline solutions and mineral oils;
  • Lasting protection against rust;
  • Corrosion protection;
  • Also protection even on damaged surfaces;
  • Ideal as a protective covering and primer for exposed metal construction.
