Automotive coating Qatar

Automotive coating – factory applied looks and protection

The automotive coating industry is far larger than which color to paint your car. Every surface in a vehicle from the bodywork and under body to the exhaust and even the glass surfaces needs a specialized coating to last and perform its best. The automotive coatings market can be roughly divided into OEM automotive coatings and aftermarket and refinish coatings – basically those applied at manufacture, and those applied after. The umbrella term “automotive coating” covers all the coating varieties within those categories.

In this article we will look into the Qatari automotive market and coating demand, outline the different types of automotive coatings and provide you with more detailed information on the different coatings in the articles you can find by opening the links on this page.

An introduction to OEM automotive coating

When stripped down to bare bones, a vehicle is a collection of different substrates from different materials, each with their own needs and demands in terms of coating. The bodywork alone receives five different coatings before it is ready for a shop. Worldwide the top OEM automotive coatings manufacturers are PPG, BASF, and Axalta. Here we will give a brief overview of the coating processes that go into making a vehicle.

The paint shop – from pretreatment to final coat

When the bare metal body of a vehicle hits the paint shop, it is in for an intensive 12-14 hours. Coatings are applied one after another in a series of processes carefully calculated to provide both the best coat for the substrate and the best result for the following coating. In order these steps are:

1. Phosphating – This first step or pretreatment involves applying phosphoric acid to the substrate in order to cause a reaction which makes the substrate easier to adhere to. It also gives a degree of corrosion protection to the substrate.
2. Cathodic electrocoating – The combination of the e-coat and the phosphating is the part of the coating system that gives the substrate its corrosion resistance. In this step the substrate is immersed into a paint in an aqueous suspension (dispersion), usually an epoxy-polyurethane. When an electrical current is applied the paint adheres to the substrate and forms a consistent layer of corrosion protection, even in difficult-to-reach cavities.
3. Primer coat – This coat evens out any irregularities of the electrocoat and is particularly important for stone chip resistance to protect the underlying layers and the metal from damage and resulting corrosion. Primers come in solvent-based, water-based, and powder forms, and are most commonly polyurethane-modified polyesters and epoxy resins.
4. Base coat – The base coat and clear coat combined make up the top coat layers. The top coats give color and durability to the coating system. The base coat gives the main color to the vehicle, which can come in solid color, metallic, pearlescent, matt, and other special effect paints.
5. Clear coat – The clear coat protects the top coat and pigments from the environment, scratches, chemical attack, UV radiation (especially important in Qatar). They seal the coating system and provide the first line of defence as well as the smooth, glossy final appearance. Clear coats come as one component, two component, or powder, though they are predominantly liquid. Common coating types for a clear coat are acrylics and polyurethanes.

2. Underbody paint – protection to parts out of sight

Out of sight is often out of mind, and problems can arise when the underbody is underprepared for the harsh conditions it will face. Underbody paint protects a vehicle’s chassis from corrosion and damage caused by everything the road throws at it. They are applied over the electrocoat and must have extreme mechanical and chemical resistance. Underbody paints:

• Protect from stone chip damage – By forming a tough, flexible, rubbery protective film, underbody paint provides a barrier between the substrate and stone chips, gravel, road debris, sand, and other objects which may damage it.
• Extend service life – Protecting a significant section of a vehicle from damage and rust extends its life while maintaining its value.
• Improve driving comfort – Reduces sound and vibration from the road and makes the driving experience more pleasant.
• Protect from weather conditions and environment – The coating prevents water ingress (whether standing water or rain), as well as exposure to snow, baking heat, salt from winter anti freeze measures, and salt from coastal weather and roads.

An underbody protection coating is applied by spray or brush, and they come in a variety of formulations. These include one and two component polyurethanes, bitumen paint, and wax coating.

3. Powder and plastic coating for the small but many parts

Powder automotive coating is commonly applied on wheels.

Wheel, front grill, drive shaft, brake parts, suspension springs, interior and exterior trim, door handles, climate control bezels, speedometer housings – the list of automotive parts that need coatings beyond the bodywork is seemingly endless. A popular option for under-the-hood car parts is extremely durable powder coating, while internal coatings are often polyurethanes. These provide a soft-feel coating for those surfaces most often touched, in one and two components and a range of colors and effects.

4. Special commercial vehicle paints

Commercial vehicles are those intended for multi-passenger or goods transport, such as vans, coaches, buses, trucks, and semis. They spend a lot of time on the road, and the automotive paint needs to be able to endure this. Durability is key, as well as corrosion, UV, and chemical resistance. Fleet owners look at the conditions their assets will be exposed to and the intended service life of the asset in order to determine which coatings they need. A range of colors and the ability to easily repair damage are also highly important for commercial vehicle coatings to reduce vehicle off road time and inconvenience.

Aftermarket automotive paint for refinishing and repairing

The aftermarket automotive coating industry covers custom finishes, collision repair, and commercial fleet finishes among other coatings applied to a vehicle once it has left the shop. The top 5 automotive refinish coatings vendors are Axalta, AkzoNobel, BASF, PPG, and Sherwin-Williams. In Qatar, the automotive market is shifting to focus on aftermarket products due to the fact that the demand is moving towards upgrading vehicles.

• Collision repair paints and refinishes – Accidents happen. Whether through a collision or scratches to the bodywork, paint can be damaged. Or maybe you want to give your car a spruce. Car repair paints and refinishes represent a large sector of the industry. They differ from OEM paints because their application has different requirements, including a lower heat curing and longer drying times. If you need a commercial fleet fitted out with logos or livery, you will likely use a refinisher.
• Powder coating – A key refinishing market is the powder coating market. Everything from wheels and valve covers to shock absorbers and bumpers can be powder coated. For those who want a unique and hard-working paint, powder coating is the popular choice.
• Ceramic car coating – This is a type of paint protection coating which uses nanotechnology to protect a vehicle’s paintwork from damage from UV radiation, as well as maintaining its gloss and repelling dirt and water. It is an alternative to regular waxing and provides up to several years of protection if properly maintained.
