powder coating automotive parts makes beautiful and durable finishes

Versatile durability for the complete vehicle by powder coating automotive parts

A vehicle presents a wide range of substrates to be protected and decorated with coatings. From bodywork and bumpers to wheels and suspension components, powder coating automotive parts is becoming more and more the go-to solution for the industry. It is durable, efficient, environmentally friendly, and attractive. Increasingly the coating industry is turning to greener and more efficient coatings as regulations and attitudes change. Automotive powder coating can be OEM-applied or refinish, with the vast share of the market being OEM coatings.

In this article we take a close look at automotive powder coating, both OEM-applied and refinish, and its various benefits and applications. We also take a look at the companies leading the industry of powder coating automotive parts in Qatar.

Why powder coating automotive parts beats liquid coatings

Powder coating is a coating process where paint is applied to a substrate in the form of a dry powder which cures through baking. Baking causes the dry powder to melt and flow, forming bonds with the substrate and crosslinking to create a hard and resilient barrier. Coating a vehicle is a complex process. With many different substrates with different needs, a vehicle requires a variety of specially formulated coatings in order to perform at its best for the longest possible time. The automotive industry still predominantly relies on liquid paints for its coatings, although changing regulations and more efficient coatings are having some effect.

Powder coating automotive parts is efficient and allows for color variety.

Three of the reasons for using a powder coat rather than a liquid paint are:

  1. PERFORMANCE: Powder coatings are durable and more resistant to corrosion, scratches, abrasion, and damage than liquid paint. They also have excellent color retention, gloss retention, and do not run or drip.
  2. ENVIRONMENTALLY FRIENDLY: Unlike liquid paints, powder coating emits zero or near-zero VOCs, and, because overspray can be collected and recycled, no hazardous wastes. It is also solvent-free.
  3. EFFICIENT: Single coat applications, thin or thick film applications, a fast cure time, and lower material and operational costs are all benefits to powder coating.

The process of powder coating automotive parts and surfaces

Currently, the OEM and refinish markets for powder coating automotive parts focus on specific areas. In these areas powder coating is chosen for its powerful durability and toughness. There are both interior and exterior applications for automotive powder coating:

  • OEM PRIMER & CLEAR COAT: As a metal substrate that is exposed to all the elements, corrosion is serious concern for vehicles. As well as a corrosion resistant e-coat, a powder coat primer layer is applied which provides stone chip protection and prevents damage from breaking through to the bare substrate. The final clear coat can also be powder, using the chemical resistant, weather resistant, and UV stable properties to seal and protect the underlying layers.
  • HEAT RESISTANT POWDERS: There are plenty of substrates on a vehicle that are exposed to high heat. To protect these substrates from possible damage, the can be coated with heat-resistant powder coating. The powders are usually epoxy and silicone-based and provide heat resistance for temperatures ranging from 200°C to 550°C. Exhausts and engine parts principally benefit from this treatment.
  • UNDERBODY PROTECTIVE COATING: The underside of a vehicle is particularly vulnerable to damage and corrosion and it needs to withstand everything the road can throw at it. A powder coat’s corrosion resistant and tough finish protects the underbody from this.
  • AFTERMARKET COATING: A large section of the consumer market for powder coating automotive parts and surfaces is aftermarket refinish. Wheels, grilles, carburetor parts, engine casings,  radiators, and plenty more aesthetic details can be powder coated in specialty garages and shops.

The increasing demand for automotive powder coating

Automotive coatings is a big industry, and many manufacturers and companies are active in Qatar. AkzoNobel’s powder coating brand Interpon manufacture a product series designed especially for wheel manufactures, called Interpon A4000. Axalta produces powder coatings for transportation through their brand Alesta. This includes bodywork, interior plastic coating and special coatings for commercial vehicles, buses, and trains. PPG is another big name in powder coating automotive parts, with OEM automotive and transportation coatings. The top five automotive refinish coatings companies are Axalta Coatings (Cromax, Spies Hecker, and Standox), AkzoNobel (Sikkens, Dynacoat, and Wanda), BASF (Glasurit, LIMCO), PPG Industries, and Sherwin-Williams.

The powder coating industry is driving innovation in automotive coatings, chiefly as a greener, lower-carbon footprint, more cost efficient alternative to liquid paint. AkzoNobel and Citroën recently partnered in producing the first ever full body monocoat powder coating to be used on a passenger vehicle in Europe. The matt black textured coating is still in design stages, but the face of automotive powder coating is changing.
