Why the Automotive sector needs protective coatings?
In the automotive industry, durability and aesthetics are equally important. Components must endure constant exposure to road conditions, temperature changes, and environmental factors while maintaining a flawless, professional finish.
With projects ranging from vehicle trailers to small complex components, it is imperative that we understand the required level of protection that your item needs. ISO 12944 is a good place to start when determining what level of protection you require. You should also think about the thickness of the item, substrate and location where it will be going as these can all influence what the recommended coating specification is.
At Northpoint, we deliver sustainable advanced protective coating for automotives tailored to the specific demands of the automotive sector, ensuring superior protection, longevity, and visual appeal for vehicles and parts.
Our protective coating for automotives process ensures that components not only look exceptional but also withstand the rigors of everyday use and environmental exposure. Whether for functional parts, decorative trim, or high-performance systems, we deliver coatings that meet the demands of the industry.
Working to a number of specifications, we are happy to discuss your project requirements and advise on a suitable solution through the support of our trusted paint and powder suppliers.
| ISO 12944-2 Tab. 1 – Categories of Corrosion | |
| Category of corrosion | |
| C1 – Very Low | Very little or no pollution. Heated buildings, offices, shops, schools, hotels etc. |
| C2 – Low | Low levels of pollution. Mostly rural areas. |
| C3 – Medium | Urban and industrial areas, moderate sulphur dioxide pollution. Coastal areas with low salinity [not under direct influence of salty air/wind] |
| C4 – High | Industrial areas and coastal areas with moderate salinity. Sea front areas |
| C5 – I Very High | Industrial areas with high levels of humidity (Middle East) |
| C5 – M Very High | Coastal and offshore areas with high salinity. Sea front protection barriers, oil rigs. |
| CX – Very High | Marine and offshore environments. |
Process Northpoint would go through to coat
Our specialised coating process is designed to meet the high standards of the automotive industry, providing protection and performance for every component.
Here’s how we achieve exceptional powder coating results:
1. Surface Preparation
Each automotive part undergoes thorough cleaning and pre-treatment to remove contaminants, such as grease, dirt, and previous coatings. This step ensures strong adhesion and prepares the surface for a flawless finish.
2. Masking and Inspection:
Areas requiring protection from coating are carefully masked, ensuring precise application. Every part is inspected to confirm it meets preparation standards before proceeding.
3. Powder Application
Using advanced powder coating technologies, we apply a uniform protective layer. Our coatings are formulated to enhance resistance to corrosion, UV exposure, and wear while offering a high-quality aesthetic finish. Options include a range of colours, finishes, and textures to match automotive industry requirements.
4. Curing
The coated parts are cured in high-temperature ovens, solidifying the coating into a durable layer that provides excellent resistance to chipping, scratching, and environmental wear.
5. Quality Assurance
Each item is rigorously inspected to ensure even coverage, proper adhesion, and compliance with automotive industry standards for both functionality and appearance.
6. Delivery
After passing our stringent quality control checks, parts are securely packaged to protect the finish during transport.
Our coating process ensures that automotive components not only look exceptional but also withstand the rigors of everyday use and environmental exposure. Whether for functional parts, decorative trim, or high-performance systems, we deliver coatings that meet the demands of the sector.
Frequently Asked Questions
Common questions about protective coatings for the automotive sector. Cannot see what you need? Call +44 (0)161 330 4551.
What automotive components can Northpoint powder coat?
We coat everything from large vehicle trailers and sheet metal fabrications to small, complex automotive components, decorative trim and high-performance functional parts. Our process handles both intricate geometries and larger steel assemblies.
How do you decide the right coating specification for automotive parts?
We specify against ISO 12944 corrosion categories (C1 to CX), taking into account substrate thickness, the part's operating location and environmental exposure such as road salt, UV and abrasion — alongside your own requirements. We listen closely to each customer's brief, including any specification or testing documentation provided by the end customer, so the finished coating meets both the technical and commercial requirements of the job.
Will the coating resist corrosion and wear in service?
Yes. Our advanced powder formulations are engineered for UV resistance, corrosion resistance and wear protection, and every coating carries a guaranteed life expectancy. As an experienced coating specialist, we match the durability to the demands of automotive use.
Can you match specific colours, finishes and textures?
We offer a wide range of colours, finishes and textures so parts meet both functional and styling requirements. Send us your RAL reference or a sample and we'll confirm availability before coating.
