Segmentation by Application

Applications define the true value of automotive exterior and interior coatings. Each sector leverages the coatings’ unique properties—durability, aesthetics, and environmental resistance—to address specific vehicle protection needs.

1. Clearcoats

The clearcoat layer provides a protective top finish, enhancing gloss and shielding against UV damage, scratches, and chemicals. It is essential for maintaining the vibrant appearance of vehicle exteriors over time.

• Insight: Clearcoats dominate the application segment, accounting for a significant portion of exterior coatings due to their role in premium finishes and long-term protection in passenger vehicles.

• Trend: Advances in self-healing clearcoats are emerging, particularly for electric vehicles where thermal stability is crucial, driven by rising global demand for durable aesthetics.

2. Basecoats

Basecoats deliver the color and visual effects, forming the foundation for the clearcoat. They incorporate pigments and metallic flakes for customized appearances in both exterior and interior components.

• Insight: Basecoats are key in customization trends, with growing use in interior trims for personalized cabin environments, supported by OEMs’ focus on consumer preferences.

• Trend: Shift toward water-based basecoats in Asia-Pacific manufacturing hubs reflects regulatory compliance and cost efficiencies in high-volume production.

3. Primers

Primers ensure adhesion between the substrate and topcoats, providing corrosion resistance and surface preparation. They are vital for underbody and chassis applications in harsh conditions.

• Insight: Primers see steady demand in commercial vehicles, where corrosion protection is paramount, contributing to overall vehicle longevity in fleet operations.

• Trend: Eco-friendly primer formulations are gaining adoption in Europe, aligning with sustainability goals and reducing application times in automated lines.

4. Electrocoats

Electrocoats apply an electrophoretic layer for uniform corrosion protection on metal parts, commonly used in body-in-white stages of vehicle assembly.

• Insight: Electrocoats are indispensable in OEM production for their efficiency and coverage, particularly in electric vehicle frames requiring enhanced electrical insulation.

• Trend: Improvements in cathodic electrocoats are boosting penetration in emerging markets, where vehicle production is ramping up rapidly.

5. Interior Coatings

Interior coatings focus on soft-touch finishes, antimicrobial properties, and wear resistance for dashboards, seats, and trims, enhancing user experience and hygiene.

• Insight: This segment is expanding with shared mobility and EVs, where antimicrobial interiors address health concerns and improve cabin durability.

• Trend: Premium textures and low-VOC interiors are trending in luxury segments, driven by consumer demand for sustainable and comfortable vehicle environments.
