The digital infrastructure boom shows no signs of slowing. As AI adoption accelerates and hyperscale computing demands grow, data center investment is surging across every part of the build, from the facilities powering machine learning workloads to the infrastructure supporting cloud and SaaS delivery at scale. This growth is putting unprecedented pressure on every component inside these facilities, and on the supply chains responsible for protecting them.
Coatings manufacturers have quietly become one of the most critical partners in this ecosystem. Far beyond simple aesthetics, advanced coating technologies now serve essential protective functions: managing extreme heat loads, preventing electrostatic discharge, stopping thermal runaway in battery systems, and ensuring fire and corrosion resistance across thousands of square feet of densely packed equipment. What was once a finishing step in construction has become a core engineering decision tied directly to uptime, safety, and compliance.
This whitepaper from PPG examines the specialized coating technologies that protect modern data centers and explores the certifications, performance categories, and application strategies that data center builders, operators, and specifiers need to understand.
You will learn:
- Why coating technologies have become essential to data center reliability and energy efficiency

- Where key sustainability metrics like PUE, WUE, and CUE intersect with coating performance
- How UL and IEEE certifications validate fire, electrical, and thermal safety for coated components
- Which coating types address the five pillars of resiliency, efficiency, safety, security, and sustainability
- Why integrated, layer-by-layer coating systems reduce complexity and improve long-term durability
- What coatings are recommended for specific components like servers, generators, transformers, and battery storage
- How EMI-shielding and dielectric coatings protect sensitive electronics from interference and short circuits
- Why full-stack coatings providers can simplify specification and procurement for complex builds
- How advanced coatings contribute to sustainability goals through reduced material use and PFAS-free formulations
Strategic Insight: Coatings Have Become a Core Engineering Discipline, Not a Finishing Step
Data centers operate under physical and operational pressures that few other facility types face. They demand near-constant uptime, generate intense and concentrated heat, and house some of the most sensitive electronic and electrical equipment in any industrial setting. As this infrastructure scales to meet AI and hyperscale demand, the materials protecting it need to keep pace.
1. The Uptime Standard Leaves No Room for Error
Data centers are commonly held to a 99.9% uptime target, often called the three nines, which allows for only a few hours of downtime per year. For business-critical sectors like healthcare, finance, and telecommunications, the tolerance for failure is even lower. Advanced coatings directly support this standard by protecting against the conditions most likely to cause unplanned outages: thermal stress, corrosion, electrostatic discharge, and fire propagation.
2. Sustainability Metrics Are Reshaping Specification Decisions
Metrics like Power Usage Effectiveness, Water Usage Effectiveness, and Carbon Usage Effectiveness have become standard benchmarks across the industry, and coatings now play a direct role in hitting these targets. Infrared-reflective coatings reduce cooling loads by redirecting solar heat away from building exteriors, while low-cure and energy-efficient formulations help facilities meet decarbonization commitments. Even though full LEED certification remains uncommon among data centers, more projects are adopting LEED-aligned strategies, making sustainable coating choices increasingly relevant to long-term facility planning.
3. Certifications Provide the Proof Points That Matter
UL standards such as UL 263 for fire resistance, UL 94 for plastic flammability, and UL 746C for electrical polymeric materials give specifiers independent verification that a coating can perform under real-world stress. IEEE standards add another layer, addressing grounding, EMI control, and arc flash safety. For high-risk environments like battery rooms or fuel cell installations, additional certifications such as UL 60079 may come into play. Together, these standards form the technical backbone that lets engineering teams specify with confidence rather than guesswork.
4. Different Components Demand Different Coating Strategies
Servers require protection against moisture, dust, and electrostatic discharge to keep sensitive electronics running continuously. Generators and transformers need robust anti-corrosion protection to survive constant exposure to environmental stress. Battery energy storage systems require dielectric coatings engineered specifically to reduce thermal runaway risk and withstand chemical exposure and thermal cycling. This component-by-component complexity means a one-size-fits-all coating approach simply does not hold up in a modern data center environment.
5. Integration Across the Coating Stack Reduces Risk
One of the more overlooked advantages of working with a full-stack coatings provider is layer-by-layer compatibility across pretreatment, electrocoat, liquid, and powder technologies. When each layer is engineered to work with the next, facilities gain consistent performance and reduce the risk of premature failure at material interfaces, a risk that becomes much harder to manage when multiple vendors and incompatible systems are stitched together under tight construction timelines.
Addressing the Operational Challenges
Specifying coatings for data centers means navigating a fast-evolving landscape of standards and operational requirements. Outdated specifications can leave critical components under-protected against today’s thermal and electrical demands. Coordinating across multiple vendors for different coating types adds procurement complexity and can introduce compatibility risks between layers. Facilities with specialized risk profiles, such as high-density battery rooms, also face additional certification requirements that need to be factored into early planning rather than addressed after construction begins.
How to Get Started
Organizations planning new builds or retrofits should begin by mapping their critical components, including servers, racks, generators, transformers, and battery storage, against the specific coating properties each requires. From there, verifying that proposed coatings meet current UL and IEEE certification standards rather than relying on older specifications is essential. Working with a single-source, full-stack coatings provider can significantly simplify this process by ensuring compatibility across the entire coating system and reducing the coordination burden across contractors and suppliers.
