Global Corrosion Under Insulation (CUI) and Spray-On Insulation (SOI) Coatings Market – Key Trends & Drivers Summarized

Why Is Corrosion Under Insulation Emerging as a Silent Killer in Industrial Infrastructure?

Corrosion Under Insulation (CUI) has become a critical concern for industries relying on thermal insulation, particularly in sectors such as oil & gas, petrochemicals, power generation, and marine. CUI refers to the corrosion of carbon and low alloy steel under insulation due to the ingress of water. While insulation is essential for energy efficiency and personnel protection, it can ironically create a corrosive environment if moisture penetrates the protective layers. This stealthy deterioration often goes undetected until severe damage has occurred, leading to unplanned downtimes, safety hazards, and massive financial losses. As awareness increases, the demand for specialized coatings that prevent CUI has risen, with epoxy-based and hybrid coatings taking center stage. These coatings serve as a robust barrier between the substrate and the corrosive agents, effectively reducing the risk of degradation. Furthermore, stringent asset integrity standards enforced by regulatory bodies such as NACE International and ISO have compelled industries to proactively invest in CUI mitigation systems.

How Are Innovations in Spray-On Insulation Coatings Transforming Industrial Maintenance?

Spray-On Insulation (SOI) coatings have rapidly advanced from being niche solutions to becoming mainstream thermal management and corrosion prevention tools. Unlike traditional insulation systems involving multiple layers and mechanical fittings, SOI coatings offer a seamless, adhesive application that reduces installation time and thermal bridging. Recent developments in ceramic-filled and nanotechnology-enhanced spray coatings have not only improved thermal resistance but also added hydrophobic and UV-resistant properties, broadening their applicability across offshore platforms, pipelines, refineries, and chemical plants. The ease of application, reduced maintenance frequency, and dual functionality of thermal insulation and corrosion protection are driving interest in SOI. Market leaders are continuously enhancing product performance by focusing on fast curing times, low VOC content, and eco-friendly formulations, which align with broader sustainability goals across industrial sectors. In addition, SOI’s compatibility with complex geometries and aging infrastructures gives it an edge over conventional wraps and claddings.

What Role Does Regulatory Pressure and Asset Integrity Play in Shaping Demand Patterns?

In recent years, the role of regulation has evolved from a compliance necessity to a core business imperative, significantly influencing the demand for advanced coating technologies. Governments across developed and developing economies are mandating regular inspection and maintenance of critical infrastructure, particularly in high-risk zones such as chemical storage units and offshore platforms. The increasing adoption of Risk-Based Inspection (RBI) methodologies, corrosion mapping tools, and digital twin technologies is driving demand for high-performance CUI and SOI coatings. Companies are under pressure not only to comply with these standards but also to extend asset life cycles and reduce environmental liabilities. Insurance companies are also scrutinizing the CUI mitigation strategies of asset owners, which has made investments in protective coatings a risk-mitigation strategy as much as an operational one. This trend has particularly been pronounced in Asia-Pacific, where rapid industrialization combined with tropical climates exacerbates CUI risks. Meanwhile, Europe and North America continue to push ahead with aging industrial bases that require retrofitting and re-coating solutions.

What’s Fueling the Growth of the CUI and SOI Coatings Market?

The growth in the corrosion under insulation (CUI) and spray-on insulation (SOI) coatings market is driven by several factors rooted in technology evolution, end-user demands, and risk management priorities. The increasing complexity and aging of industrial infrastructure—especially in the energy, chemicals, and maritime sectors—necessitate reliable corrosion mitigation strategies, pushing the adoption of advanced coatings. Rising investments in brownfield and greenfield projects across Southeast Asia, the Middle East, and Latin America have also boosted demand. Technological advances in coating materials such as polysiloxane, fluoropolymer, and hybrid epoxy systems are further enhancing product lifecycle and application versatility. End-users are increasingly opting for solutions that provide a dual function—thermal insulation and corrosion resistance—especially for irregular surfaces and hard-to-reach areas. Growing awareness about lifecycle cost savings, along with a shift toward digital maintenance and asset monitoring, is encouraging proactive CUI prevention. Moreover, consumer behavior within industries has changed—from reactive maintenance to predictive asset management—making high-performance coatings a foundational element of industrial strategy.
