Corrosion under Insulation (CUI) and Spray-on Insulation (SOI) Coating - Worldwide

The global corrosion under insulation (CUI) and spray-on insulation (SOI) coating market size was exhibited at USD 2,119 million in 2024 and is projected to hit around USD 3,585 million by 2034, growing at a CAGR of 5.4% during the forecast period 2024 to 2034.

The corrosion under insulation (CUI) and spray-on insulation (SOI) coating market is experiencing steady growth owing to increasing industrial demand for enhanced asset protection and maintenance. The applications of such coatings are indispensable to prevent corrosion, thus protecting long-term durability for critical infrastructure, especially in the oil and gas, energy, and marine sectors. Advances in coating technologies, such as nanocomposites materials and improved application methods, drive performance and increase the lifespan of these coatings. The market is also being expanded by growing concern for sustainability and the adoption of low-VOC coatings that are friendly to the environment.

The growth factors in the corrosion under insulation (CUI) and spray-on insulation (SOI) coating market include a growing awareness of the importance of corrosion protection, increasing adoption of preventive maintenance strategies, and growth in key industries such as energy and construction. However, the market is not without its challenges. Economic fluctuations, lack of skilled labor, and risk of coating failure because of improper application or inadequate quality control can be obstacles to growth. Competition among players in the market is increasing, leading to pressure on prices and margins. Despite these challenges, the demand for CUI and SOI coatings remains strong, particularly in emerging economies and regions like South Korea, the United States, and China, where industrial growth continues to create significant opportunities for innovation and market development.
