According to UnivDatos analysis, rising adoption of advanced PCBs, miniaturization trends, and stricter environmental and performance standards are increasing the need for durable protective coating solutions, leading to the further growth of the conformal coatings market. As per their “Conformal Coatings Market” report, the global market was valued at USD 13,375 million in 2024, growing at a CAGR of about 5.49% during the forecast period from 2025 - 2033 to reach USD million by 2033.
Conformal coatings are protective polymer layers applied to printed circuit boards (PCBs) and electronic components to protect them from environmental effects. These finishes adhere to the shapes of the parts, forming a continuous protective layer that resists moisture, dust, chemicals, temperature, and mechanical wear. Popular materials are acrylics, silicones, epoxies, urethanes, and parylene with unique performance characteristics. Conformal coatings increase device reliability and extend their life cycle by preventing corrosion, electrical leakage, and short circuits.

Shift Toward Water-Based and Sustainable Formulations
One future trend in the conformal coatings industry is the great shift to water-based and sustainable formulations as business trends transfer to minimize environmental impact and meet tougher VOC and hazardous chemical standards. Coatings made in water have reduced emissions, higher worker safety, and are easier to handle when it comes to the disposal of the waste, and at the same time provide sufficient protection to most assemblies in electronic products. Manufacturers are currently investing in environmentally-friendly chemistries such as bio-based and low-solvent options to satisfy consumer electronics, automotive, and industrial markets, which are increasingly demanding eco-friendly chemistries. These greener coatings will be adopted quickly as sustainability becomes a major buying factor, and they will redefine product innovation across the market.
For instance, in December 2024, Specialty Coating Systems (SCS) announced that it had reinforced its commitment to environmental responsibility by introducing a range of solvent-free, water-based, and halogen-free conformal coating solutions designed to reduce emissions, minimize waste, and improve sustainability across electronics manufacturing.
Frequent Product Launches and Innovation: Strategic Investments Driving Growth in the Conformal Coatings Market
The conformal coatings market is also being boosted by increasing product launches as companies are developing advanced formulations that will provide better performance and efficiency, and meet the environmental requirements. New products like UV-curing, dual-cure, and nano-coatings are opening up the opportunities of application in automotive electronics, consumer devices, industrial systems, and telecom equipment. These emerging technologies support changing industry demands such as miniaturization, improved thermal conductivity, and superior protection to intricate PCBs with wider use in manufacturing industries. Competition also increases due to frequent launches and encourages the persistent investment in the field of R&D and advances in technology, which contribute to the overall development of the market.
For instance, in February 2024, Henkel announced that it had developed and commercialized Loctite Stycast CC 8555, a solvent-free, UV-curable, UL 746E-rated conformal coating engineered for high-reliability electronics in harsh environments.
