Conformal coatings are thin polymeric protective coatings widely applied on printed circuit boards and other electronic components. They provide protection from moisture, dirt, chemicals, and other environmental hazards, thus increasing the lifespan of electronic devices. The conformal coatings market has been witnessing high demand across industries such as consumer electronics, automotive, aerospace, industrial, and medical. The miniaturization of electronic components and need for protection from harsh environmental conditions have boosted the demand for conformal coatings.

The global conformal coatings market size was valued at US$ 1256.8 million in 2022 and is anticipated to witness a compound annual growth rate (CAGR) of 6.04% from 2023 to 2030.

Key Takeaways
Key players operating in the conformal coatings are Altana, Chase Corp., CHT Ltd, Dow, Dymax, HK Wentworth Ltd, H.B. Fuller Company, Henkel AG and Co. KGaA, ITW, Kisco Ltd, MG Chemicals, Panacol-Elosol GmbH, Shin-Etsu Chemical Co. Ltd, and Momentive. Altana and Henkel dominate the global conformal coatings market.

Key opportunities in Conformal Coatings Market Trends include increasing demand from developing countries, advancement of 5G technology increasing the demand for precision electronics, and growing aerospace manufacturing and aircraft fleet. The growing electronics industry in emerging nations such as India, Brazil, and China will boost the sales of conformal coatings in the upcoming years.

Major players are expanding their operations across the globe to capitalize on high growth opportunities. For instance, in February 2022, Dymax expanded its conformal coating manufacturing capacity in the US to cater to the growing demand from the automotive electronics market. Henkel also expanded its business in China through new application laboratories and research centers.

Market Drivers and Restrain
The primary driver for the conformal coatings market is the growing electronics industry. Consumer electronics such as smartphones, tablets, laptops, and wearables incorporate large circuit boards and components that require moisture and environmental protection, thereby driving sales of conformal coatings. The automotive industry is also adopting more electronic components in vehicles with the proliferation of advanced driver assistance systems, connected car technology, and electrification of vehicles. This is positively impacting the conformal coatings market.

However, stringent environmental regulations regarding solvent-based coatings hamper the market growth. Most conformal coating materials contain volatile organic compounds (VOCs) that emit pollutants during the coating process. Nevertheless, manufacturers are increasingly focusing on developing eco-friendly water-based and 100% solids UV-cured conformal coatings to overcome this restraint.

Segment Analysis
The Acrylic conformal coatings sub segment dominates the market currently due to its low cost and availability. Acrylic conformal coatings have resistance to moisture and offer protection against mechanical damage and erosion. They are extensively used for PCB coatings. The Silicone conformal coatings segment is expected to grow at the fastest pace during the forecast period owing to its excellent dielectric and chemical resistance properties. It has high adhesion and can withstand more extreme temperatures as compared to acrylic coatings.

Global Analysis
The Asia Pacific region holds the largest share in the conformal coatings market currently due to the growth of the electronics industry in China, Taiwan, South Korea and Japan. The demand is driven by increased PCB production in the region owing to presence of key electronics OEMs.

North America is projected to show significant growth during the forecast period due to rising demand for coated PCBs in defense, avionics and medical applications where reliability is critical. Europe also offers lucrative opportunities for market players as the focus on renewable energy is driving the demand for power electronics which require coated PCBs.
