Growing complexity and miniaturization of electronics
The growing complexity and miniaturization of electronics are significantly driving the demand for advanced conformal coatings. As electronic devices shrink in size and become increasingly complex, the demand for high-precision and reliable protection also grows. For instance, a group of scientists at the University of Ottawa has recently made a crucial breakthrough in developing back-contact micrometric photovoltaic cells, which marked an important milestone in the development of miniaturized solar technologies. This is part of a trend in which devices continue to shrink in size and components are smaller than ever. The demand for protective conformal coatings for delicate electronics, particularly in domains such as microelectronics and nanotechnology, is increasing with each passing day. An IPC report by Association Connecting Electronics Industries shows that a whopping 45% of manufacturers now use nano-coatings or other advanced technologies to cater to the needs of smaller and more complex devices. Manufacturers have adapted by developing new formulations, including high-performance UV-cured coatings and flexible coatings, to provide long-term reliability and durability for more highly miniaturized electronics.
Rising Demand for High-Reliability Electronics
The rising demand for high-reliability electronics is supporting the growth of the market. As electronic devices are increasingly integrated into the daily lives of individuals, there is a heightened emphasis on ensuring their long-term performance and durability. This is influencing the growing requirement for electronic components and circuitry to withstand harsh environmental conditions, including moisture, dust, chemicals, and temperature fluctuations. For instance, in January 2024, Indium Corporation proudly showcased its proven advanced assembly materials for power electronics, including the rapidly evolving electric vehicle (EV) manufacturing and e-mobility market, at NEPCON Japan. Indium Corporation's products for power electronics have been demonstrated to reduce energy consumption and solve warpage issues for its customers while ensuring high reliability and improving overall efficiency.

For example, UV-cured coatings reduced curing times from several hours to mere seconds, greatly increasing production efficiency. Nanocoatings, which have superior moisture and chemical resistance, are now widely used in automotive electronics, improving the longevity and reliability of components exposed to harsh conditions. Moreover, it has been observed that AOI system implementation increased the accuracy in detecting coating defects by over 30%, thus maintaining quality standards in the manufacturing process. This has led to increasing demand for these advanced coatings in electronics, automotive, aerospace, and medical device segments. In May 2022, HumiSeal launched a new product designed to reduce bubbles in conformal coatings, further driving growth in the market.
Acrylic leads the market with 46.8% of market share in 2025. Acrylic conformal coatings are a type of protective coating used in electronics and other industries to protect printed circuit boards (PCBs) and electronic components from environmental factors, including moisture, dust, chemicals, and physical damage. They are typically composed of acrylic resins dissolved in a solvent. These resins can provide good protection against moisture and environmental contaminants. Acrylic conformal coatings are applied to the surface of PCBs and components to create a thin, protective coating that conforms to the shape of the substrate. They are known for their ability to provide excellent moisture resistance, which makes them suitable for applications in humid or damp environments, thus driving the conformal coatings market demand.
Solvent-based conformal coatings are protective coatings used in electronics to shield PCBs and components from environmental factors. They contain solvents for application and typically offer good protection against moisture and contaminants.
Ultraviolet (UV)-cured conformal coatings are protective coatings used in electronics. They are applied as a liquid and then cured rapidly using UV light. This curing process offers fast and precise coating applications, making them suitable for high-volume production. UV-cured coatings provide efficient protection against moisture and chemicals while minimizing production time.
Water-based conformal coatings are protective coatings used in electronics to shield PCBs and components from environmental factors. They are composed of water as a carrier and offer eco-friendliness with low volatile organic compound (VOC) emissions. These coatings protect against moisture and contaminants while being less harmful to the environment compared to solvent-based coatings.
Dip coating is a manufacturing process in which an object is immersed (dipped) into a liquid coating material, such as conformal coating, to achieve a uniform and even coating.
Spray coating is a method used to apply a thin, uniform layer of conformal coating material onto a surface using a spray gun or nozzle. This technique atomizes the coating material into fine droplets, which are then sprayed onto the substrate.
Brush coating is a manual application method where a coating material, such as conformal coating, is applied to a surface using a brush or paintbrush. It allows for precise control and is often used for smaller projects or touch-ups, providing a thicker and more controlled layer compared to spray or dip coating methods.
Consumer electronics leads the market with around 44.3% of market share in 2025. Conformal coatings play a crucial role in enhancing the reliability and longevity of consumer electronics by protecting sensitive electronic components and printed circuit boards (PCBs) from various environmental factors. They act as a barrier, preventing moisture from infiltrating the PCB and causing corrosion or electrical shorts. Additionally, they can provide thermal resistance, helping to dissipate heat generated by the electronics. In portable devices and those subject to movement, such as cameras or gaming consoles, conformal coatings help secure components against vibrations and mechanical shocks, preventing potential damage or disconnections.
