COVID-19 IMPACT

Electronics Conformal Coating Industry Had a Negative Effect Due to Manufacturing Slowdown during the COVID-19 Pandemic

The global COVID-19 pandemic has been unprecedented and staggering, with the market experiencing lower-than-anticipated demand across all regions compared to pre-pandemic levels. The sudden market growth reflected by the rise in CAGR is attributable to the market’s growth and demand returning to pre-pandemic levels.

A number of electronics and automotive factories were closed down for a shorter period of time during the pandemic's initial stages, which resulted in a rapid decline of the demand for conformal coatings. This decline had an impact on both the suppliers of the raw materials and those providing the coating services. Lockdowns along with the imposed travel restrictions led to a disruption in the global supply chain for raw materials and coating chemicals.

The pandemic was a major catalyst in the production and acceptance of medical electronics like ventilators, patient monitoring systems, and diagnostic equipment. These devices needed tough electronic assemblies, which would be protected by conformal coatings, to ensure reliability and so they would no way be shorted by their lifetime. This whole scenario resulted in the coating materials and technologies' demand to skyrocket.

MARKET DYNAMICS

Driving Factors

Increasing Adoption of Consumer Electronics to Boost the Market

A factor in the electronics conformal coating market growth is increasing adoption of consumer electronics. The fast growth of smartphones, smart wearables, tablets, and home automation systems is resulting in huge demand for conformal coatings. These coatings are applied to the circuit boards in different environmental conditions to guard them against corrosion, moisture, and dust. The shifting of the consumer electronics market towards more reliable, compact, and lightweight devices has made it necessary for coatings to be very thin and thus, a vital consideration in the design process. The amount of global consumer electronics production has gone up tremendously, so the suppliers of conformal coatings have also been enlarging their capacity with new, flexible materials. One of the main reasons behind the auto sector’s shift towards electric and autonomous vehicles is the increased utilization of delicate electronics in cars which has subsequently raised the demand for those electronic components.

Technological Advancements to Expand the Market

Continued Research and Development (R&D) endeavors have resulted in the development of high-tech coatings including parylene, silicone hybrids, and nanocoatings. These materials are superb in terms of dielectric properties, adhesion, and flexibility while also providing robust resistance to both thermal and chemical stress. On top of that, eco-friendly formulations like water-based coatings are gaining acceptance owing to their compliance with environmental regulations. Such innovations not only help in widening the product range but also in keeping the technology of the industry up to date. Automation has spread through different industries, and at the same time, it has led to an increase in the requirement for reliable electronic components which are going to function without problems in the harshest industrial environments.  

Restraining Factor

Environmental Regulations and High Cost to Potentially Impede Market Growth

A lot of traditional coatings emit solvents that release volatile organic compounds (VOCs), which in turn cause the setting of more severe environmental regulations. The adherence to these laws compels the companies to make investments in green technologies and solvent recovery systems thus increasing their operational costs. Moreover, the change to the environmentally friendly formulations entails the alteration of the legacy products, which may be a cause of the production efficiency disruptions. High-end coatings such as parylene and silicone need special vacuum deposition and curing systems which add significantly to the manufacturing costs. This makes it difficult for small and medium-sized producers to implement cutting-edge technology.

Development of Eco-Friendly Coatings To Create Opportunity for the Product in the Market

Opportunity

The coatings sector is progressively moving towards water-based, low-VOC, and UV-curable coatings that not only comply with environmental standards but also provide excellent protection. Innovation in eco-friendly coatings will secure a competitive edge for manufacturers as sustainability turns into a worldwide concern. The worldwide implementation of 5G technology and the increase of IoT devices in smart homes, cities, and industries provide enormous opportunities.

These devices, which are typically situated in outdoor environments, depend on proper coatings to keep delivering their performance. Ultra-thin coatings that do not interfere with signal transmission are in great demand and such demand is increasing rapidly.

Limited Standardization Could Be a Potential Challenge for Consumers

Challenge

There is no global standard for the performance, testing, or measurement of conformal coating thickness presently. The absence of a common standard leads to differences in the quality of these products, and a problem in the industry as to their use in different markets. Once the coating has been applied to the component it is very difficult to do any rework or alteration to the product, particularly if the hard coatings such as epoxies or parylenes are used.

Manufacturers must plan their production very carefully to limit the need for any rework, which in the end makes any assembly line more difficult. The changing prices of the different resins, silicones, and solvents used have a direct bearing on the production costs. The market instability due to political pressures or supply problems may induce adverse pricing policies and profits in this area.
