Conformal Coatings Market: From 'Environmentally-Friendly' to Suitable for 'Harsh Environments'

The global conformal coatings market has grown steadily in the past few years, with the increasing prevalence of electronic circuits in a mounting number of industrial applications. As the demand surged in various end-use industries, especially in consumer electronics, the conformal coatings market reached a valuation of ~ US$ 10 billion in 2018. However, growing concerns about the environmental impact of solvent-based protective coating materials and operating technologies have resulted in the imposition of environmental legislations on the use of conformal coatings.

In recent years, the conformal coatings market has evolved from solvent-based conformal coatings to their solvent-free and more efficient variants, to comply with strict environmental regulations. Challenges related to the use of solvent-based conformal coatings are triggering the demand for their solvent-free and water-based alternatives. The global conformal coatings market is expected to witness ~ 5.5% year-over-year growth in 2019 over 2018. Market players are likely to capitalize on the increasing penetration of electronic devices in various industrial segments, and foray into the ones with harsh operating environments, in the coming years

Though the consumer electronics industry accounts for over one-fourth revenue share of the conformal coatings market, stakeholders are tapping into the potential in end-use industries such as aerospace, defense, and marine. The constant hunt for conformal coating materials that can be suitable for extreme environments is attracting investors in these end-use industries. As the electronics industry is converging with nearly every other industrial segment, the demand for efficient conformal coatings is likely to be on an upward swing in the coming years.

On the other hand, the conformal coatings market will always be under the threat from its alternatives such as potting and encapsulation, especially in applications where extreme environment protection is required, notwithstanding conformal coatings’ ease of use. End users’ confidence in the protection provided by potting and encapsulation resins may negatively impact the growth of the conformal coatings market.

Demand to Shift from Acrylic to Silicone and Polyurethane in the Conformal Coatings Market

On account of their availability, reparability, and ease of use, acrylics account for nearly one-third share in the conformal coatings market. As acrylics combine good environmental protection with reasonable pricing, they will continue to be deployed widely among both, large companies as well as small businesses in the conformal coatings landscape. However, end users’ inclination towards water-based and solvent-free conformal coating materials is expected to boost the adoption of silicone and water-based polyurethane in the future.

Polyurethane offers excellent abrasion resistance and better protection against moisture, when compared to acrylics in conformal coatings. Further, silicone is also emerging as one of the most deployed conformal coating materials, as it covers a wide family of various materials with diverse properties and applications. Taking into consideration the increasing deployment of silicone and polyurethane, leading manufacturers in the conformal coatings market are likely to focus on offering silicone and polyurethane products in the years to come.
