Market Overview
Superhydrophobicity is the water repellency and anti-wettability property of a surface or material that makes it resistant to water or any other liquids. Wide range of industries are depending on this property to provide enhanced protection against rain, dirt, ice and other unwanted contaminants.
The global superhydrophobic coatings market valued at USD 8.58 million in 2019 and expected to grow at a CAGR of 8.06% to reach a market value of USD 15.26 million by 2027.
Superhydrophobic property is imparted to any object of interest by coating of its surface with superhydrophobic composites. Superhydrophobic coatings are thin layers or molecules derived from composites of silicon, carbon nanotubes, manganese oxide polystyrene and zinc oxide polystyrene among others.
Application of superhydrophobic materials alters the contact angle of the surfaces, thereby making it water-resistant. The contact angles of a water droplet on a superhydrophobic material exceed 150 degrees. Such coatings have water repellency, anti-icing, anti-fogging and to some extent, cleaning properties. These materials are primarily used to prevent accumulation of dirt and water on optically transparent surfaces such as glasses, windshields, viewports and few electronic equipment. Superhydrophobic materials are available for commercial use over glass, metal, plastic, and fabric surfaces. The development of highly transparent coating materials that provide superior optical clarity are promoting the use of superhydrophobic coatings in advanced applications such as medical devices and defense equipment.

Market Segmentation
The roughness of carbon nanotubes (CNTs) is another key source of enhancing water repellency in surfaces. Coating with these materials exhibit both small sliding angle and high contact angle to water droplets thus letting them slide off the surface. Superhydrophobicity of CNTs are widely used to create materials with properties such as anti-icing and self-cleaning. These materials are finding extensive use in construction, textiles, optical, electronic devices and various other industries.
Also, the superhydrophobicity developed by drawing the CNTs pose additional functionality of surface heating static charge removal, leading to the wide use of these materials in power generation and aviation. CNT based superhydrophobic coatings provide protection against freezing for wind turbines and aircrafts. The widening use of these coatings in power generation and defense applications will propel the growth of this segment. High cost and complex production process of carbon nanotubes is one of the major restraints.
The global market for CNT derived superhydrophobic coatings is expected to grow at a CAGR of 8.34% and likely to reach USD 5,629.88 thousands in 2027.
Geographical Analysis
North America leads the geographical production owing to its regional players and the massive investments made in the research and development. For instance, one of the major players Aculon has doubled its laboratory space for research and production for superhydrophobic coatings. The regional players lead the global market with enormous economic recovery. Further one of the global leaders of nano-coatings, P2i Limited, claims to hold the highest share of 28% in North America.
Moreover, the increasing demand for consumer electronics such as smartphones in the US looks to propel the superhydrophobic coatings market in the forecasted years. Apple and Samsung are the leading smartphone vendors in the United States with a combined sales market share of close to 70 percent. Both companies have witnessed increasing market shares in recent years, although Samsung's market share decreased in 2019.
With the growing usage of smartphones, there is growing demand for superhydrophobic coatings in the US. The market value in the US is expected to grow with a CAGR of 8.23% during the forecast period, reaching USD 5,021.97 thousands in 2027.
Rust-Oleum, a major industry player of the US, currently holds a significant position in the global superhydrophobic coating market with industrial & consumer, Rust-Oleum® NeverWet® Oleophobic Oil Repelling Treatment which is a superhydrophobic and oleophobic coating system that repels water and oils from treated surfaces. This revolutionary product causes liquids to roll off of surfaces keeping items clean and dry.
