Functional coatings are a specialized form of coating used on a surface to improve or alter its characteristics in addition to its typical protective or adorning purposes.
These coatings are intended to give the surface particular capabilities, such as greater adhesion, increased durability, corrosion resistance, anti-fouling qualities, electrical conductivity, or thermal insulation, among others.
Based on their intended uses and qualities, functional coatings can be divided into several types. Typical illustrations include:
Coatings that prevent corrosion These coatings guard surfaces against corrosion brought on by moisture, chemicals, or the environment. They create a shield that keeps corrosive substances from coming into direct touch with the surface.
Anti-fouling coatings: These coatings are used to prevent organisms like algae and barnacles from adhering to and growing on submerged surfaces. Ship hulls, offshore buildings, and marine apparatus frequently use them.
Coatings that repel water are known as hydrophobic coatings, and they enable surfaces to be water-resistant or water-repellent. They are used in electronic gadgets, textiles that are resistant to water, and self-cleaning surfaces.
Self-cleaning coatings: Through a variety of methods, such as photocatalysis or super hydrophilicity, these coatings have the power to remove dirt, stains, and pollutants from the surface. They are frequently utilized in automobile applications, glass windows, and building exteriors.
Coatings that promote electrical conductivity on a surface are known as conductive coatings. They are used in touchscreens, solar cells, electronics, and electromagnetic shielding.
The underlying substrate is shielded from high temperatures by thermal barrier coatings, which act as insulation against heat transfer. They are frequently used on furnaces, furnace components, and gas turbine parts.
Coatings that use photocatalysts to start chemical processes when exposed to light can help in air purification, pollutant degradation, and self-cleaning surfaces.
In numerous sectors, including automotive, aircraft, electronics, energy, healthcare, and construction, functional coatings are essential.
They make it possible to create new materials and surfaces with specialized features, which improve usefulness, performance, and longevity across a wide range of applications.
The Global Functional Coatings Market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
AkzoNobel Launches Website to Demonstrate Raincoat Powder Coatings’ Functional Range.
In order to help clients and specifiers of functional powder coatings through the selection process and educate them on how a Raincoat solution can enable transformative change in situations where protection determines success, AkzoNobel has developed a new dedicated website and resource center.
Customers can learn how to apply single-layer, dual-layer, and multi-layer powder coatings for projects when failure in any way is just not an option.
They can discover how various Raincoat solutions can meet highly specific needs, such as insulating the electrical systems on the newest electrical vehicles (EVs) or protecting the integrity of drinking water pipelines on the inside and exterior.
