Hydrophobic coating often refers to a type of low surface energy coating with a static water contact angle θ greater than 90° on the smooth surface of the coating, while superhydrophobic coating is a new type of coating with special surface properties, which refers to the water contact of the solid coating The angle is greater than 150° and often means that the water contact angle hysteresis is less than 5°.
2017 --2022 years, the hydrophobic coatings market will grow at an annual compound growth rate of 5.
5%, in 2017 the city of hydrophobic coatings
field size of 10,022.
5 tons, the market size in 2022 will reach hydrophobic coatings 13,099 tons.
The growth of end-user demand and the excellent performance of hydrophobic coatings promote the development of the hydrophobic coatings market.
The growth of this market mainly depends on the growth of end-user industries such as automobiles, construction, marine, aerospace, medical and electronics.
Due to the growth of the construction industry, hydrophobic coatings for concrete substrates are expected to reach the highest compound growth rate during the forecast period.
Use a hydrophobic coating on the concrete to avoid concrete expansion, cracking, scaling and chipping.
These hydrophobic coatings protect the concrete surface by increasing the contact angle of the water droplets with the concrete surface.
During the forecast period, automobiles will become the fastest growing terminal industry in the hydrophobic coatings market.
The increase in automobile production will drive the automotive industry's demand for hydrophobic coatings.
In 2017, the Asia-Pacific region will account for the largest share of the hydrophobic coatings market, followed by North America.
This high growth is due to the increasing demand for automobiles in the region, the increasing innovation in the aerospace industry, and the increasing number of start-ups in the medical device industry.
Environmental regulations are considered to be the main constraints on the hydrophobic coatings market.
Some manufacturers develop new products in order to be competitive in the market, but at the same time meeting environmental regulations will be time-consuming and laborious.
The types of hydrophobic coatings can be subdivided into: polysiloxane based hydrophobic coatings, fluoroalkylsiloxane based hydrophobic coatings, fluoropolymer based hydrophobic coatings and other types, which are widely used in construction, engineering facilities, automobiles, aviation and other fields .
The coating process of hydrophobic coatings can be subdivided into: chemical vapor deposition method, microphase separation method, sol-gel method, electrostatic spinning method, etching method, etc.
Hydrophobic coatings can be subdivided into: self-cleaning hydrophobic coatings, anti-fouling hydrophobic coatings, anti-icing hydrophobic coatings, antibacterial hydrophobic coatings, anti-corrosion hydrophobic coatings, etc.
according to their performance.
