Hydrophobic coating makes surfaces effectively repel water

Hydrophobic literally means afraid of water meaning that when a coating is hydrophobic, the coated surface fears water. In practice this means that the surface repels water by turning it into a shape of a column not letting it wet the surface. Besides protecting from water and other liquid spills, the hydrophobic coating makes its substrate easy to clean and generally improves durability. The properties of a hydrophobic coating are beneficial for domestic commercial and industrial applications from shoes to windshields to heavy duty machinery.

In this article we will take a closer look at the two types of water repellent nano coatings, outline several applications across sectors as well as providing you with an overview on hydrophobic coating manufacturers and prices in India.

The 2 types of hydrophobic coatings

There are two types of technologies that allow for hydrophobic properties. These include hydrophobic coating based on nanotechnology and fluoropolymer coatings which also repel water and dirt.

1. Nano hydrophobic coating

Hydrophobic coating and hydrophobic spray can be used to make textile waterproof.

Applications: medical supplies, electronics, automotive protective coatings and textile industry  – medical equipment, hydrophobic clothing and shoes as well as hydrophobic coating for cars (in India especially handy during the Monsoon season) protecting car paint and windshield for better visibility.  These coatings are also used as a measure to fight graffiti vandalism or public urination.

A nano coating uses nano materials and particles to create a barrier that protects a substrate on the nanoscale. In the case of hydrophobic coating the active ingredient is silicon dioxide. The coating bonds chemically with the substrate, becoming part of it. The surface of a nano coating has very low surface energy, which makes it hydrophobic – the water cannot “wet” the surface and is unable to adhere to it. This makes them easy to clean and scratch resistant. Nano coatings are transparent, thin film layers which are often indistinguishable from the uncoated substrate. The consumer products are usually in a form of hydrophobic spray to make it easy to use on substrates from windshields to clothing.

The nanoparticle products can further be divided into two groups:

  • Superhydrophobic coatings have a water contact angle bigger than 150 degrees. The sliding angle of superhydrophobic coatings is less than 10 degrees.
  • Hydrophobic coatings have a water contact angle of 90 degrees or higher. This coating is more durable compared to the superhydrophobic coating.

2. Fluoropolymer hydrophobic coatings

Applications: industrial applications in the oil and gas, construction, automotive, food processing, and aerospace industries. Consumer applications include non-stick cookware and fabrics like Gore-Tex.

A fluoropolymer coating is a general term for a class of non-stick coatings (including Teflon, Xylan, Excalibur, and Fluon), which are so named because they contain fluorocarbons. The strong bond between fluorine and carbon gives the fluoropolymer coating its water (and oil) repellent qualities.

Fluoropolymers are also non-stick, abrasion resistant, low-friction, have excellent heat resistance and thermal stability, and are chemical resistant. They also come in a wide range of colours and can be applied at different film thicknesses depending on the application.
