Anti-Corrosion
Antimikrobielle nanocoatinger for hygieniske, bakteriefrie overflater
Rusted metal railings illustrate how unprotected steel succumbs to corrosion over time. Advanced nanocoatings form an invisible shield to prevent such damage. Corrosion is a pervasive challenge across oil & gas, marine, infrastructure, and other industries​.
Left unchecked, rust and oxidation degrade critical equipment and structures – the global cost of corrosion is estimated around $2.5 trillion (≈3.4% of GDP) annually​ (NACE, 2017).
This leads to frequent maintenance, downtime, and even environmental hazards from leaks or structural failures. NanoTech Solutions’ anti-corrosion nanocoatings are engineered to combat this problem at the source. By leveraging nanotechnology, we create ultra-thin protective layers that isolate metal surfaces from moisture, oxygen, and corrosive chemicals. The result is a dramatically longer lifespan for assets and lower life-cycle costs for operators.

Technology & Scientific Principles
Our anti-corrosion nanocoatings work by forming a continuous nano-scale barrier that actively repels water and corrosive ions. Unlike traditional paints, these coatings incorporate advanced materials (such as sol-gel ceramics and polymer composites) that bond tightly to the substrate and fill microscopic crevices. This prevents the electrochemical reactions that produce rust.
For example, Gentoo, one of our sol-gel nanocoatings, creates a hydrophobic and chemical-resistant film – it repels water, oils, acids, and bases, effectively sealing the metal off from corrosive agents.
Another solution, SAPOE, is a thermoplastic polyester nano-powder coating that can be applied as a thick, uniform layer on steel. It’s completely solvent-free and forms a dense protective shell. The scientific principle is simple: keep the environment (water, salt, chemicals) from contacting the metal, even at the micro-level.
Nanoparticles within the coating may also serve as sacrificial corrosion inhibitors or provide cathodic protection in case the layer is breached. Furthermore, nanocoatings often leverage superhydrophobicity – by creating a lotus-leaf-like roughness, they cause water to bead up and roll off, carrying particles away with it. This lotus effect ensures the surface stays dry, which is key since moisture is required for most corrosion to propagate.

Sessile Drop
The Sessile Drop method is a way to measure how well a liquid wets a solid surface. By analyzing the angle formed between a liquid droplet and the surface, we can understand how the liquid interacts with the surface. This method is often used to investigate contact angles and is considered a fundamental technique in this field.
​
Water is usually the liquid of choice for these measurements, and the angle formed by the water droplet can tell us whether the surface is hydrophobic or hydrophilic. Hydrophilicity is particularly important when it comes to coatings, as it determines how well the surface can be wetted. The Sessile Drop method is often used as a quality control tool before applying coatings to make sure the surface has the necessary properties for optimal performance.
Pendant Drop
The Pendant Drop contact angle is another method used to measure contact angles, similar to the sessile drop method. However, in the pendant drop method, the liquid drop is suspended from a solid surface instead of being in direct contact with it. This technique is useful for examining the wetting properties of a solid surface and understanding how different liquids behave.
​
The Pendant Drop method is a valuable tool that complements the sessile drop method. It provides additional insights that are applicable across various industries, including coatings, adhesives, pharmaceuticals, and petrochemicals. The information obtained through the pendant drop method helps researchers and engineers make informed decisions and improvements in these industries.
