Concrete
Concrete, while widely used and versatile, does have its weaknesses and potential problems that need to be understood for effective construction and maintenance.
Cracks
Concrete is prone to cracking due to thermal expansion and contraction. Cracks can compromise the structural integrity and aesthetics of the concrete.
Frost Damage
In cold climates, water can be absorbed by concrete and then freeze and expand, leading to cracks and peeling.
Alkali Reaction (AAR)
AAR occurs when reactive minerals in aggregates react with the alkali content of cement, forming a gel that expands over time. This expansion can cause cracks and reduce the concrete's durability.
Permeability
Concrete is inherently porous, allowing the penetration of water, gases, and other substances. High permeability can lead to problems such as water ingress, which can cause internal damage and corrosion of the concrete.
Durability Challenges
Over time, exposure to environmental factors like UV radiation, moisture, and pollutants can lead to a reduction in the concrete's durability, especially in harsh climates.
These weaknesses and challenges highlight the need for measures to enhance the performance and longevity of concrete structures. Efforts are being made to develop improved concrete formulations, coatings, and construction techniques that address these issues and promote a more sustainable and resilient built environment.

These coatings offer numerous benefits, such as improving visibility for automobile windows and prolonging the lifespan of glass and ceramics in general. They are driving pioneering advancements in material innovation.
Hydrophobic coatings applied to surfaces like windows, paint, lights, and rims in the automotive industry offer resistance against wear, preserve the paintwork, and enhance visibility during rainy conditions. In construction, hydrophobic coatings maintain the aesthetic appeal of glass facades and windows while simplifying maintenance through the effective washing away of dirt and contaminants by rainwater.
Electronic devices also benefit from hydrophobic coatings, maintaining clarity on screens and shielding sensitive electronic components from water damage while offering scratch resistance. They are also useful in kitchen and bathroom settings, simplifying cleaning and promoting surface hygiene by repelling water and preventing the accumulation of stains.
Medical equipment employs ceramics in various devices, where hydrophobic coatings enhance biocompatibility, deter water absorption, and minimize the risk of bacterial growth. Check out our Onyx Coating product for more details on ceramic coatings.
Plastic and metal
Hydrophobic coatings are becoming more popular in various industries, particularly on plastic and metal surfaces. These coatings use advanced nanotechnology to create a thin layer that changes the surface properties of the material. This results in surfaces that are water-repellent, self-cleaning, antibacterial, anti-corrosive, and more durable.
Hydrophobic coatings are especially useful for strengthening the durability and functionality of plastic products, such as electronic devices and outdoor equipment. The coatings protect against water, moisture, and environmental pollutants, helping to prevent damage and ensure longevity and reliability. They also provide UV protection.
Metal surfaces also benefit from hydrophobic coatings as they act as a shield against corrosion. In marine environments, constructions, and aerospace, where metals are often exposed to moisture and other corrosive elements, the coatings help to prevent damage to the materials.
Another advantage of hydrophobic coatings is their positive environmental impact. By reducing the need for frequent cleaning and maintenance, they contribute to water conservation and reduce the use of chemicals. They also extend the lifespan of products, reducing their overall environmental footprint.
Wood and MDF
Wood is a natural material that can be damaged by water, causing warping and decay over time. Hydrophobic coatings act as a protective shield, preventing water from getting into the wood. This is especially beneficial for outdoor uses like porches, fences, and furniture. By using SiO₂ coatings, these structures gain increased resistance to rain, moisture, snow, and other environmental factors, which helps to prolong their lifespan.
Medium-density fibreboard (MDF) is a composite material made of wood fibers and resin, commonly used in furniture and interior design. Applying hydrophobic coatings adds an extra layer of protection against water absorption, preventing issues like swelling, delamination, and material deterioration. This is particularly important in places with high humidity or the potential for spills, such as kitchens and bathrooms. Hydrophobic coatings can be easily applied to MDF surfaces using a spray method, creating a water-repellent barrier that helps maintain the structural integrity and visual appeal of furniture and interior components.
Graffiti
Graffiti poses challenges for maintaining public and private property, often requiring significant time and resources for cleaning. However, nanotechnology-based coatings provide an innovative solution by applying advanced materials with unique properties that repel graffiti and simplify the removal process.
These coatings can create superhydrophobic or oleophobic surfaces, making it difficult for paint or varnish to stick. This means that graffitied surfaces become unattractive to graffiti materials, causing them to slide off or be repelled by the coated surface.
Additionally, some nano-coatings have self-cleaning properties. When exposed to sunlight, photocatalytic nanoparticles in the coatings break down organic substances like paint pigments. This helps automatically remove graffiti over time, reducing the need for manual cleaning.
Moreover, nanotechnology-based coatings make graffiti removal more effective and less damaging to the underlying surface. Acting as a protective barrier, they prevent graffiti from adhering tightly to the substrate.
Implementing nanotechnology-based coatings is a proactive and effective approach to preventing and managing graffiti. These coatings offer a durable solution that minimizes the impact of graffiti on public and private property.

Mohs Scale
The MOHS scale of mineral hardness is a qualitative scale that characterizes the scratch resistance of different minerals through the ability of one mineral to scratch another mineral. It was developed by Friedrich Mohs, a German mineralogist, in 1812. The scale consists of ten minerals arranged in increasing order of hardness, each mineral capable of scratching the mineral below it on the scale. A mineral lower on the scale can be scratched by those higher on the list.
Here is the list of minerals on the MOHS scale, from softest to hardest
1.
Talc (Mg₃Si₄O₁₀(OH)₂)
Absolute hardness: 1
2.
Gypsum (CaSO₄2H₂O)
Absolute hardness: 3
3.
Calcite (CaCO₃)
Absolute hardness: 9
4.
Fluorite (CaF₂)
Absolute hardness: 21
5.
Apatite (Ca₅(PO₄)₃(OH-,Cl-,F-))
Absolute hardness: 48
6.
Feldspar (KAISi₃O₈)
Absolute hardness: 72
7.
Quartz (SiO₂)
Absolute hardness: 100
8.
Topaz (Al₂SiO₄(OH-, F-)₂)
Absolute hardness: 200
9.
Corundum (Al₂O₃)
Absolute hardness: 400
10.
Diamond (C)
Absolute hardness: 1600
Diamond, the hardest mineral on the scale, has a hardness value of 10 and can scratch all other minerals. Talc, with a hardness of 1, is the softest mineral on the scale. Mohs scale is widely used in mineralogy, geology, archaeology and material science to assess the hardness of various minerals and materials. Remember that the Mohs scale gives a relative measure of hardness and the intervals between the different minerals are not uniform in terms of actual hardness values.
Antibacterial
Hydrophobic and superhydrophobic coatings that repel water have gained a lot of attention because of their unique properties and potential use in preventing bacterial growth. Here's a summary of how these coatings work as antibacterial barriers.
Hydrophobic Coatings
These coatings are designed to minimize moisture on a surface by repelling water droplets. They are created by changing the surface chemistry of the material to make it less attracted to water.
Superhydrophobic Coatings
These coatings take hydrophobicity to the extreme, with exceptional water repellency. They often have micro/nanostructures that mimic the Lotus Effect, causing water droplets to bead up and roll off the surface.
SiO₂ (Silicon Dioxide)
SiO₂ nanoparticles have antibacterial properties. They interact with bacterial cell membranes, disrupting them and causing bacterial death.
TiO₂ (Titanium Dioxide)
TiO₂ is known for its ability to generate free radicals when exposed to UV light, which has an antimicrobial effect. This property is often used for antibacterial purposes.
Incorporation for Antibacterial Protection
SiO₂ and TiO₂ nanoparticles can be included in hydrophobic or superhydrophobic coatings to give them antibacterial properties.
Photocatalytic Activity
If TiO₂ is used in the coating, exposure to UV light activates its antibacterial properties by producing free radicals.

Antimicrobial
The term "hydrophobic" means "afraid of water" and hydrophobic coatings create a water-repellent barrier on surfaces. This property helps prevent water and other liquids from sticking to the surface, and also stops the attachment and spread of bacteria, viruses, yeast, and fungi.
The reason hydrophobic surfaces have these effects is because they create an inhospitable environment for bacteria. This makes the surfaces water-repellent and prevents conditions that lead to bacterial adhesion and colonization. Hydrophobic coatings also play a key role in preventing the formation of biofilms, which are complex collections of microorganisms that can cause persistent infections on surfaces.
Our antimicrobial solution is made by combining two environmentally friendly compounds, silicon dioxide (SiO₂) and bioflavonoids, into a three-dimensional coating. The combination of SiO₂ and bioflavonoids protects surfaces against bacteria, viruses, and fungi. The SiO₂ forms a barrier that prevents microbes from being absorbed, while the bioflavonoids kill microbes on contact. This coating lasts for up to six months, providing long-lasting protection.
Our solution has been proven effective against a wide range of bacteria, fungi, and viruses, including SARS Cov 1, Norovirus, influenza, swine flu, bird flu, MRSA, E-Coli, Salmonella, and Campylobacter. It is EN 14476 certified, meaning it has been tested and proven to be effective against encapsulated viruses like Coronavirus, as well as non-encapsulated viruses such as Norovirus.
