Nanotechnology is actually about messing with materials at the nanoscale, less than a micrometre. Nanotechnology involves the study of very small particles at the scale of molecules and even atoms, which in recent years have made significant progress in various industries, including wood, automotive, home appliances and electronics. In recent years, paints have entered the world of nano as one of the most widely used materials in various industries, and different types of nanocoatings have been made and available in accordance with different industries.
What are Nanocoatings?
Paints have a number of fundamental weaknesses in every industry and on every surface applied. Many paints are vulnerable to heat, impact, scratches and water. As mentioned above, nanotechnology studies the atoms and particles that makeup materials. In the paint industry, nanotechnology has tried to improve the properties of paint and create new properties in paint particles and make it possible to use it on a larger scale by considering the properties and behaviours of paint particles under different conditions.
The Most Important Functional Properties And Benefits Of Nanocoatings
- Can be used in painting and insulation of various surfaces in construction
- Saving energy consumption in buildings
- They are water and do not need solvents and are therefore considered nature lovers.
- Water-resistant to rain penetration and ambient humidity
- Can be used in different parts of the building, including the facade and roof in different weather conditions
- They have high adhesion strength and can be applied on any type of surface
- They need little cleaning and cleaning
- Resistant to the growth of bacteria and fungi
- Ability to create rock spectra by adding different pigments
- Easy to implement and no need for special equipment
- High durability and resistance to airborne particles
Types Of Nanocoatings In The Construction Industry
In general, based on the specific applications and properties created in paint, we can enumerate 8 types of nano paints that have wide applications in the construction industry.
- Anti-corrosion paint
- Waterproof paint and waterproofing
- Antibacterial paint
- Thermal insulation paint
- Anti-scratch paint
- Self-healing paint
- Anti-reflective paint
- Indescribable color
Nano paints play a very important role in protecting surfaces and products against all kinds of corrosion. Anti-corrosion paints protect metal parts from rust and corrosion due to moisture, oxidation and exposure to weather and industrial chemicals.
Nanocoatings that are added to the surface of metallic materials actually act as a barrier against contact between chemicals or fluids with the desired surface and therefore have a significant impact on the durability and longevity of the desired surface.
Undoubtedly, one of the most widely used applications of nano-paints is to create water-resistant or so-called waterproof surfaces. Using these types of paints, a variety of products such as clothing, electronics, furniture and glass can be waterproof or hydrophobic.
In addition to being waterproof, this type of paint keeps the surfaces clean and saves time and money for cleaning the surfaces and products in question. These types of paints, in addition to being waterproof, have very good resistance to oil and in general any fluid and liquid material.
Nano Antibacterial Paint
Antibacterial nano-dyes help prevent or minimize the growth of microorganisms on surfaces. The healthcare industry is one of the areas in which these dyes play a vital role in preventing the spread of infections.
In addition, antibacterial paints are now used in public places and on surfaces that are in constant contact with people’s hands, such as door handles or guardrails, and are therefore widely used in subways and buses. Other applications of antibacterial paints include their use in kitchens, air conditioners, and food factories and food packaging plants.
Thermal Insulation Paint
Nano-paints with thermal insulation properties play an important role in aviation and the aircraft industry. This type of anti-heat paint is generally used on metal surfaces that will be exposed to high temperatures. For example, they can be used in gas turbines and parts of spacecraft engines.
Nano Anti-scratch Paint
Scratches and abrasions are adverse effects caused by regular and continuous use of parts. Scratch-resistant paints are widely used to reduce or eliminate overall wear and extend the life of parts and products. These types of paints are ideal for use in environments and appliances that cannot be lubricated. Increasing mechanical properties such as stiffness and hardness are other applications of anti-scratch nano-paints.
Self-healing Nano Paint
These types of paints are actually a good alternative to provide protection against corrosion, which also requires much less cathodic protection. These types of paints have micro or nanocapsules containing special substances that are released when the paint is damaged. These types of self-healing systems are designed for metal structures under cathodic protection and sensitive to electric fields and acidity.
This type of transparent color is widely used in making glasses. It is worth noting that these types of colors only reduce the reflection on the radiant side of the surface. These types of paints play an important role in increasing the productivity of solar panels. Although these types of nano-dyes are colorless, they can be dyed by adding desired pigments.
