Sol-gel process coatings in the automotive industry are an advanced technology that allows thin layers of protective and functional materials to be applied to the surface of automotive parts. This technique is widely used to improve the performance, aesthetics and durability of automotive components.

Here is a description of the functions of the automotive coatings that Nanoprom has developed for its customers:

1. Corrosion protection: sol-gel coatings are often used to protect metal surfaces from oxidation and corrosion. These coatings form a thin, homogenous protective layer that prevents direct contact of the metal with the aggressive environment, such as moisture, road salts and air pollution. This helps to extend the service life of automotive components by minimising damage caused by corrosion.
   By using Polysil-based coatings, it is also possible to eliminate galvanic treatments and make the production of aluminium parts environmentally sustainable through the Nalucoat process
2. Friction reduction: Sol-gel coatings can be applied to reduce friction between moving car parts, such as joints and sliding surfaces. This helps improve vehicle efficiency, reducing wear and tear and increasing fuel economy.
3. Anti-reflective and anti-scratch properties: Sol-gel process coatings can impart anti-reflective and anti-scratch properties to automotive surfaces. This can improve driver visibility by reducing glare from reflections from the sun or artificial lights. It also protects surfaces from scratches caused by debris and abrasive particles.
4. Enhanced Aesthetics: Sol-gel coatings can be used to create custom aesthetic finishes on the interior and exterior surfaces of the car. They can provide a smooth, satin or glossy appearance, contributing to the visual attractiveness of the car.
5. Chemical resistance: Sol-gel coatings offer chemical resistance against substances such as oils, solvents, detergents and harsh chemicals. This is especially useful for protecting automotive surfaces from damage caused by corrosive chemicals or contaminants.
6. Thermal insulation: Sol-gel process coatings can also contribute to the thermal insulation of the car. These coatings can reduce heat transfer through surfaces, keeping the car interior cooler in summer and warmer in winter.
7. Self-cleaning surfaces: Sol-gel coatings have the ability to self-clean through the water-repellent effect. These coatings repel water and dirt particles, reducing the need for frequent cleaning and maintenance.

Nanoprom has created the Polysil family of coatings with an industrial sol-gel process, applicable to the automotive sector with extreme benefits over current technologies.
