Nanotechnology
Nanotechnology is defined as the systematic manipulation, fabrication, or modification of structures, systems, materials, or components in the range of atomic or molecular dimensions with up to nanoscale dimensions between 1 nm and 100 nm (1 nm= 10−9 m). It is referred to as the bottom up method in which materials are created using chemical processes at nanoscale size.

Sol-Gel
Sol-gel processing transforms liquid precursors into solid networks through controlled chemical reactions. Silicon alkoxides undergo hydrolysis and polycondensation, forming three-dimensional siloxane (Si-O-Si) networks at ambient conditions.
The process enables precise control over film thickness, porosity, and surface chemistry at nanoscale, allowing the incorporation of functionalities like easy to clean, anti-corrosion, barrier effects without compromising structural integrity.

Nano Titanium Dioxide Coatings
The sol-gel method is commonly used as a direct process to create titanium dioxide coatings on various surfaces. After the preparation of the sol, the solution can be directly applied to the surface. The nanoparticles are dried and cured, and the resulting titanium dioxide coating exhibits several desirable properties, including high transparency, photo-activity, and good adhesion to the substrate. It is commonly used in applications such as self-cleaning, air purifying, and antimicrobial coatings. The sol-gel method provides an effective way to produce titanium dioxide coatings with precise control over their thickness and properties.
Nano titanium dioxide photocatalyst
Nano titanium dioxide photocatalysis is a process in which organic matter is decomposed under light radiation using nano-sized titanium dioxide particles as a catalyst. The mechanism of this process can be described as follows:
- Absorption of light: When light is absorbed by the nano titanium dioxide particles, electrons in the valence band are excited to the conduction band, leaving behind electron holes in the valence band.
- Formation of reactive species: The excited electrons and electron holes can react with adsorbed oxygen and water molecules on the surface of the titanium dioxide particles to generate highly reactive species, such as hydroxyl radicals (•OH) and superoxide ions (•O2-).
- Adsorption of organic matter: The highly reactive species generated in the second step can react with organic matter adsorbed on the surface of the titanium dioxide particles or in the surrounding solution, breaking it down into smaller, harmless molecules such as CO2 and H2O.
- Regeneration of titanium dioxide: Finally, the electron holes left behind in the valence band can react with the adsorbed hydroxyl ions to form hydroxyl radicals, which in turn can react with the excited electrons to regenerate the original titanium dioxide particles.

Automotive
EXOCOAT™ Ceramic+ forms a durable ceramic layer that shields car lacquer from UV rays, scratches, and chemical damage, preserving a glossy finish over time. Its ultra-smooth surface repels dirt and brake dust, making rims significantly easier to clean and maintain. Meanwhile, EXOCOAT™ ClearView enhances glass surfaces with extreme hydrophobicity, causing water to bead and roll off instantly, thus enabling wiperless driving in rain. Both coatings offer long-lasting protection and reduce the need for frequent cleaning, combining performance with convenience. Together, they elevate vehicle care to a new level of efficiency and style.
Architecture
EXOCOAT™ 151 is a high-performance photocatalytic coating that keeps surfaces like heritage buildings, rendered walls, solar panels, and facades clean by harnessing light to break down organic pollutants and grime. Its nano-titanium oxide formula produces a superhydrophilic surface that lets rainwater rinse away dirt without streaks, while also breaking down airborne contaminants like VOCs and NOx under visible light. This helps lower maintenance needs and protects the surface over time.
OEM
EXOCOAT™ coatings can be seamlessly integrated into OEM processes under controlled conditions to provide long-term protection for components and surfaces. By forming a thin, uniform layer, they shield parts from aging effects such as UV degradation and oxidation. Their advanced chemical resistance helps prevent corrosion, even in harsh environments or during extended use. The coatings also enhance mechanical durability, reducing wear and surface damage from friction or impact. This results in extended product life, reduced maintenance, and improved performance across automotive, industrial, and consumer applications.
Glass care
Glass surfaces are constantly exposed to water, dirt, and environmental stress, which can lead to staining, reduced clarity, and frequent cleaning. Protecting glass with a high-performance coating like EXOCOAT™ ClearView not only preserves its appearance but also enhances durability and ease of maintenance.
