Functional coatings for glass

Definition: What is Nanotechnology?
• The capacity to create functional materials, devices and systems
with novel functions and properties through the control of matter at the
Nano-scale.
• Nano-scale means dimensions of roughly 1 to 100 Nanometre, where
unique phenomena enable novel applications’
• Eight to ten atoms span one Nanometre.(Nm)
• Nanotechnology glass coatings are between 20 – 30 Nm for
photocatalytic Tio2 and 20 – 40 Nm Silica
The average float glass is 5,000,000 Nm thick

Surface Functions Benefits
The technology can be used for surface applications:
• Windows• Facade panels• Balustrades• Sky lights• Glass roofs
Materials can improve: • Cleaning ability• Scratch resistance • Asset protection • Shield against Pollution • Chemical resistant• Anti dust
• Can be easily reapplied
• Cost effective• Durable• Does not react with other materials• Speeds up cleaning
Nanovations products can be used on buildings
and constructions glass for external application

Nature as a template
Nature Technology
Our ability to understand and control surface wetting has dramatically improved since our ability to observe and fabricate Nano scale surface topographies has been developed

Products and Technology

High Performance Glass Coatings
Nanovations is the technology
leader in the development
of advanced glass coating solutions
for the construction industry.

Smart Surface Glass Coatings
Demonstration of the self cleaning effect on a Lotus
leaf and on a glass slide coated with NG 1010.
Water droplets take up dirt and dust.
The dirt is more attracted to the water than to the
substrate.

Glass Cleaning technology using sub-micron abrasive glass cleaner technology.
Mineral deposits on glass, before and after the cleaning with Nanovations CL 40/ CL50.
This is Nano-scale deep cleaning.
The coating performance on the well prepared glass is significantly improved.
Cleaning solutions help to solve problems prior to the application.
Nanovations is a leader manufacturer of abrasive glass cleaning products.

Protect glass from mineral deposits
The non coated glass shows mineral deposits appearing with hard water, high pollution, salt spray or rundown marks from mineral building materials.
The Coated glass is protected against staining.

Hydrophilic vs Hydrophobic
Hydrophilic NG 1314/ NG1010Protects glass during construction ? No Yes
Can be reapplied on site? No Yes
Compatible with Silicone /PU sealants ? No Yes
Works against inorganic and organic dirt ? No Yes
Is the technology cost effective No Yes
Scratch resistant limited Yes
14
UV protection without the use of pigments
15
Nanovations coating changes the surface tension. Dirt is more attracted to the water than to the surface and is easy to wash off or is removed naturally by rain.
16
Nanovations NG 1314 is the hardest wearing room temperature cured coating on the market
Hardness Up to 7 Mohs
Heat resistant Up to 300 C
Chemical resistant pH 2 – pH 13

Glass Substrate X
18
In contrast, Nanovations products create an ultra thin coating by covering and penetrating the Nano scale surface structure and pores of the glass.
Glass Substrate
19
With the Nanovations range of products, the dirt has a significant smaller contact area with the substrate. Adhesion is low, dirt can be removed without much force. The surface is easy to clean.
Glass Substrate

Dirt
On conventional coatings the contact area towards the surface is much larger . Easy to clean effect is provided via a non stick chemical and not via a reduction in contact area.
20
Dust accumulation is significantly reduced when the surface has been treated.
Uncoated Coated with NG 1314
21
In situations where dust and dirt cannot be removed via wind action or ,exposure to clean rain, rinsing with clean water will remove large portions of the dirt and dust contaminations.

Project: Pinnacle Apartment Milsons Point
• Connell Mott MacDonald’s
project for Multiplex, Sydney.
The Pinnacle is the first
high rise building in the world
where a nanotechnology glass
protection system was used
on the complete building
to prevent glass contaminations.

Profile
About Nanovations: The business was established in 2002. In 2006 the group R&D and manufacturing operation was combined under the Nanovations brand. The team of Nanovations is now the only manufacturer of colloidal silica sol gel coatings for glass, in the southern hemisphere. In 2005, the founding team members won an award for the best new product at the DesignEX Tradeshow in Sydney. In 2006 the first high rise building in the world was coated with Nanovations glass coatings. Some of the buildings treated in the past, are among the longest serving Nano coated glass surfaces on the market. Exposed to the harsh Australian environment, the coatings have proven their reliability for over 10 years. No other company can offer such a track record. Nanovations collaborates with global companies, research partners and universities for R& D to develop new markets in this area of growth.
