Peelable Nano Tech Coating Protects Windows

WEDNESDAY, JULY 3, 2024


Hong Kong property developer Chinachem Group has partnered with local research and development center Nano and Advanced Materials Institute to further develop an interior and exterior peelable protective nanocoating for windows.

According to the release, the patented coating is expected to improve costs and environmental effectiveness in construction.

About the Coating

Glass is prone to damage, leading to a loss rate of as high as 30%, Chinachem says. Contractors can wrap the glass with foam boards, but this provides low light transmittance and requires additional indoor lighting during the construction stage. Traditional adhesive protective coatings also may adhere to the glass firmly and need to be cleaned thoroughly.

One of the benefits of the new technology, the companies say, is the ability to adjust the degree of protection according to the needs of various construction conditions. The coating’s thickness reportedly exceeds traditional protective materials’ thickness by more than three times.

This offers protection to reduce cracked or damaged glass windows during property handover and inspection, minimizing the need for glass replacement

Additionally, the nanocoating is ultraviolet- and water-resistant to ensure there is no residue formed on the glass even after prolonged exposure to sunlight or rain. It can also be applied to a variety of substrates, including metal surfaces and treated wooden furniture.

In terms of sustainability, the coating reportedly reduces construction waste since it is a single layer that still provides protection without the need for additional foam board wrapping. It is also easily removable and reusable.

Chinachem and NAM add that the formula is solvent-free, preventing the release of volatile organic compounds. The nanocoating reportedly helps conserve energy by allowing natural light to pass through the glass.

“We are strongly committed to driving green real estate technology advancements through collaboration with scientific research institutions,” noted Donald Choi, Executive Director and CEO of Chinachem Group. “Having successfully adopted Modular Integrated Construction (MiC) for private residential projects, we have now partnered with NAMI to develop this Peelable Nano Protective Coating technology.”

Choi added that they plan to implement the coating in upcoming development projects in Tai Po Kau and Tung Chung.

“This Peelable Nano Protective Coating improves the protection of building materials and helps reduce construction waste and carbon emissions,” explained Dr. Ivan Sham, Chief Commercial Officer of NAMI.
