A new self-cleaning extrusion coating which uses natural rainfall to help remove dust and stains from
exterior walls has been launched by AkzoNobel (coilcoatings.akzonobel.com/) in China.
The TRINAR® SC Series was developed specifically to support the country’s urban renewal. The new
coating will address demand in the high-end building market for products capable of protecting
buildings that have complex curved surfaces and irregular architectural forms.
The coating features hydrophilic self-cleaning technology and is certified to the international AAMA
2605 weatherability standard. So as well as offering long-lasting surface protection, the coating also
retains a pristine, like-new façade appearance over time, notes a press communiqué from the
company.
“This is a significant innovation which will enable customers to unlock the long-term value of self-
cleaning technology, with no changes to existing customers’ coating lines – and zero compromise on
color selection or finish texture,” explains James Kavanagh, Commercial Director of AkzoNobel’s Coil
and Extrusion business.
He adds that by reducing the frequency of manual high-rise cleaning procedures, the next
generation coating can contribute to lowering operation and maintenance costs across a building’s
entire lifecycle. It can also help reduce the amount of water, chemicals and maintenance resources
typically associated with cleaning building exteriors. This makes it ideally suited for the construction
requirements of irregular curtain wall geometries, as well as supporting more sustainable building
operations over time.
The factory-applied TRINAR SC Series will help the construction industry meet the new operational
and maintenance challenges brought about by China’s ongoing pursuit of premium building quality.
To help achieve striking design impact, many high-end commercial buildings feature complex curved
surfaces and irregular architectural forms, which makes façade cleaning and upkeep far more
technically demanding.
