AkzoNobel Interpon Shines At The Shard Inauguration

By: Tim Pennington 5. October 2012

 
AkzoNobel is showcasing its Interpon powder coatings on the newly inaugurated Shard tower in London, a new development in the London Bridge quarter that is now the tallest building in Western Europe.
 
AkzoNobel says the new building has coating protection from eight different Interpon products applied by approved applicators Josef Gartner and Höfer and SAS International (UK).
 
Interpon D1036 and Interpon 810 coatings are protecting and decorating the interior ceiling panels, while products from the Interpon D2525 range offer superior protection to the exterior aluminium structure.
 
“We are very proud that our coatings have been chosen for this prestigious project,” says Russell Deane, Global Architectural Marketing Manager AkzoNobel Powder Coatings. “The Shard tower is already an iconic structure in the London skyline so expectations for product performance were high. We are delighted that our products stood out as the coating of choice on this project.”
 
Interpon D is a range of sustainable powder coatings developed specifically for the architectural and construction industry. The Interpon D range has been used on a wide range of iconic, world-class structures from sports stadiums to museums, apartment buildings, hotels and offices.
 
The Shard combines office space, luxurious apartments, outstanding restaurants and the prestigious Shangri-LA hotel, towering at 310 meters. We are pleased to add the Shard to our world-wide track record.

 

 

New Surface Coating Evicts Biofilms For Good, Researchers Say

By: Tim Pennington 10. August 2012

The word "SLIPS" is coated with the SLIPS technology to show its ability to repel liquids and solids and even prevent ice or frost from forming. The slippery discovery has now been shown to prevent more than 99% of harmful bacterial slime from forming on surfaces. (Image courtesy of Joanna Aizenberg, Rebecca Belisle, and Tak-Sing Wong.)

 

Biofilms may no longer have any solid ground upon which to stand. A team of Harvard scientists has developed a slick way to prevent the troublesome bacterial communities from ever forming on a surface. Biofilms stick to just about everything, from copper pipes to steel ship hulls to glass catheters. The slimy coatings are more than just a nuisance, resulting in decreased energy efficiency, contamination of water and food supplies, and—especially in medical settings—persistent infections. Even cavities in teeth are the unwelcome result of bacterial colonies.

 

In a study published in the Proceedings of the National Academy of Sciences (PNAS), lead coauthors Joanna Aizenberg, Alexander Epstein, and Tak-Sing Wong coated solid surfaces with an immobilized liquid film to trick the bacteria into thinking they had nowhere to attach and grow.

 

“People have tried all sorts of things to deter biofilm build-up—textured surfaces, chemical coatings, and antibiotics, for example,” says Aizenberg, Amy Smith Berylson Professor of Materials Science at the Harvard School of Engineering and Applied Sciences (SEAS) and a Core Faculty Member at the Wyss Institute for Biologically Inspired Engineering at Harvard. “In all those cases, the solutions are short-lived at best. The surface treatments wear off, become covered with dirt, or the bacteria even deposit their own coatings on top of the coating intended to prevent them. In the end, bacteria manage to settle and grow on just about any solid surface we can come up with.”

 

Taking a completely different approach, the researchers used their recently developed technology, dubbed SLIPS (Slippery-Liquid-Infused Porous Surfaces) to effectively create a hybrid surface that is smooth and slippery due to the liquid layer that is immobilized on it.

 

First described in the September 22, 2011, issue of the journal Nature, the super-slippery surfaces have been shown to repel both water- and oil-based liquids and even prevent ice or frost from forming.

 

“By creating a liquid-infused structured surface, we deprive bacteria of the static interface they need to get a grip and grow together into biofilms,” says Epstein, a recent Ph.D. graduate who worked in Aizenberg’s lab at the time of the study.

 

“In essence, we turned a once bacteria-friendly solid surface into a liquid one. As a result, biofilms cannot cling to the material, and even if they do form, they easily ‘slip’ off under mild flow conditions,” adds Wong, a researcher at SEAS and a Croucher Foundation Postdoctoral Fellow at the Wyss Institute.

 

Aizenberg and her collaborators reported that SLIPS reduced by 96–99% the formation of three of the most notorious, disease-causing biofilms—Pseudomonas aeruginosa, Escherichia coli, and Staphylococcus aureus—over a 7-day period.

 

The technology works in both a static environment and under flow, or natural conditions, making it ideally suited for coating implanted medical devices that interact with bodily fluids. The coated surfaces can also combat bacterial growth in environments with extreme pH levels, intense ultraviolet light, and high salinity.

 

SLIPS is also nontoxic, readily scalable, and—most importantly—self-cleaning, needing nothing more than gravity or a gentle flow of liquid to stay unsoiled. As previously demonstrated with a wide variety of liquids and solids, including blood, oil, and ice, everything seems to slip off surfaces treated with the technology.

 

To date, this may be the first successful test of a nontoxic synthetic surface that can almost completely prevent the formation of biofilms over an extended period of time. The approach may find application in medical, industrial, and consumer products and settings.

 

In future studies, the researchers aim to better understand the mechanisms involved in preventing biofilms. In particular, they are interested in whether any bacteria transiently attach to the interface and then slip off, if they just float above the surface, or if any individuals can remain loosely attached.

 

“Biofilms have been amazing at outsmarting us. And even when we can attack them, we often make the situation worse with toxins or chemicals. With some very cool, nature-inspired design tricks we are excited about the possibility that biofilms may have finally met their match,” concludes Aizenberg.

 

Aizenberg and Epstein’s coauthors included Rebecca A. Belisle, research fellow at SEAS, and Emily Marie Boggs ’13, an undergraduate biomedical engineering concentrator at Harvard College.

NASF Hosts Chinese Finishing Association for EPA Meetings

By: Tim Pennington 1. August 2012

 
The NASF in June hosted leaders of the Chinese finishing industry for discussions with U.S. regulators on environmental regulatory challenges and the future of standard-setting for the two countries.
 
U.S. finishers invited the Chinese delegation earlier this year as part of the NASF SUR/FIN international panel discussion in Las Vegas, and the launch of the NASF’s Global Surface Technology Roundtable.
 
The U.S.-China coatings exchange on standards and environmental sustainability spanned meetings from Washington to Los Angeles, where NASF’s California chapter hosted the Chinese delegation for a tour of the Los Angeles County Sanitation District.
