The 5G Blocking Paint that disappeared TEN YEARS AGO.

Updated: Dec 25, 2019

The original article below featured in New Scientist magazine in January 2009. The article by Colin Barras was titled "Cheap paint could protect against super-fast wireless"

"As wireless communications become faster, it’s not just older, slower devices that are left behind. The shielding that protects sensitive electronic equipment like that used in hospitals is becoming increasingly obsolete as new, higher frequencies are used to send data.

Now Japanese researchers have come to the rescue with a new metal-rich coating designed to protect newly vulnerable devices. The development is timely: while the latest wireless communications use electromagnetic waves with a frequency of over 100 gigahertz, the best wave absorbers commercially available are effective only up to around half that.

The 120 GHz band, for example, can send data at up to 10 gigabits per second. That’s fast enough for the real-time transmission of uncompressed video in high-definition TV format, and rivals the speed of the fastest wired local area networks.

Iron constitution

The ability to block electromagnetic (EM) waves comes about when a material’s magnetic field resonates at the same frequency as the wave. Wave absorbers are usually made from iron-rich oxides, but higher-frequency transmissions outstrip the power of iron to absorb electromagnetic waves.

However, the standard oxide coating – which contains barium as well as iron – has a maximum resonance frequency that is outstripped at 48 GHz.

Shin-ichi Ohkoshi’s team at the University of Tokyo in Japan has just identified a new aluminium-iron oxide able to block waves with a frequency almost four times higher.

The team used a sensitive magnetometer to confirm that a powder of the new oxide can absorb EM waves of up to 182 GHz at room temperature.

Protective paint

The composition of the new material somehow distorts the bonds between iron and oxygen from their usual shape, which the team believes explains the material’s magnetic properties. Learning more about this effect may make it possible to identify new metal oxides that can absorb EM waves at even higher frequencies.

Particles of the new material could be incorporated in a paint to shield sensitive equipment in medical areas, labs, or aeroplanes from the effects of high-speed wireless communications, says Ohkoshi, who adds that the paint would be relatively cheap to make because aluminium and iron are abundant materials.

“We collaborated with DOWA Electronics, a Japanese industrial company [to make a 100-kilogram sample order],” says Ohkoshi. “The manufacturing cost is very cheap – around £10 ($14) per kg.”


... and so the article ended with no doubt some 'New Scientist' readers at that time expecting this new and clever product to be soon released to market, however that was the last that the internet , the world or Mr Ohkoshi had to say on the matter and the paint and now with the looming threat of increasing Ghz wavelengths invading our spaces nearly 11 years has lapsed since the promises of the article.

You must reflect that while it is easy to search the internet and find paint that will block EMF and wifi , these are mostly carbon based products will low Ghz absorption ability. and this is reflected in statements by the manufacturers as to the efficacy of the paints and the wavelengths that they can protect against. "99% Efficiency at 6GHz!" (not an affiliate link we do not necessarily recommend this product - do your own research )

You may even be aware of T98 paint , but even this will only protect up to 10Ghz

As highlighted in the New Scientist article Mr Ohkoshi's paint had stated Ghz absorption abilities up to 182 Ghz at room temperature.... more than enough to absorb the 5G wavelengths that we are hearing talked about as becoming common place. It was in effect a 5G Protection Paint.

According to internet searches Shin-ichi Ohkoshi is still connected with the University of Tokyo and it appears he now has his own laboratories Yes I'll say that again , his paint hasn't come to market but he now has a laboratory named after him and several prestigious awards to his name.

I tracked down a contact email address for him and last October (2018) I wrote to Mr Ohkoshi directly and respectfully to enquire what had happened to his paint. The New Scientist article of 2009 had seemed so confident not only in the tested benefits of this paint but also of its relatively imminent release to market. Now I don't know whether Mr Ohkoshi understands English , I certainly have zero Japanese vocabulary , but I am certain that his position at the University of Tokyo would allow him access to colleagues that do, in other words I am fairly certain ,instinctively and intuitively that my email has been read. That being said, at the time of this article, over a year later, I am yet to receive a reply to my question as to why this paint is not available now.

It strikes me as curious that such a well researched , thoroughly tested and now ten years later wholly useful and frankly much needed product has not been made generally and readily available. This is more so curious given that it has been developed at a well respected institute of learning and by a well respected team of researchers , chemists and scientists who foresaw a problem with increasing frequencies of electromagnetic waves and the densification of these waves.

My curiosity as to the disappearance of this paint is especially peaked when I also consider that Mr Okoshis team had managed to develop a product that would cost as little as $14USD a litre to produce.... making it very accessible to many many people choosing to protect themselves , their loved ones and their homes from the unique non native EMF'S and non-ionising radiation ever increasingly proliferating our spaces. You can draw your own conclusions as to why a tested paint product, successfully developed and designed specifically to combat the higher and denser frequencies of wireless radiation from the proliferation of 5G has not made it to market, or why the inventor has not pushed for it to be ....
