Water damage in mobile phones could no longer be a worry with new coating tech

P2i will launch its new waterproof coating solution Dunkable at the Mobile World Congress - and says it will prevent water damage in fully submerged mobile phones

Water seeping into a mobile phone might not have to spell the end for handsets anymore as new protective coating technology was launched.

Liquid protection expert P2i says its Dunkable waterproofing solution enables a smartphone to operate normally even when the outer case has been breached and it has been fully submerged for long periods.

It claims the interior coating, which is customised for particular devices and protects all the core components such as electronics inside a phone, is the most advanced on the market.

The Oxford-based company will give the first demonstration of the innovation at next week’s Mobile World Congress in Barcelona by dunking Dunkable-treated handsets in water tanks.

P2i CEO Ady Moores said: “Dunkable is a world-first and represents a step change in the level of waterproofing available to handset manufacturers.

“The launch means that for the first time, original equipment manufacturers (OEMs) have access to the most advanced water protection capabilities that can be rolled out on virtually all form factors – not just the usual square designs.

“Its launch marks the next generation of ‘Protected by P2i’ products, where we will have the ability to treat over half a billion smartphones in 2019 alone.”

How P2i Dunkable prevents water from damaging mobile phones

P2i says Dunkable uses a patented “multi-chemistry approach” customised to an OEM’s manufacturing process and handset device.

The coating is said to be inert and doesn’t degrade through impact, heat or “environmental stress” – or when in contact with solvents.

The coating can protect a smartphone to IPX8 level for the life of the device, says the company.

This is a variable waterproofing grade agreed between a manufacturer and the International Electrotechnical Commission (IEC), but typically means devices can survive for longer than 30 minutes at a depth of more than 10ft.

According to P2i, mechanical seals currently used to protect handsets to IPX7 and IPX8 levels only act as a barrier to water, allowing devices to be short-circuited if water enters via a cracked screen or de-laminated seal

They also use space that could accommodate larger batteries, which will be essential for managing the power demand of 5G modems.

In a statement, the company added: “Dunkable enables handset manufactures to create a competitive edge through bold, flexible designs that are thinner, foldable, or have smaller bezels – without compromising the water protection.”

P2i will initially target Dunkable at smartphones but the technology is also applicable to tablets, wearables and consumer devices, as well as industrial systems.

The first mobile protected by the coating is expected to be released this year, although its identity has not yet been revealed.

 

Water damage in mobile phones one of consumers’ biggest concerns

Recent surveys have placed waterproofing and durability among the top of consumers’ demanded features on a smartphone.

A 2016 YouGov poll of US consumers ranked waterproofing as third most in-demand feature; a 2017 Morning Consult and Statista survey ranked it as the most important feature; and a 2018 Morning Consult and Statista poll stated 88% of phone buyers believe durability – listed as waterproofing and shatter-proof screens – is “vital”.

Research by market analyst Canalys also shows the average handset lifespan will rise by 16% in North America and 5% in Europe and the Asia-Pacific region between 2017 and 2022.

P2i said this is due to increasing handset costs, rising environmental awareness among consumers – but this trend means more robust and longer-lasting waterproof features are “paramount”.

Advanced water protection technologies also reduce the cost of refurbishing, allowing more manufacturers to access the refurbished phone market, which market intelligence firm IDC estimates will grow from $19bn (£15bn) in 2017 to $52bn (£40bn) in 2022.
