The company, a spinoff from the Ministry of Defence in 2004, makes repellent coatings that are used in a wide number of areas, including electronics, industrial filters and military clothing. Its Aridion coating for electronic equipment is used to protect hearing aids and batteries from water damage, reducing equipment failure caused by rain, high humidity and accidental wearing in the shower.
The funding has come from existing shareholders, Naxos Capital Partners, Swarraton Partners, Porton Capital, Unilever Ventures and Rainbow Seedfund.
"We are now really beginning to gain momentum, with our world leading liquid repellent nano-technology being used by a range of customers in a range of high volume products around the world," said Carl Francis, Chief Executive of P2i.
"The jump in royalty revenue is a clear indication of our prospects as our customers' ramp up the usage of our technology. We have also signed another six key multi-year licensing agreements across four sectors, which not only bodes well for our prospects but importantly widens our industry sector exposure.
P2i's technology works by applying a nanometre-thin polymer layer over the entire surface of a product. Using an ionised gas this layer is molecularly bound to the surface and will not leach away, giving better gives oil and water repellency by reducing the surface energy to one third that of PTFE (polytetrafluoroethylene).
