Copper was discovered nearly 7000 years ago and the first mines were operated on the Cyprus island, which gives its name to the metal. Fifteen centuries before Christ, the Phoenicians, seamen and trader people, had a major technological advantage in boat construction. One of their innovations comprised fixing copper plates on hulls to protect them and improve their manoeuvrability.
It is also said that a few centuries later, Nelson won the Battle of Trafalgar owing to this type of cladding, which enabled his boats to be faster than those of the French fleet, which was not equipped with this technology and was handicapped by the colonies of molluscs on its exterior hulls.
The principle lies at the level of the copper atom, which releases ions that paralyse the respiratory system of microorganisms and destroys them. Then, oxidation transforms the state of the copper, which end up scattering and moves on to becoming a new atom, and so on and so forth...
Needless to say, we are talking about extremely low quantities of dispersed copper, since the average leaching rate of the M300 is about 4.5 µg/cm2/day. This means that, in order to “exhaust" the M300 on an area of 1cm2, with the coverage ratio of 450g/m2 allowed by a standard kit, it should take an average of 27 years.
A non-conductive composite
The specific hybrid resin polyester that structures the M300, when combined with the hardener, creates an encapsulation of the copper particles that insulates the "grains" from each other and facilitates a high adhesion to the frame. Owing to the resin between the copper particles, the electrical conduction is stopped, thus leaving no room for any phenomenon of electrolysis.
