The only material that Sonihull does not protect from bio-fouling is wood.
The system relies on internal resonance to transmit the ultrasonic signals to the surface being protected.
Compared to man-made materials, wood is full of varying densities and voids and is not an efficient transmitter of ultrasound.
Sonihull ECO provides effective anti-fouling protection for solid materials, including Steel, Stainless Steel, Aluminium, GRP, FRP, Kevlar, Titanium and rigid plastics.
Note – The protection of certain concrete and ferro-cement structures will depend on their individual composition.
Silicone-based coatings are known to dampen up to 40% of ultrasonic signals and will reduce system effectiveness.
