Our silylated acrylate technology works by seawater penetrating the outer layer, starting chemical hydrolysis. As the level of hydrolysis rises, the polymer starts to become soluble forming a very thin leach layer and releasing the biocide. Because silylated acrylate film is relatively impermeable, water only penetrates the first few microns of the coating so that only a few microns undergo hydrolysis at a given time. The result is a highly stable and predictable polishing rate for the docking period.
The leach layer is progressively eroded from the surface, exposing a fresh coating layer underneath.
Special microfibres reinforce the binder, providing a skeleton effect that gives the coating enhanced mechanical strength and makes it more resistant to cracking and peeling.
