“Sigmaglide 2390 fouling release coating has a super-smooth, near friction-free surface when immersed in water” –PPG
PPG (NYSE: PPG) has launched a biocide-free fouling release coating that, it says, uses a breakthrough approach to help shipowners lower power consumption and carbon emissions and meet demands for higher performance with no adverse impact on the marine environment.
Called PPG Sigmaglide 2390, the coating is based on PPG’s HydroReset technology. This modifies the coating when it is immersed in water to create a super-smooth, almost friction-free surface that marine organisms do not recognize and cannot adhere to.
This almost certainly a PPG news release, but if true, it is potentially very significant. Let’s hope so.
