Recently launched onto the marine market, PPG Sigmaglide 2390 aims to help ship owners lower power consumption and carbon emissions and meet demands for higher performance with no adverse impact on the marine environment.
The biocide-free fouling release coating is based on PPG HydroReset technology, which modifies the coating when it is immersed in water to create what is described as “a super-smooth, almost friction-free surface that marine organisms do not recognise and cannot adhere to.”
According to PPG, this coating enables vessels to maintain a clean hull and reduce drag, achieving power savings of up to 20%, a speed loss performance of less than 1%, and up to 35% reduction in CO2 emissions in comparison to traditional antifouling coatings. PPG Sigmaglide 2390 is also suitable for electrostatic application, which provides high transfer efficiency, leading to lower paint consumption. In service, PPG says the coating can deliver up to 150 days of idle performance and an extended lifetime of more than 10 years with minimal maintenance requirements.
