PPG(NYSE: PPG) announced the launch of PPG SIGMAGLIDE® 2390 marine coating, 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.
The biocide-free fouling release coating is based on revolutionary PPG HydroReset™ technology, which 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.
Based on third-party evidence following ISO 19030 and International Towing Tank Conference(ITTC) standards, 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. Actual performance will depend on ship model and operating conditions.
PPG Sigmaglide 2390 coating can help owners and operators to meet targets for reduction of greenhouse gas emissions under the International Maritime Organization’s energy efficiency(EEXI and EEDI) and carbon intensity(CII) requirements, which went into effect this year.
The exceptional fouling control performance of PPG Sigmaglide 2390 coating is achieved with no release of biocides into the oceans.
PPG Sigmaglide 2390 coating is also suitable for electrostatic application, which provides high transfer efficiency, leading to lower paint consumption. In service, the coating can deliver up to 150 days of idle performance and an extended lifetime of more than 10 years with minimal maintenance requirements. These benefits, combined with the power savings, provide an industry-leading return on investment for shipowners.
