Potable water tank paint is used for internal corrosion protection of ship potable water tanks, domestic water tanks and tap water storage tanks. Its key particularity is that it must pass sanitary safety certification (in China, GB/T 17219 Safety Evaluation Standard for Equipment and Protective Materials in Drinking Water Supply and Distribution; for ships, classification society and relevant international specifications also apply), the cured film shall not release harmful substances into the water and shall not affect water quality or taste. The mainstream is sanitary-grade epoxy coatings (solvent-free or high solids, avoiding solvent residues). Selection covers three points: whether a valid sanitary permit or test report is held, the applicable temperature range (whether hot water tanks are involved), and post-application curing and flushing requirements — most products require flushing to procedure after curing and water quality testing before commissioning. This page compiles OEM data for potable water tank coatings from various brands.
