Neptune HRT water-based antifouling uses the latest technology available to create a hybrid paint film strong enough to handle the tough marine environment. Hybrid Reactive Technology features high density biocide utilization to maximize effectiveness by using biocide more effectively along with film modifiers to reduce yearly build-up, maintain uniform color consistency, and lower weight while providing a smoother finish than traditional paints. Soap and water cleanup along with no strong solvent smell, yields a user-friendly application. Neptune HRT does not require sanding between coats saving time and money. With low VOC it's ideal for marinas under restrictions. Neptune HRT can be used over all previously painted surfaces.
