More than 40 years ago, Flexdel Corp. developed the first completely water-based copolymer ablative paint, Aquagard. Today, Aquagard goes beyond compliance with EPA standards for VOCs and has become a player in the environmentally friendly bottom-paint market. Aquagard utilizes cupreous oxide as its biocide but has developed technology to control leach-out rates. Aquagard requires less copper, but offers year-round antifoul protection. Being water-based, it is easily rolled or brushed and flows out evenly for a smooth finish. It can be applied directly over other hard bottom paints, and it will not streak from rainwater. It cleans up with soap and water, and, with its low VOCs, can be applied indoors in the off-season.
