The Boero Defender Bi-Component Epoxy Antifouling Primer is a high-performance, two-component epoxy primer designed to provide exceptional anti-corrosive and anti-osmosis protection for boat hulls, outboards, and superstructures. Its advanced formulation includes mica platelets that form a layered barrier within the coating, enhancing its protective properties. The primer can be applied as a multi-purpose primer and as a bonding coat for antifouling systems. Notably, it allows for sanding-free overcoating for up to three months, offering flexibility in application. The Defender Primer is available in 0.75 L and 2.5 L formats and can be applied by brush, roller, or airless spray.
