2K high build epoxy primer. Used for hull protection in paint processes on steel, aluminium and gelcoat boats. It offers a very good barrier to water and it can be used on the ship’s bottom (under the waterline) as well as on topside (above the waterline). Especially suitable to insulate the filler, it allows to obtain a high protection level with a limited number of coats. On fibreglass boats it avoids osmosis formation and it favours antifouling adhesion.
