PrimaDry drying agent contains 99% organic solvents and 1% primer and is optimal for pit and fissure drying and preparation. It rapidly volatilizes moisture content of pits and fissures and microcracks of existing restorations following the etching process. The ultrafine primer film allows UltraSeal XT® plus sealant or PermaSeal sealer to flow perfectly into every pit and fissure. Also useful prior to placing composite repairs. Do not use on dentin! 1.2ml syringes.
