PermaFlo DC from Ultradent is a highly filled, small particle, dual-cured luting resin. Because of its resin design and thixotropic properties, PermaFlo DC has the lowest film thickness (9 μm) known for a luting composite resin.
Its unique formulation provides maximum strength and minimal wear. PermaFlo DC is indicated for use as an initial layer and/or bulk fill for posterior bonded composites.
