Prime-Blend® Ultra is a unique light-cured, radiopaque, dentin adhering liner and base material containing calcium hydroxide and calcium hydroxyapatite in a urethane dimethacrylate (UDMA) base. It is a highly filled resin (for a liner) with minimal shrinkage and water absorption.

Prime-Blend® Ultra has a higher viscosity then conventional liners, eliminating the need for a ball-type applicator. It’s superior strength and water insolubility (it won’t leach out) make Prime-Blend® Ultra the material of choice under composite, amalgams, gold and ect.

Prime-Blend Ultra® is easily contoured with high and low speed hand pieces. No more instrument-to-pad-to-mouth delivery. No more contamination of cavo-surface margin upon entry into cavity preparation.
