A clear resin that penetrates and seals margins and the microporosities and cracks in composite restorations. Provides a smooth finish, eliminates the final polishing steps, bonds in a slightly moist field, and does not alter the anatomy or occlusion of the tooth, or discolor the restoration. Forms a close association with tooth structure and integrates with the tooth in a way that is unique for a dental resin, resulting in a positive seal and a smooth margin that is better adapted to the anatomy of the tooth.
