Ultradent Porcelain Etch is a viscous, buffered 9% hydrofluoric acid. Porcelain Etch is designed for intraoral or extraoral porcelain etching.Use it to etch porcelain or old macrofilled composites prior to bonding and repair. Also use it when in-office etching of indirect restorations,such as veneers.
Etch is easy to control and place. Will not stain composite or resin cement. Yields highest porcelain-to-resin bond strengths.
