Ultradent 90-second Porcelain Etch is used to etch porcelain veneers, crowns, bridges, inlays, onlays, and fractured dental porcelain. Ultradent 60-second Silane is used after hydrofluoric acid etching to prepare the surface for bonding resin.
Studies have demonstrated that Silane, when used with Porcelain Etch and a quality bonding resin, yields the highest bond strength to porcelain when compared with other porcelain bonding products.¹  Both Porcelain Etch and Silane may be used intraorally or extraorally.

• Porcelain Etch is a viscous, buffered 9% hydrofluoric acid
• Etch is easy to control and place
• Will not stain composite or resin cement
• Silane is a single-component solution
• Yields highest porcelain-to-resin bond strengths¹
• Porcelain Etch and Silane may also be used on lithium disilicate (IPS e.max^®2 ) restorations
