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.

Other features and benefits include:

  • 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

Gluten Free

Indications for Use

Porcelain Etch is designed for intraoral or extraoral porcelain etching. Use it to etch porcelain or old macrofilled composites prior to bonding.

Preparing the Porcelain

– See Instructions for Use for complete instructions, warnings, and precautions.

  1. Etch clean bonding surface with Porcelain Etch for 90 seconds, rinse, and dry.

Viscous, Buffered 9% Hydrofluoric Acid

Porcelain Etch is a buffered, gelled hydrolic acid designed specifically to etch fractured dental porcelain and etching porcelain veneers, crowns, or inlays. It can also be used for etching porcelain crowns before bonding orthodontic brackets. It is buffered and gelled to minimize any irritation that could occur from the hydrofluoric acid vapor.

Etch is Easy to Control and Place

Porcelain Etch features a high visibility yellow hue so you can see exactly where it is placed. It is also viscous enough to stay where you place it.

Designed to Work Together

Porcelain Etch and Silane are designed to be used together when etching porcelain to provide high porcelain-to-resin bond strengths. When used with a high-quality bonding resin, Porcelain Etch and Silane can produce one of the highest porcelain-to-resin bond strengths compared to other porcelain bonding products.1

Q: When should I use Porcelain Etch and Silane?

A: Porcelain Etch and Silane can be used for etching porcelain, lithium disilicate, lithium silicate and other silica-based materials. It is not indicated for use with zirconia.

Q: Will the Porcelain Etch stain composites or resin cements?

A: ​No, Porcelain Etch is a predictable, stain-free chemistry designed to give high visibility without discoloring materials.

Q: Can Porcelain Etch be used intraorally?

A:​Yes! Porcelain Etch is ideal for use with intraoral porcelain etching, but a rubber dam or EtchArrest must be used to protect nearby tissue and restorations.
