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 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


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


Viscous, Buffered 9% Hydrofluoric Acid:

  • Porcelain Etch is a buffered, gelled hydraulic 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

Direction to use 


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

STEP 2: CLINICAL TIP: Apply phosphoric acid (Ultra-Etch®) for five seconds to remove porcelain salts and debris formed by hydrofluoric acid etching. Rinse and air dry.

STEP 3: ​Apply a puddle coat of Silane to the inside surface for 60 seconds, dry, and set the prosthesis aside. Do not rinse.


When to use Porcelain Etch?

  • 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

Will the Porcelain Etch stain composites or resin cements?

  • No, Porcelain Etch is a predictable, stain-free chemistry designed to give high visibility without discoloring materials

Can Porcelain Etch be used intraorally?

  • 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
