Porcelain Etch Kit, 90 Second, 9% Hydrofluoric Acid

Clinical Overview

Ultradent Porcelain Etch is a buffered, gelled 9% hydrofluoric acid etchant formulated for efficient conditioning of fractured or intact silica-based ceramic restorations—including veneers, crowns, bridges, inlays, and onlays—in just 90 seconds. Its viscous, yellow-tinted formulation provides precise placement and visible control, and it does not stain composite or resin cement.

Key Benefits

• Efficient 90‑second etch: Produces ideal surface micro-roughness for bonding in under two minutes.
• Buffered hydrofluoric gel: Minimizes vapor irritation; maintains precise adhesion without drip.
• High visibility gel: Yellow tint helps clinician accurately place and limit contact.
• Compatible with silane bonding: When combined with Ultradent Silane, yields among the highest porcelain‑to‑resin bond strengths.
• No staining risk: Safe for use on restorations without discoloring cements or composites.
• Gluten‑free certification: Safe for patients with dietary sensitivities.

Kit Contents

• 2 × 1.2 mL syringes of Porcelain Etch gel (≈1.3 g each)
• 2 × 1.2 mL syringes of Silane coupling agent (for surface priming post‑etch)
• 20 × Black Mini Brush tips and 20 × Inspiral Brush tips for etch and silane application
• Instructions for use leaflet

Working & Setting Times

• Etch time: 90 seconds on porcelain or silica-based surfaces
• Rinse and dry: Thorough rinsing following etching removes acid residues and prepared salts
• Silane dwell time: Apply Silane to etched surface and allow to react for 60 seconds. Do not rinse before bonding resin application

Indications

• Etching of porcelain-based restorations prior to adhesive resin bonding
• Preparation of fractured or chipped porcelain surfaces for chairside repairs
• Bonding orthodontic brackets onto porcelain crowns or veneers
• Use intra‑orally or extra‑orally with appropriate isolation (e.g. rubber dam, EtchArrest) to protect tissues

Instructions for Use

1. Isolate the operative area thoroughly with rubber dam or EtchArrest barrier.
2. Apply Porcelain Etch gel using Inspiral Brush tip, gently painting over porcelain surface only.
3. Allow etchant to remain in contact for exactly 90 seconds.
4. Rinse thoroughly with water to remove all acid residues and etched debris; dry surface completely.
5. Optional: apply 5 seconds of Ultra‑Etch phosphoric acid to remove residual salts, rinse and dry.
6. Attach Black Mini Brush tip and apply Silane to etched surface; allow to dwell for 60 seconds, then gently air‑dry—do not rinse.
7. Proceed immediately with adhesive resin cement per manufacturer protocol.
8. Discard single-use tips and acid contact surfaces as per safety protocols. Wear appropriate PPE.

Summary

Ultradent Porcelain Etch Kit (Ref. 405) delivers a precise, buffered 9% hydrofluoric acid gel optimized for 90‑second etching of porcelain and silica-based restorations. Its high visibility, gel viscosity ensures controlled placement, while combined use with Silane produces strong, reliable porcelain‑to‑resin bonding. Safe, effective, and gluten‑free, this kit supports clinical efficiency in porcelain repair and adhesive bonding workflows.
