Bisco Porcelain Etchant 4% HF Gel

• Active Ingredient: Hydrofluoric Acid (HF) at 4% concentration
• Form: Gel
• Viscosity: Controlled for precise application
• PH Stabilization: Buffering agents are included to minimize acidity
• Color: Typically includes coloring agents for visibility
• Storage Temperature: Room temperature (20°C/68°F - 25°C/72°F)
• Application: Designed for etching porcelain surfaces to enhance bonding with resin cements

Preparation:

• Ensure that the work area is clean and well-ventilated.
• Wear appropriate protective gear, including gloves and eye protection.
• Prepare the porcelain surface by cleaning it thoroughly to remove any debris, stains, or contaminants.

Application:

• Dispense a small amount of the 4% HF Gel onto a clean mixing pad or directly onto the porcelain surface using the provided applicator tip.
• Apply a thin, even layer of the gel to the porcelain surface that needs to be etched.
• Ensure that the gel covers the entire area to be bonded. Avoid spreading the gel beyond the intended area.

Etching Time:

• Allow the gel to remain on the porcelain surface for 60–90 seconds. Refer to the product’s specific instructions for the recommended etching time.
• Do not exceed the recommended etching time to avoid over-etching or potential damage to the porcelain.

Rinsing:

• Thoroughly rinse the etched surface with water to remove all traces of the gel.
• Use a strong water stream or air-water syringe to ensure complete removal of the gel.

Drying:

• Gently dry the porcelain surface with air or a clean, dry cloth.

Post-Etching:

• Apply a silane coupling agent to the etched porcelain if recommended, according to the manufacturer's instructions.
• Proceed with the bonding process using the appropriate resin cement.

Cleanup:

• Dispose of any used materials and clean the work area.
• Store the remaining gel in a cool, dry place, following the manufacturer's storage recommendations.

• 4% Hydrofluoric Acid: Provides effective etching of porcelain surfaces, increasing surface roughness for improved bonding.
• Gel Consistency: Offers precise control and application, minimizing the risk of over-etching or spreading to unintended areas.
• Enhanced Bonding: Improves mechanical retention by microscopically roughening the porcelain, leading to stronger adhesive bonds with resin cements.
• Quick Etching Time: Typically 60–90 seconds is enough for optimal surface preparation.
• Versatility: Suitable for a wide range of porcelain restorations, including crowns, veneers, inlays, onlays, and repair of fractured restorations.
• Easy Rinsing: Rinses off easily with water, ensuring a clean surface ready for bonding.
• Controlled Application Tips: Comes with applicator tips for accurate placement, especially in delicate or hard-to-reach areas.
• Safe Handling Packaging: Packaged in syringes for easy dispensing and safe handling.
