HUGE DENTAL USA HF-Etchant Hydrofluoric Acid Etching Gel

HF‑Etchant is a precision 9% hydrofluoric acid gel specially formulated for pre-treatment of resin-bonded porcelain and glass ceramic restorations. Its flowable consistency, vivid red tint, and controlled action make it essential for enhancing micromechanical retention before bonding or cementation.

Primary Indications

• Ideal for conditioning the surfaces of feldspathic porcelain, leucite glass ceramics, lithium disilicate, zirconia-reinforced lithium silicate, fluorapatite, and other silica-based restorations.
  
  

• Designed for extraoral use only—not suitable for etching enamel or dentin surfaces.
  
  

• Creates a micro-roughened surface to promote deeper resin infiltration and stronger mechanical interlocking, enhancing overall bond durability.
  
  

Key Features & Advantages

• Optimized 9% HF Concentration: Offers efficient etching while maintaining controlled behavior and safety in handling.
  
  

• Excellent Rheology: Flowable yet stable—ensures accurate placement without unwanted spreading.
  
  

• High-Contrast Visibility: The bright red hue helps practitioners monitor exact gel coverage on ceramic surfaces for precise application.
  
  

• Effortless Rinse-Off: Easily removed post-etch, leaving a clear, frosted surface ready for bonding procedures.
  
  

Packaging & Shelf Life

• Supplied in a single 1.2 mL syringe, complete with 10 dispensing tips for convenience and hygiene.
  
  

• Stable shelf life of 2 years when stored under appropriate conditions.
  
  

Safety & Usage Notes

• Highly Toxic Material: Hydrofluoric acid is hazardous and must be handled with utmost care. Use only with recommended personal protective equipment, protective barriers, and in well-controlled environments.
  
  

• Extraoral Application Recommended: Best applied to restorations before they are positioned intraorally. Ensure thorough water rinsing and neutralization after use.
  
  

• Avoid Contact with Soft Tissues: Even low-concentration HF can cause severe tissue damage. Strict isolation protocols are essential during any intraoral repair.
