Prime Dental Etching Gel — 37% Phosphoric Acid, Silica Free

Prime Dental Etching Gel is a stable, silica-free formulation based on 37% phosphoric acid, designed for use in composite restorations, indirect restorations, and orthodontic bracket bonding. Unlike conventional etchants, this gel is developed without silica — since residual silica particles are known to be detrimental to bonding quality. The formulation remains stable over storage and does not dry or thicken, ensuring consistent clinical performance every time.

Available in two consistencies: Soft Gel and Thick Liquid — giving clinicians flexibility based on their preferred technique.

Indications

• Composite restorations
• Adhesive cementation of inlays (composite and all-ceramic), crowns, bridges, veneers, adhesive bridges, and posts & cores
• Splints
• Bonding of orthodontic attachments (e.g. brackets)
• Pit and fissure sealing
