Description
Bisco’s Porcelain Etchant 4% Hydrofluoric Acid (HF) Gel is a high-performance dental material designed to enhance the bond strength between porcelain surfaces and resin cement. This gel, formulated with 4% buffered hydrofluoric acid, microscopically roughens feldspathic porcelain and glass ceramics, creating a larger surface area for bonding. By doing so, it significantly improves the mechanical retention between the porcelain and adhesive, resulting in a durable and long-lasting bond. The gel consistency ensures precise control and easy application, making it ideal for sensitive procedures. It is primarily used for etching porcelain restorations prior to cementation and for the repair of fractured porcelain restorations. The product mimics the effect of sandblasting but offers a more controlled and effective process. Safety is a priority when using hydrofluoric acid, and Bisco’s Porcelain Etchant is specially buffered to minimize risks when handled according to the instructions. Dentists should use proper protective equipment, such as gloves and goggles, to avoid direct contact with the acid. The product is easy to rinse and compatible with silane coupling agents, making it an essential tool for reliable and strong porcelain bonding in restorative dentistry.
