The Acid Gel 10% is a gel base of hydrofluoric acid at a concentration of 10%, being the most efficient used way to attack the surface or porcelain, allowing bigger and better retention of resin materials in feldspathic porcelain restorations, glass ceramics and orthodontic brackets attachment. Its adequate viscosity and the presence of dye allow a safe application, no flowing danger and better visualization of the region to be constrained. Porcelain surface conditioning for bonding in restoration processes, with feldspathic porcelain and glass ceramics, Excellent viscosity for handling, no flowing danger.
