Porcelain etch 9.5% Bisco

Buffered Hydrofluoric Acid Gel
BISCO’s PORCELAIN ETCHANT improves the adhesive bond between porcelain and cement by increasing the surface area of the porcelain to be bonded. The effect is similar to sandblasting but is more controlled and effective. PORCELAIN ETCHANT will microscopically roughen the feldspathic porcelain or glass surface.
