Porcelain Etchant™-Bisco-USA

Del catálogo de Alex Dent

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. BISCO’s PORCELAIN ETCHANT is available in 2 concentrations: 4% or 9.5% (Hydrofluoric Acid Gel).
