Uni-Etch w/BAC is a 32% phosphoric acid semi-gel etchant that is effective at quickly etching enamel and dentin. Uni-Etch w/BAC is polymer-thickened and effectively removes the smear layer, etches and demineralizes enamel and dentin. It is easily manipulated into small areas such as endodontically treated root canals and undercuts. This makes it more versatile than some thicker gel etchants for etching all restorative surfaces. Published research proves that BISCO etchants produce higher bond strengths to (wet or dry) dentin1 and enamel.

BISCO’s porcelain primers are silane coupling agents used to improve bonding between porcelain restorations and resin cement. It also protects porcelain restorations from contamination and increases mechanical and chemical bonding of resin to the porcelain.
