Etch-35™ w/BAC-Bisco-USA

From Alex Dent's catalogue

37% Phosphoric Acid Etchant with Benzalkonium Chloride Etch-37 w/BAC is a 37% phosphoric acid semi-gel etchant that is effective at quickly etching enamel and dentin. Etch-37 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) dentin 1 and enamel. Rinses away cleanly and quickly leaving no residue to interfere with bonding
