37% ETCH
37% Phosphoric Acid Etchant

ETCH 37 is a 37% H3PO4 semi-gel, effective at quickly etching enamel and dentin. ETCH-37 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 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 specially formulated ETCHANTS contain benzalkonium chloride (BAC), an antimicrobial agent*s.

• Semi-gel formula rinses away cleanly and quickly leaving no residue to interfere with bonding
• Semi-gel formula offers superior microretentive surface characteristics
