UNI-ETCH® w/BAC and ETCH-37™ w/BAC are 32% and 37% semi-gel phosphoric acid etchants with BAC (Benzalkonium Chloride), an antimicrobial agent. They are ideal for etching tooth structure prior to bonding and specifically formulated to be easily applied to larger surface areas and rinsed cleanly with no residue.
Intended for use on enamel, dentin, and as a cleaning agent for restorative substrates, UNI-ETCH® w/BAC and ETCH-37™ w/BAC will effectively remove the smear layer, etch and demineralize enamel and dentin, producing the necessary microretentive surface for successful bonding. The thixotropic etchant rinses away cleanly and quickly, leaving no residue.
UNI-ETCH® w/BAC and ETCH-37™ w/BAC is also available in 5g syringes packaged in a quantity of four.
