Different concentrations (wt.%) of ZnCl<jats:sub>2<\/jats:sub> were added to a model etch-and-rinse adhesive system consisting of BISGMA, HEMA, UDMA, GDMA, water, and ethanol: Zn0 (0%-control group); Zn2 (2%); Zn3.5 (3.5%); and Zn5 (5%). Adper Single Bond 2 (SB) was used as commercial reference. The samples were light cured for 20s using a quartz-tungsten-halogen unit (650\u2009mW\/cm<jats:sup>2<\/jats:sup>). DC% (<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M1\"><mml:mi>n<\/mml:mi><mml:mo>=<\/mml:mo><mml:mn fontstyle=\"italic\">5<\/mml:mn><\/mml:math>) was measured using FT-IR spectroscopy, and WS and SO (<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M2\"><mml:mi>n<\/mml:mi><mml:mo>=<\/mml:mo><mml:mn fontstyle=\"italic\">5<\/mml:mn><\/mml:math>) were calculated based on ISO4049. Microtensile bond strength (<jats:italic>\u03bc<\/jats:italic>TBS) and nanoleakage (NL) were measured after 24\u2009h and 12 months of water storage (<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M3\"><mml:mi>n<\/mml:mi><mml:mo>=<\/mml:mo><mml:mn fontstyle=\"italic\">10<\/mml:mn><\/mml:math>). Data were analyzed using ANOVA and Tukey\u2019s HSD test (5%). Zn5 presented the lowest DC% and the highest WS and SO (<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M4\"><mml:mi>p<\/mml:mi><mml:mo>&lt;<\/mml:mo><mml:mn fontstyle=\"italic\">0.05<\/mml:mn><\/mml:math>). Zn0 and Zn2 presented statistically similar DC%, WS, SO, and immediate <jats:italic>\u03bc<\/jats:italic>TBS. All adhesives containing ZnCl<jats:sub>2<\/jats:sub> maintained a <jats:italic>\u03bc<\/jats:italic>TBS stability after 12 months, but only Zn2 and Zn3.5 did not suffer an increase in NL. SB presented the highest immediate <jats:italic>\u03bc<\/jats:italic>TBS but the greatest reduction after 12 months (<mml:math xmlns:mml=\"http:\/\/www.w3.org\/1998\/Math\/MathML\" id=\"M5\"><mml:mi>p<\/mml:mi><mml:mo>&lt;<\/mml:mo><mml:mn fontstyle=\"italic\">0.05<\/mml:mn><\/mml:math>). The addition of 2 wt.% of ZnCl<jats:sub>2<\/jats:sub> in adhesive formulations seems to be a promising way to improve the resin-dentin bonding stability. Higher concentrations than 2 wt.% could impair some physicochemical
