1-Butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (BMI.NTf2) is a hydrophobic ionic liquid with potential antibacterial properties for dental materials. This study aimed to (1) incorporate different mass fractions of BMI.NTf2 into adhesive and (2) assess its impact on physical chemical properties. Adhesive resins were prepared 1 (G1%), 2.5 (G2.5%), 5 wt.% (G5%) BMI.NTf2, control group (GCTRL) lacking the liquid. Evaluations included polymerization kinetics, degree conversion (DC), softening in solvent (ΔKHN%), ultimate tensile strength (UTS). Groups showed accelerated G5% achieving higher DC ΔKHN% compared GCTRL (p < 0.05). Lower concentrations (1% 2.5%) did not affect ΔKHN%, no significant differences found UTS across groups > Notably, increased without affecting other properties, indicating optimal rates handling characteristics. These results support development BMI.NTf2-based adhesives that may assist preventing secondary caries restorative dentistry.
