Abstract: Background: Silane monomers like 3-(Trimethoxysilyl) propyl methacrylate (3- TMSPMA) are commonly used in composites to promote bonding between a filler and the surrounding matrix in composite. Aims: This study aims to use a silane monomer in different concentration as a dilute to prepare photo-cured composite adhesive and evaluate the properties of the composite adhesive. Adding 0.1 wt.% graphene gives the best mechanical properties in a previous study; therefore, the same percentage was added in this study. Materials and methods: The silane monomer, 3- (Trimethoxysilyl) propyl methacrylate (3- TMSPMA), was added at different weight percentages to Bis-phenol A glycerolate dimethacrylate (Bis-GMA) -0.1 wt.% graphene, photocured, and nanoindentation mechanical properties determined. Results: of the tested concentrations, it was found that 40wt.% Bis-GMA GMA yielded the largest increase in hardness and indentation modulus while decreasing the viscosity. Tunable viscosity is a valuable characteristic of adhesive components designed to be applied in narrow spaces, such as dental cavities. While the mechanical properties which are represented in load- displacement curves indicate at the same concentration presented the lowest plastic deformation (high elastic deformation) with low viscosity.
