Adhesion between the polymer matrix and fillers is an important factor influencing properties of obtained composites. One way to improve interactions at interface modify filler with coupling agents, e.g., silanes. The article presents effect modifying surface mineral a new type silane [triethoxy(ketoimino)silane] on mechanical polyester resin based Composites triethoxy(ketoimino)silane-modified...

This study evaluated: (1) the effect of different ceramics on light attenuation that could affect microhardness, measured as the Knoop Hardness Number (KHN), of a resin cement immediately and 24 hours after polymerization and (2) the effect of different activation modes (direct light-activation, light activation through ceramics and chemical activation) on the KHN of a resin cement. Resin cemen...

In this study, polyester composites reinforced with pistachio shells powder (P.) an averagediameter (150 – 200 μm) different weight ratios (0.5%, 1%, 1.5%, 2%, and 2.5%) wereprepared to the resin. The Shore D hardness, thermal conductivity (K), glass transitiontemperature (Tg) of samples were examined. results showed that hardnessincreases increase reinforcement ratio its maximum value is (87.5...
