Sawdust Treatment by Silane Coupling Agents
The silane concentration was 2.0 wt % and 5.0 wt % of sawdust and it was
dissolved in ethanol. Wood sawdust fibres were dried prior to use by heating in oven at
80 °C for 24 h until the weight was constant with a moisture content about 3 %. They
were mixed in silane solution for 2 h at 25 °C and were then dried at room temperature
and heated at 80 °C for 24 h in order to promote the actual chemical coupling [4].
