Silane-borate compound (10.0% borate) has proved to be termiticide. Four silane-borate compounds (10.0~13.8% borate) were prepared as termiticide, and then their stability under water rich environments were investigated. It was measured by the methods of the curcumic acid color reaction and the colorimetric with carminic acid. Results of these methods demonstrated the ability of the compounds to protect themselves against water attacks. This ability is performed by silane having groups with water repellency and reactivity to a wood surface, resulting that these silane-borate compounds have much better stability against water attacks compared to the standard termiticide DOT (15.0%) (Na2B8O13・4H2O).
