Application
1, *-Bis(triethoxysilyl)ethane (CAS No. *********4), Silane
coupling agent BTSE, has some application as below:
1. RTV silicone sealants: To enhance the adhension to the dry or
wet surfaces and could form a stronger and weather resistance
bond.
2. Metal surface treatment: The toxic properties of chromates have
caused an environmental demand on replacement of the chromium (VI)
compound coating processes (chromating). One of the suggested
methods is a silane coating. BTSE with bis-silyl functional has six
hydrolyzable groups and are believed to be more crosslinked than
triand tetra-functional analogs. The enhanced crosslinking leads to
better barrier properties in anticorrosion applications.
