Application
1, 2-Bis(triethoxysilyl)ethane (CAS No. 16068-37-4), Silane coupling agent SCA-K02X, 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. SCA-K02X 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.
