Silane Coupling Agent BTMSE, 1, 2-Bis(trimethoxysilyl)ethane (CAS No. 18406-41-2)

Silane Coupling Agent BTMSE, 1, 2-Bis(trimethoxysilyl)ethane (CAS No. 18406-41-2), is a new type ograno-functional silane which contains 2 silyl groups, this unique structure enable it to have a better adhension to dry/wet surfaces, stronger and weather resistance bond. BTMSE is a colorless to slightly yellowish low-viscosity liquid. It is soluble in alcohols, and aliphatic or aromatic hydrocarbons. It can be slightly soluble in water, but hydrolysis occurs. 1, 2-Bis(trimethoxysilyl)ethane (CAS No. 18406-41-2), Silane coupling agent BTMSE, 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 coatingBTMSE 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
