1,2-Bis(trimethoxysilyl)ethane.
Synonym: Hexamethoxydisilethylene
Chemical Structure
Introduction
SiSiB® PC6112 (BTMSE) and SiSiB® PC6122 (BTSE) are clear to straw bis-silanes. SiSiB® PC6112 and SiSiB® PC6122 both contain two silyl groups, this unique structure enable it to have better adhesion and weather resistance.

Applications
SiSiB® PC6112 can be used to improve the adhesion of RTV silicone sealants to dry or wet surface, and improve its weather resistance.
SiSiB® PC6112 can be used to formulate chromate-free, water-borne primers to protect metals from corrosion.
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 applied as a combination of non-functional and organofunctional silanes. The silane coating can reduce underfilm corrosion and to improve the adhesion of the paint systems even compared to chromate layers. As a bis-silyl functional silane, SiSiB® PC6122 has six hydrolyzable groups and are believed to be more crosslinked than tri- and tetra-functional analogs. The enhanced crosslinking leads to better barrier properties in anti-corrosion applications.
