1,2-双三甲氧基硅基乙烷

1,2-双三甲氧基硅基乙烷用途

属于新型的双硅烷，即在同一分子结构中有两个硅烷结构。它们一个分子上有6个烷氧基，是普通硅烷偶联剂的双倍。因此，BTMSE和BTSE能在无机材料表面形成更高的交联密度；同时该产品水解后所形成的硅醇比普通硅烷偶联剂所形成的硅醇相比酸性更强，因此能与金属、无机材料表面的羟基所形成更牢固的共价键，且不易水解。
1.胶粘剂、密封胶中的交联剂，提供湿气固化功能，并提高对基材的粘接力。
2.硅烷偶联剂BTMSE 和BTSE 属于新型的双硅烷，即在同一分子结构中有两个硅烷结构。它们一个分子上有6个烷氧基，是普通硅烷偶联剂的双倍。因此，BTMSE 和BTSE 能在无机材料表面形成更高的交联密度；同时该产品水解后所形成的硅醇比普通硅烷偶联剂所形成的硅醇相比酸性更强，因此能与金属、无机材料表面的羟基所形成更牢固的共价键，且不易水解。
3.环保型无磷、无重金属的表面处理液，替代传统的磷化、钝化工艺。
