Description
Amino functional silane coupling agent and adhesion promoter. Secondary bis-silyl amine with two hydrolysable groups per molecule. Gives higher crosslink density and better hydrolytic stability than primary amino silanes, and is preferred in metal pretreatment and in epoxy systems where yellowing must be limited. Releases methanol on hydrolysis.
