There are two major functionalities inherent to the chemical architecture of Silquest A-Link 15 silane that can benefit prepolymer or adhesive formulations. Its secondary amino functionality can enable:

• Controlled reaction with –NCO, -COOH, and epoxy functional materials, resulting in a moisture-cure silane crosslink mechanism
• Elimination of viscosity instability that may develop when primary amino silanes are used as prepolymer endcappers/crosslinkers
• Enhanced thermal stability over arylamino silanes as an alkylamino.

Silquest A-Link 15 silane’s trimethoxy silane functionality can help formulators provide:

• Fast hydrolysis in the presence of formulated or ambient moisture
• Excellent wet adhesion to glass, metal and other inorganic substrates
• Excellent thermal-, chemical- and UV-stable bond performance
• Amine catalyzed crosslinker and adhesion promotion in silane functional systems

With its numerous features, Silquest A-Link 15 can help deliver substantial benefits to a spectrum of endcapper, crosslinker, and adhesion promoter applications.
