Silquest A-Link 15 silane may be used for use as an endcapper or crosslinker for isocyanate functional prepolymer systems. This product provides improved thermal and UV stability over previous secondary amino silane endcappers. Silquest A-Link 15 silane can also be utilized as an adhesion promoter in silicone, hybrid, urethane, and epoxy adhesives and sealants.

Key Features and Benefits

Secondary Amino Functionality

• Provides a controlled reaction with -NCO, -COOH, and epoxy functional materials,providing a moisture cure silane crosslink mechanism
• Secondary amino functionality avoids viscosity instability associated with use of primary amino silanes as prepolymer endcappers/crosslinkers.
• This alkylamino offers enhanced thermal stability versus arylamino silanes.

Trimethoxy Silane Functionality

• Provides fast hydrolysis in the presence of formulated or atmospheric moisture.
• Provides excellent wet adhesion to glass, metal and other inorganic substrates.
• Resulting bond offers excellent thermal, chemical and UV stable performance.
• Amine catalyzed crosslinker and adhesion promotion in silane functional systems (silicone, hybrid, SPUR+* prepolymer technology modified urethanes).
