Features & Benefits
- CASE Ingredients Features
- Product Highlights
- Bis-silyl functionality - generally affords greater bonding or adhesion promotion to inorganic substrates.
- Secondary amino functionality - can typically improve shelf stability in various resin systems.
- Methoxy silane ester versions Silquest A-1170 silane and Silquest Y-9627 silane generally offer fast reaction with moisture, which translates to rapid cure or adhesion build.
- Ethoxy silane ester version Silquest Y-11699 silane generally provides a controlled cure with a by-product of the coupling or crosslinking mechanisms that have a lower impact on the environment.
Applications & Uses
- Applications
- Compatible Polymers & Resins
- Recommeded Usage
- Amino bis-silanes such as Silquest A-1170, Silquest Y-9627 and Silquest Y-11699 silanes have been shown to be effective in reacting with epoxy, urethane, melamine, polyimide, phenolic and furan thermosetting resins as well as many thermoplastics, such as polyamides and polyesters.
- Durable water-resistant bonds are generally achieved when the silyl portion of these aminosilanes are condensed with an inorganic surface and are covalently bonded with the resin matrix of the composite, paint, adhesive or sealant.
- The bis-alkoxysilane structure of the Silquest A-1170, Silquest Y-9627 and Silquest Y-11699 silanes result in the addition of two silyl groups to a resin. This typically yields more durable wet adhesion and more efficient bonding per mole of added silane.
- The ethoxy ester groups, as on Silquest Y-11699 silane, generally provide slower reaction with moisture, giving longer shelf stability when exposed to incidental or atmospheric moisture on storage
- The Silquest A-1170 silane and Silquest Y-9627 silane, as the methoxy ester versions, generally offer a quick cure and or rapid adhesion build.
- The higher purity grade of Silquest A-1170 silane may be considered for applications which demand low color, and greater control of reaction stoichiometry.
