Silquest A-1120 and A-2120 Silanes

Silquest A-1120, N (beta-aminoethyl) gamma-aminopropytrimethoxy-silane, and Silquest A-2120, N (beta-aminoethyl) gamma aminopropymethyldimethoxy-silane, are diaminofunctional silanes that may be used over a broad range of applications. They are used to promote the adhesion of amino-reactive resins such as silicone, silylated polyurethane, 2 part urethanes and 2 part epoxies to inorganic surfaces, and inorganic fillers or reinforcements.

The silanes find uses as:

• Adhesion promoters in polysulfide, polyvinyl chloride plastisol, silicone two-part urethanes and epoxy adhesives and sealants
• Additives in phenolic and epoxy molding compounds
• Additives to latex coatings, adhesives and sealants
• Adhesion promoters in one-part silylated urethane adhesives and sealants based on the company's OrganoSilicones Group SPUR Technology.

Key Benefits

• Polyamino Functionality
  • Provides reactive site for amino-reactive resins.
  • Good wetting of substrates.
• A-1120 Trifunctional Silane
  • Excellent adhesion to inorganic substrates such as metal, glass, etc.
  • Superior adhesion to plastics when employed in SPUR Technology-based adhesives or sealants.
• A-2120 Difunctional Silane
  • Excellent adhesion to inorganic substrates such as metal, glass, etc.
  • Superior adhesion to plastics when employed in SPUR Technology-based adhesives or sealants.
  • Provides as much as 35% improvement in elongation over Silquest A-1120 silanes.
  • Provides superior stability in waterborne systems over other trifunctional amino silanes.
