Silquest* A-2120 Silane

SUPERIOR ADHESION FOR DIVERSE BONDING APPLICATIONS

Silquest A-2120 silane is a diaminofunctional silane that may be considered for a wide variety of applications. It can enhance the quality of adhesion in a broad range of amino-reactive resins, including silicon, silyated polyurethane, two-part urethanes and two-part epoxies. It may also serve as a valuable additive in phenolic and epoxy molding compounds, as well as in latex coatings, adhesives and sealants. When used as an additive, it often can eliminate the need for any bonding primer.

More About Silquest* A-2120 Silane

Silquest A-2120 silane also helps promote excellent adhesion to inorganic substrates, such as metal and glass, and plastics, particularly when combined with SPUR+* prepolymer adhesives or sealants. In addition to inorganic and plastic surfaces, Silquest A-2120 silane also can improve adhesion to inorganic fillers or reinforcements for a variety of sealants. As a difunctional silane, it can provide as much as a 35% improvement in elongation and superior stability in waterborne systems over trifunctional amino silanes. With polyamino functionality, Silquest A-2120 silane helps provide a reliable reactive site for amino-reactive resins and offers good wetting of substrates.

It is an excellent candidate to consider for use in RTV silicones and hybrid silane-crosslinked sealants to strengthen adhesion to glass, steel, aluminum and concrete substrates. Silquest A-2120 silane can also enhance adhesion of polysulfide sealants to glass, aluminum and steel.
