GX-540 is a bifunctional organosilane possessing a reactive primary amine and hydrolysable inorganic methoxysilyl groups. The dual nature of its reactivity allows it to bind chemically to both inorganic materials (e.g. glass, metals, fillers) and organic polymers (e.g. thermoplastics, thermosets, elastomers) thus functioning as an adhesion promoter and/or surface modifier.

Reactivity
In the presence of water, the methoxy groups of GX-540 hydrolyze form reactive silanol groups which can bond to a variety of inorganic substrates. The organophilic amino group of GX-540 can react with a suitable polymer.
The hydrolysis takes place autocatalytically and the pH of the Hydrolysate is about 11. Examples of suitable inorganic substrates are glass, glass fibers, glass wool, mineral wool,silicic,acid,,sand,cristobalite,wollastonite, mica and aluminum hydroxid, kaolin, talc, other silicate fillers, metal oxides and metals.
GX-540 may be used with such polymers as epoxy, phenolic, furan and melamine resins, polyurethanes, PA, PBT, PC, EVA, modified PP, PVB, PVAC, PVC, acrylics and silicones.
GX-540 can undergo reactions with ketone or ester solvents. Silane or silanized substrates can react with carbon dioxide to form the corresponding carbonates and/or carbamates, respectively.Product modifications are possible through addition reactions with suitable monomeric or polymeric compounds (e.g. isocyanates, epoxides).
