GX-792 is a bifunctional silane possessing a reactive amino groups and hydrolysable 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 or elastomers). It is used as adhesion promoter at organic/inorganic interfaces, for modification of surfaces (corrosion prevention, component of primers) or silicone-polymer or as crosslinker (moisture crosslinking of polymers).
The use of GX-792 as a coupling agent leads to in general to an improvement of mechanical and electrical product properties above all under exposure to heat and/or moisture.
GX-792 is a colorless to slightly yellowish liquid with an amine-like odor which is soluble in alcohols and aliphatic as well as aromatic hydrocarbons.

Reactivity
GX-792 is a bifunctional organic compound in which the silicon-functional methoxy-groups hydrolyze in the presence of water to form reactive silanols, which can be bonded to an inorganic substrate; the organophilic diamino group can interact with a suitable polymer.
The hydrolysis of GX-792 takes place auto- catalyticcally. The pH of the hydrolysate is about 10. For longer stability of the hydolysale a pH of 4 is recommended. Examples of particularly suitable inorganic substrates are glass or glass fibres. Examples of suitable polymers are PA, PBT, PC, EVA, modified PP, PVAC, PVC, acrylates and silicones.
GX-792 can undergo reactions with ketones or esters as solvents. The silane or silanized substrates can react with carbon dioxide to form the corresponding carbonates. Product modifications are possible through addition reactions with suitable monomeric or polymeric compounds (such as isocyanates, exposides).
Application and performance
GX-792 is an important ingredient in many applications.
Examples are:
glass fibre/glass fabric composites: as size constituent or finish
glass and metal primers
sealants and adhesives: as primer or additive
mineral-filled polymers (composites): for pre-treatment of fillers and pigments or as additive
paints and coatings: as additive and primer for improving adhesion to the substrate
The most important effects which can be achieved using GX-792 are:
improvement in product properties, such as
flexural strength, tensile strength, impact strength and modulus of elasticity
moisture and corrosion resistance
improvement in processing properties, such as
adhesion
