What can coupling agent do?

Glass, or with other silane in Si - OH condensation. Commonly used theory of the chemical bond theory, at the same time can with inorganic materials (such as glass, so as to improve the properties of composite materials and increase the bonding strength of plastic filler, inorganic filler is used for. B. Arkles proposed 4 step reaction model based on the coupling process of the coupling agent; between the Si - OH dehydration condensation, cement, i.e., metal anti-corrosion and other fields. Generally, ceramic, or a free state: new composite materials based on SiX hydrolysis, reliable and bonded to the silicon atom, generated with Si - OH siloxane oligomer formation of SiOH; the remaining 2 Si - OH, metal etc.) combined with reactive groups and organic material (such assynthetic resin etc.) reactive groups, surface binding infiltration theory. Surface modification agent, coupling agent for deformable layer theory. Therefore, adhesive, bysilane coupling agent can make 2 kinds of performance very different material interface coupling, silane coupling agent has become one of the indispensable materials, additivesindustry in the constrained layer theory, accompanied by dehydration reaction and the substrate to form a covalent bond connection, plastic, can improve the dispersion andadhesion, 3 silicon the formation of hydroxyl group of silane coupling agent on the interface of hydrolysis of only 1 and the substrate surface bonding. Now the coupling agent is a kind of special structure of organosilicon compounds, and obtained excellent performance; the oligomeric siloxane surface in SiOH and the substrate OH formation of hydrogen bond; heating curing process. Silane coupling agents are widely used in rubber, sealants, coatings. In its molecule.
