Dow Corning Z-6124 SILANE
Categories: Other Engineering Material; Additive/Filler for Polymer

Material Notes: Dow CorningĀ® Z-6124 Silane has the chemical formula: (CH3O)3Si and is designated phenyltrimethoxy silane. Dow Corning Z-6124 Silane is a chemical monomer that reacts with water to form a silanetriol and methanol. Following hydrolysis, reactive silanol groups are formed, which can condense with other silanol groups, i.e., those on the surface of siliceous fillers, to form siloxane linkages.

Stable condensation products are also formed with other oxides such as those of aluminum, zirconium, tin, titanium and nickel. Less stable bonds are formed with oxides of boron, iron and carbon. Alkali metal oxides and carbonate do not form stable bonds with Si-O. Sufficient water for hydrolysis may be available from atmospheric moisture, or on the substrate surface. In some cases, it may be necessary to add water to increase the degree of hydrolysis. The tendency toward self-condensation can be controlled by using fresh solutions, alcoholic solvents, dilution and careful selection of pH ranges. Silanetriols are most stable at pH 3-4, but condense rapidly at pH 7-9.
