Dynasylan® BTSE is the only commercially available bipodal alkylsilane. It is used in numerous applications where its nature as an excellent crosslinking agent is crucial. Its use usually requires acid- or alkali-catalysed hydrolysis. Since all six ethoxy groups are able to participate in this reaction, Dynasylan® BTSE is regarded as hexafunctional. Hydrolysis leads to silanol groups which, in a subsequent condensation reaction, form very stable siloxane bonds (-Si-O-Si-). Condensation starts before hydrolysis is complete. During storage of these hydrolysates, condensation continues until a gel is formed.

Dynasylan® SIVO 112 resembles a hydro- and oleophobic additive for Dynasylan® SIVO 110, a novel water-borne, sol-gel binder system.

Dynasylan® SIVO 203 is a new multifunctional aminosilane adhesion promoter that can be used for a wide variety of applications. Dynasylan® SIVO 203 is mainly dedicated for use in adhesives and; sealants to improve the adhesion of hybrid products (e.g. silylated polyurethanes, MS Polymers), RTV-silicones, two-part polyurethanes and two-part epoxies to inorganic surfaces and some difficult plastic surfaces. In addition, Dynasylan® SIVO 203 can lead to fast sealant curing and high-crosslinked products and it imparts both additional flexibility and hydrophobicity.

Dynasylan® 1175 is a cationic polymeric aminofunctional silane possessing hydrolyzable inorganic methoxysilyl groups. The dual nature of its reactivity allows Dynasylan® 1175 to bind chemically to both inorganic materials (e.g. glass, metals, fillers) and organic polymers (e.g. thermosets, thermoplastics, elastomers), thus functioning as an adhesion promoter and as a surface modifier. Dynasylan® 1175 is a dark yellow to brown liquid. Dynasylan® 1175 contains 40% active ingredient and about 60% of methanol. Dynasylan® 1175 is miscible with water, with hydrolysis occurring.

Dynasylan® HYDROSIL 2627 is an aqueous oligomeric aminoalkyl-functional silane hydrolysate. It is a colorless to slightly yellowish aqueous solution with an amine-like odour, miscible with alcohols or water.

Dynasylan® 2201 EQ is a bifunctional organosilane possessing a reactive organic ureido group and a hydrolyzable inorganic triethoxysilyl group.

Dynasylan® F 8263 acts as a surface modifier on oxidic, carboxy- and hydroxyfunctional substrates (e.g. glass, ceramic). Dynasylan® F 8263 is a colorless liquid. It can be diluted in alcohols and various other organic solvents, e.g. n-hexane, xylol, acetone or ethyl acetate.

VPS SIVO 260 is a novel multifunctional siloxane adhesion promoter with aminofunctionalities that can be used for various applications. VPS SIVO 260 is mainly dedicated for use in adhesives and sealants to improve the adhesion of hybrid products (e.g. silylated polyurethanes, MS Polymers®) and RTV-silicones - especially to difficult to stick polycarbonate substrates. In addition, VPS SIVO 260 can lead to adequate adhesive cure and it imparts both additional flexibility and hydrophobicity.

Dynasylan® P is mostly used as crosslinker for silicones. Dynasylan® P is a special silicic acid ester. It is mainly used as crosslinker in the silicone industry. Dynasylan® P can be further used as precursor for inorganic binders and as basic ingredient in sol-gel formulations.

Dynasylan® 1122 is a secondary aminofunctional ethoxysilane possessing two symmetric silicone atoms. Dynasylan® 1122 acts as an adhesion promoter between inorganic materials (for example glass, metals and fillers) and organic polymers (thermosets, thermoplastics and elastomers), as a surface modifier and can be used for the chemical modification of substances. Dynasylan® 1122 is a colorless to yellow liquid with an amine- like odor which is, for example, soluble in alcohols, aliphatic or aromatic hydrocarbons.

Dynasylan® SIVO 250 is a methacrylfunctional silane that can be used as adhesion promoter, surface modifier, co-monomer for polymer synthesis and crosslinker. Dynasylan® SIVO 250 is a clear, colorless liquid. It is soluble in alcohols, and aliphatic or aromatic hydrocarbons.

Dynasylan® VTEO is a bifunctional organosilane possessing a reactive vinyl group and a hydrolyzable inorganic triethoxysilyl group. The dual nature of its reactvity allows Dynasylan® VTEO to bind chemically to both inorganic materials (e.g. glass, metals, fillers) and organic polymers (e.g. thermosets, thermoplastics, elastomers), thus functioning as a crosslinking agent, adhesion promoter and/or surface modifier. Dynasylan® VTEO is a colorless, low­viscosity liquid with a typical aromatic odor.

Protectosil® SC CONCENTRATE is suited for an easy to clean reatment of many mineral substrates.
