Dynasylan® PTMO an alkyltrialkoxysilane is important component in sol­gel systems. Dynasylan® PTMO is a colorless, low­viscosity liquid. Dynasylan® PTMO is regarded as trifunctional since all three alkoxy groups can hydrolyze. Dynasylan® PTMO also contains a propyl group that adds hydrophobic character to sol­gel coatings. Hydrolysis leads to silanol groups which, in a subsequent condensation reaction, form very stable siloxane bonds (­Si­O­Si­). Condensation occurs parallel to hydrolysis once a certain amount of silanol groups have been formed. The absolute and relative rates of hydrolysis and condensation depend on a number of factors. The most important factors include pH, concentration, solvent, temperature and the catalyst.

Dynasylan® 6598 is an oligomeric siloxane containing vinyl, propyl and ethoxy groups. Dynasylan® 6598 is a further development of Dynasylan®VTMOEO, vinyl-tris(2-methoxy ethoxy)silane. Dynasylan® 6598 is a colorless, nearly odorless low-viscosity liquid. Dynasylan® 6598 is an excellent silane compatibiliser between inorganic fillers (e.g. kaolin, MDH, ATH) and organic polymers (EPDM, EVA, PE).

Dynasylan® MTMS an alkyltrialkoxysilane is an important component in sol­gel systems. Dynasylan® MTMS is a colorless, low­viscosity liquid. Dynasylan® MTMS is regarded as trifunctional since all three alkoxy groups are able to hydrolyze. Additionally Dynasylan® MTMS contains a methyl group that adds organic character to the products. Hydrolysis leads to silanol groups which, in a subsequent condensation reaction, form very stable siloxane bonds (­Si­O­Si­). Condensation occurs parallel to hydrolysis once a certain amount of silanol groups have been formed. The absolute and relative rates of hydrolysis and condensation depend on a number of factors. The most important factors include pH, concentration, solvent, temperature and the catalyst.

Dynasylan® AMEO-T is a blend of primary and secondary aminofunctional silanes. The blend contains more than 90 wt% of 3­ aminopropyltriethoxysilane. Aminofunctional silanes posses a reactive amino group and a hydrolyzable ethoxysilyl group. The dual nature of this reactivity allows Dynasylan® AMEO­T to bind chemically to both inorganic materials (e.g. glass, metals and fillers) and organic polymers (e.g. thermosets, thermoplastics, elastomers) thus functioning as an adhesion promoter, a surface modifier and a reactive reagent. Dynasylan® AMEO­T is a yellowish liquid with an amine­like odor. It is soluble in alcohols as well as aliphatic or aromatic hydrocarbons.

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.

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® F 8261 is a bifunctional silane possessing hydrolyzable inorganic ethoxysilyl groups and a fluoroalkyl chain. Dynasylan® F 8261 acts as a surface modifier on mostly hydroxyfunctional substrates (e.g. glass, ceramic). It can also be used as an adhesion promoter between inorganic materials and fluoropolymers (PTFE, fluorosilicones etc.). Dynasylan® F 8261 is a colorless and odorless liquid. It can be diluted to a proportion of about 25 wt.-% in ethanol and various other organic solvents, e.g. n-hexane, xylene, acetone or ethyl acetate.

Dynasylan® VPS 4721 is a bifunctional organosilane possessing a reactive organic epoxide and hydrolyzable inorganic methoxysilyl groups. The dual nature of its reactivity allows VPS 4721 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, crosslinking agent and/or surface modifier. Dynasylan® VPS 4721 is a colorless liquid. It is soluble in alcohols, ketones 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.

Dynasylan® 1505 is an amino-functional silane which acts as an adhesion promoter between inorganic materials (for example glass, metals and fillers) and organic polymers (thermosets, thermoplastics and elastomers) and as a surface modifier.

Dynasylan® 1189 is a bifunctional silane possessing a reactive secondary amine and hydrolyzable methoxysilyl groups. The dual nature of its reactivity allows Dynasylan® 1189 to bind chemically to both inorganic materials (e.g. glass, metals, fillers) and organic polymers (e.g. thermosets, thermoplastics and elastomers) thus functioning as an adhesion promoter or as a surface modifier and can be used for the chemical modification of substances. Dynasylan® 1189 is a colorless to slight yellowish liquid with a light amine­like odor which is, for example, soluble in alcohols, and aliphatic or aromatic hydrocarbons.

Dynasylan® SIVO 210 is an aminofunctional silane composition which 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 or as chemical modification of substances. Dynasylan® SIVO 210 is a colorless to yellowish liquid with an amine­like odor which is soluble in alcohols, aliphatic or aromatic hydrocarbons.
