Dynasylan® PTEO an alkyltrialkoxysilane is important component in sol­gel systems. Dynasylan® PTEO is a colorless, low­viscosity liquid. Dynasylan® PTEO is regarded as trifunctional since all three alkoxy groups can hydrolyze. Additionally Dynasylan® PTEO contains a propyl group that adds a hydrophobic character to the 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® 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® 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® BDAC functions as a surface modifier in CASE ingredients and plastics and elastomers.

Protectosil® 266 F is a free flowing colorless to slightly yellow, frost resistant liquid based on a silane or siloxane. Protectosil® 266 F can be applied at full-strength or after dilution with suitable solvents, such as ethanol or white spirit.

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® 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® 4150 features chemical polarity yet remaining chemically not reactive. Such a non-coupling filler or pigment surface-modifier silane is used as a hydrophilic compatibilizer rather than as a covalent adhesion promoter. Due to its excellent wetting behaviour, Dynasylan® 4150 helps to control rheological properties and to reduce viscosity, allowing extremely high fillers loads in water and polar vehicles, permitting to achieve a powdery velvet touch sensation on the skin.

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® 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® 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® 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® 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.

Protectosil® 200N is an ultrapure, colorless, solvent free liquid water repellent based on Isobutylalkoxysilane, intended for the external waterproofing of mineral building materials. The ultrapure material is quaranteed to not leave a residue on non porcus substrates, such as glass or aluminum window framing. Protectosil® 200N chemically bonds with silaceous materials to form a permanent attachment of the water repellent molecule. Creates a deep hydrophobic layer which prevents water and waterborne contaminants from entering the substrate and causing premature detioration. Protectosil® 200N may be used as a concentrate or it can be diluted to manufacture other products and formulations.

Si 266™ is a silane used in rubber manufacturing as a base chemical for rubber products.
