Dynasylan® AMEO
- Chemical Family
- Organosilane
Dynasylan® AMEO is a bifunctional silane, encompassing a reactive primary amino group and hydrolyzable ethoxysilyl groups. Its dual reactivity enables Dynasylan® AMEO to establish chemical bonds with both inorganic materials (e.g., glass, metals, fillers) and organic polymers (such as thermosets, thermoplastics, elastomers). It serves as an adhesion promoter, crosslinker, and surface modifier.

- Processing
Dynasylan® AMEO may be used as a constituent of aqueous sizes neat, or added to the polymer as an additive.. In higher concentrations chemical modification can be achieved by reaction with suitable functional monomers or polymers, for example those containing epoxy groups.
- Reactivity
In the presence of water, the ethoxy groups of Dynasylan® AMEO hydrolyze and form reactive silanol (Si-OH) groups which can bond to a variety of inorganic substrates.; Upon hydrolysis ethanol is released. The organophilic amino group of Dynasylan® AMEO can react with a suitable polymer.; The hydrolysis of Dynasylan® AMEO takes place autocatalytically. Hydrolyzates could be stable for concentrations higher than 10% for > 1 year.; The pH of the aqueous solution is about 11.; Examples of suitable inorganic substrates are glass, glass fibers, glass wool, mineral wool, silicic acid, quartz, cristobalite, wollastonite, mica as well as aluminum trihydrate, magnesium dihydrate, kaolin, talc, other silicate fillers, metal oxides and metals.; Dynasylan® AMEO may be used with such polymers as epoxy, phenolic, furan and melamine resins, polyurethanes, PA, PBT, PC, EVA, modified PP, PVB, PVAC, PVC, PS, nitril Kautschuk, polyester, acrylates and silicones.; Dynasylan® AMEO can undergo reactions with ketone or ester solvents.; Silane or silanized substrates can react with carbon dioxide to form the corresponding carbonates and/or carbamates. Product modifications are possible through addition reactions with suitable monomeric or polymeric compounds (e.g. isocyanates, epoxides, etc.).
