Dynasylan® AMEO is a bifunctional silane possessing a reactive primary amino group and hydrolyzable ethoxysilyl groups.
The dual nature of its reactivity allows Dynasylan® AMEO 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, crosslinker, and/or surface modifier.
Dynasylan® AMEO is a colorless to slightly yellowish low-viscosity liquid with an amine-like odor. It is soluble in alcohols, and aliphatic or aromatic hydrocarbons.
In addition Dynasylan® AMEO is completely and immediately soluble in water.
Typical Applications
Dynasylan® AMEO may be used as a constituent of aqueous sizes, neat, or added to a resin or polymer as a modifier.
Examples are:
Dynasylan® AMEO may react with a variety of inorganic substrates and modify their surfaces. 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 react with a variety of organic resins and polymers and form silane-functionalized materials. Examples of suitable organic resins and polymers are epoxy, phenolic, furanic and melaminic resins, polyurethanes, PA, PBT, PC, EVA, modified PP, PVB, PVAC, PVC, PS, 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.
Addition reactions with suitable monomeric or polymeric compounds (e.g. isocyanates, epoxides, etc.) are established and state of the art.
Examples are:
- glass fiber/glass fabric composites: as a finish or size constituent
- mineral fiber insulating materials and abrasives: as an additive to phenolic resin binders
- foundry resins: as an additive to phenolic, furanic and melaminic resins
- sealants and adhesives: as a primer or additive and for chemical modification
- mineral-filled polymers or HFFR cables: for pretreatment of fillers and pigments
- paints and coatings: as an additive and primer for improving adhesion to the substrate.
- as a primer for glass and metal surfaces.
