Dynasylan® AMMO
- CAS Number
- 13822-56-5
- Chemical Name
- (3- Aminopropyl) trimethoxysilane
- Chemical Family
- Organosilane
Dynasylan® AMMO is a bifunctional organosilane, presents a reactive primary amine and hydrolyzable inorganic methoxysilyl groups. Its dual reactivity enables chemical bonding to both inorganic materials (e.g., glass, metals, fillers) and organic polymers (e.g., thermosets, thermoplastics, elastomers). Functioning as an adhesion promoter and surface modifier, Dynasylan® AMMO is a clear, colorless liquid with an amine-like odor. It shows solubility in alcohols and aliphatic and aromatic hydrocarbons.

- Processing
Dynasylan® AMMO can be used as an approx. 0.5-10 wt.% solution in an organic solvent or as a constituent of an aqueous size.; It may also be used neat or can be added to the polymer as an additive.; Chemical modification can be achieved by reaction of Dynasylan® AMMO with suitable functional monomers or polymers, for example those containing isocyanate or epoxy groups.
- Reactivity
In the presence of water, the methoxy groups of Dynasylan® AMMO hydrolyze form reactive silanol groups which can bond to a variety of inorganic substrates.; The organophilic amino group of Dynasylan® AMMO can react with a suitable polymer.; Hydrolysis of Dynasylan® AMMO takes place autocatalytically.; The pH of the hydrolysate is about 10-11.; Examples of suitable inorganic substrates are glass, glass fibers, glass wool, mineral wool, silicic acid, quartz, sand, cristobalite, wollastonite and mica as well as aluminum hydroxide, kaolin, talc, other silicate fillers, metal oxides and metals.; Dynasylan® AMMO may be used with such polymers as epoxy, phenolic, furan and melamine resins, polyurethanes, PA, PBT, PC, EVA, modified PP, PVB, PVAC, PVC, acrylics and silicones.; Dynasylan® AMMO can undergo reactions with ketone or ester solvents.; The silanes or silanized substrates can react with carbon dioxide to form the corresponding carbonates or carbamates, respectively.; Product modifications are possible through addition reactions with suitable monomeric or polymeric compounds (for example isocyanates, epoxides).
