Dynasylan® AMMO

Dynasylan® AMMO is a bifunctional organosilane possessing a reactive primary amine and hydrolyzable inorganic methoxysilyl groups. The dual nature of its reactivity allows Dynasylan® AMMO 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 and a surface modifier. Dynasylan® AMMO is a clear, colorless liquid having an amine­like odor which is soluble in alcohols and aliphatic and aromatic hydrocarbons.

Product Applications
  • Glass fiber/glass fabric composites: as a size ingredient or finish
  • Glass and metal primers
  • Foundry resins: as an additive to cold­curing phenolic and furan resins
  • Sealants and adhesives: as a primer or additive and for chemical modification
  • Mineral­filled composites: for pretreatment of fillers and pigments
  • Paints and coatings: as an additive and primer for improving adhesion to the substrate.
Processing Information

Dynasylan® AMMO can be used as an approx. 0.5­10 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.

Product Properties

Dynasylan® AMMO can also improve processing properties such as

  • Adhesion
  • Filler dispersion
  • Rheological behavior: reduction in viscosity, Newtonian behavior
  • Increased filler loading
Product 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 10­11.
  • 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).
