Dynasylan® AMEO-T

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.

Product Applications

Dynasylan® AMEO­T is an essential constituent in many areas of application.

Examples are:

  • Primers: for glass and metal
  • Mineral fiber insulating materials, abrasives: as an additive to phenolic resin binders
  • Foundry resins: as an additive to phenolic, furan and melamine resins
  • Sealants and adhesives: as a primer or additive
  • Mineral­filled polymers (composites) or HFFR cables: for pre­treatment of fillers and pigments or as an additive
  • Paints and coatings: as an additive and primer for improving adhesion to the substrate.

The most important effects which can be achieved using Dynasylan® AMEO­T are: improvement of product properties, such as

  • Flexural strength, tensile strength, impact strength and modulus of elasticity
  • Moisture and corrosion resistance
  • Electrical properties, for example dielectric constant, volume resistivity improvement in processing properties, such as
  • Adhesion
  • Filler dispersion
  • Rheological behaviour: reduction in viscosity, Newtonian behavior
  • Higher filler loading
Processing Information
  • Dynasylan® AMEO-T may be used as an approximately 0.5­10 percent solution as a constituent of aqueous sizes, neat, or added to the polymer as an additive.

Product Reactivity
  • In the presence of water, the ethoxy groups of Dynasylan® AMEO-T hydrolyze to produce ethanol and reactive silanol groups, which can bond to a variety of inorganic substrates.
  • The organophilic amino group can react with a suitable polymer.
  • The hydrolysis of Dynasylan® AMEO-T takes place autocatalytically.
  • Aqueous solutions of Dynasylan® AMEO-T might show a certain turbidity. In these cases the hydrolysis is preferably carried out at pH 3.
  • Examples of suitable inorganic substrates are glass, glass fibers, glass wool, mineral wool, silicic acid, quartz, sand, cristobalite, wollastonite and mica as well as aluminium hydroxide, kaolin, talc, other silicate fillers, metal oxides and metals.
  • Dynasylan® AMEO-T may be used with such polymers as phenolic, furan and melamine resins, polyurethanes, PA, PBT, PC, EVA, modified PP, PVB, PVAC, PVC, acrylates and silicone.
  • Dynasylan® AMEO-T can undergo reactions with ketone or ester solvents. The silane or silanized substrates can react with carbon dioxide to form the corresponding carbonates and/or carbamates.
