Dynasylan® AMEO

• 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.).

Dynasylan® AMEO is an important additive for many applications.

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, furan and melamine resins
• sealants and adhesives: as a primer or additive and for chemical modification
• mineral-filled polymers (composites) 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

The most important effects which can be achieved through the use of Dynasylan® AMEO are:

• improved product properties, such as
  • improved mechanical properties, for example flexural strength, tensile strength, impact strength and modulus of elasticity
  • improved moisture and corrosion resistance
  • improved electrical properties, for example dielectric constant, volume resistivity
• Improved processing properties, such as
  • adhesion.
  • better filler dispersion.
  • rheological behavior: reduction in viscosity, Newtonian behavior.
  • higher fillerloading.

• 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.
