What it does

Aminosilanes (APTES / AMEO) — bifunctional coupling agents that bond inorganic substrates (glass, silica, mineral fillers) to organic polymers. The single most-used silane family in EU adhesive, sealant and composite formulation.

Typical applications

  • Adhesion promoter in PU and epoxy adhesives
  • Glass-fibre sizing for composites
  • Mineral-filler treatment (silica, wollastonite, kaolin)
  • Crosslinker in moisture-cure systems
