Reactivity Information
  • Because of its unique structure, Dynasylan® OCTEO exhibits superior hydrophobicity on substrates and forms weather­ and moisture ­resistant bonds to substrates as well.
  • Use of Dynasylan® OCTEO silane results in: compatibility improvements between pigments or inorganic fillers and organic polymers or solvents, allowing easy pigment (e.g. iron oxides or titanium dioxide) or mineral filler (e.g. ATH, MDH) dispersion
Application Information
  • Dynasylan® OCTEO silane can be used as a surface modifier to generate hydrophobicity on inorganic fillers and pigments, e.g. titandioxide.
  • The medium­chain alkyl functionality results in unique compound properties when Dynasylan® OCTEO treated minerals or pigments are incorporated into polymers, e.g. polyethylene or polypropylene.
  • Loading levels of 0.5 to 1.5wt.% Dynasylan® OCTEO based on the weight of filler or pigment are typically recommended.
