Dynasylan® OCTMO

Dynasylan® OCTMO is a monomeric medium­ chain alkyl functional silane. Dynasylan® OCTMO is a clear colorless liquid and soluble in common non­polar organic solvents (e.g. petroleum ether, toluene). However its low volatility and viscosity make Dynasylan® OCTMO an easy ­to ­handle additive. During the hydrolysis reaction between water and Dynasylan® OCTMO a certain amount of methanol (VOC) is released.

Applications
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.
Application 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
