Dynasylan® OCTMO is a monomeric medium-chain alkylfunctional silane.
Dynasylan® OCTMO is a clear colourless liquid and soluble in common non-polar 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.
Typical Applications
Dynasylan® OCTMO silane can be used as a surface modifier to generate hydrophobicity on inorganic fillers and pigments. The medium-chain alkyl functionality results in unique compound properties when Dynasylan® OCTMO treated minerals or pigments are incorporated into polymers, e.g. polyethylene or polypropylene. Loading levels of 0.5 to 1.5wt.% Dynasylan® OCTMO based on the weight of filler or pigment are typically recommended.
Benefits at a glance
Because of its unique structure, Dynasylan® OCTMO exhibits hydrophobicity on substrates and forms weather- and moisture-resistant bonds to substrates as well. Use of Dynasylan® OCTMO 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.
