Dynasylan OCTEO is a monomeric medium-chain alkylfunctional silane.
Dynasylan OCTEO 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 OCTEO an easy-to-handle additive. During the hydrolysis reaction between water and Dynasylan OCTEO a certain amount of ethanol (VOC) is released.
Dynasylan OCTEO silane can be used as a surface modifier to generate hydrophobicity on inorganic fillers and pigments, e.g. titandioxide.
