Because of its unique structure, Dynasylan® SIVO 408 exhibits superior hydrophobicity on substrates and forms chemical bonds to substrates. Use of Dynasylan® SIVO 408 silane results in:
- Dynasylan® SIVO 408 treated inorganic substrates (e.g. titanium dioxide, ATH, or MDH) show excellent compatibility and dispersion characteristics especially in non/low polar matrices (e.g. in polyolfines and others).
- Dynasylan® SIVO 408 forms covalent bonds to the substrate surfaces and will not migrate out of the final compound.
- The significant increased compatibility leads to a reduced viscosity of the compounds, thus higher filler loadings are possible.
Applications & Uses

- Product Applications
Dynasylan® SIVO 408 silane can be used as a surface modifier to generate hydrophobicity (e.g. on inorganic pigments, mineral fillers). The short-chain alkyl functionality results in unique compound properties when Dynasylan® SIVO 408 treated minerals or pigments are incorporated into polymers, e.g. polyethylene or polypropylene. Loading levels of 0.5 to 1.5 weight-% Dynasylan® SIVO 408 based on the weight of filler or pigment are typically recommended. Dynasylan® SIVO 408 is excellent as a dispersion and hydrophobation agent in mineral filled compounds. Dynasylan® SIVO 408 forms covalent bonds to the inorganic surfaces and will not migrate out of the final compound as it will happen to silicone oils used as surface modifiers. In the presence of moisture, the ethoxy groups of Dynasylan® SIVO 408 hydrolyse to produce ethanol and reactive silanol groups. These silanol groups react with the filler via silicon-oxygen bridges. Dynasylan® SIVO 408 can be used in many other applications such as filler and pigment coatings, dispersions etc. Typical property improvements obtained by using Dynasylan® SIVO 408 in filled polymers are:
- Improved filler dispersion
- Good processability
- Significantly reduced water-uptake
