Properties
- Physical Form
- Product Properties
- Dynasylan® 6498 is excellent as an adhesion promoter,dispersion and hydrophobation agent in mineral filled compounds.
- In the presence of moisture, the ethoxy groups of Dynasylan® 6498 hydrolyse to produce ethanol and reactive silanol groups.
- These silanol groups react with the filler via siliconoxygen bridges.
- The vinyl functional groups of Dynasylan® 6498 react with the polymer phase in the presence of radicals: A major field of application for mineralfilled compounds is the cable industry. EPDM and EVA can be processed into highly filled cable compounds through the adhesion promoting and hydrophobising effect of Dynasylan® 6498.
