Reactivity
  • Dynasylan® HYDROSIL 2627 is a clear to slightly yellowish liquid.
  • The following advantages are obtained over solution conventional organofunctional silanes:
    • Increased product and processing reliability: no liberation of flammable organic constituents flash point > = 95°C
    • Process flexibility: processing possible at elevated temperatures and in the vicinity of ignition sources or static charge
    • Applicational advantage: in polymer systems based on water as the solvent
    • Environmental protection: hydrolysis does not result in liberation of volatile organic substances

Application Characteristics
  • Dynasylan® HYDROSIL 2627 is an organosilicon compound based on water as the solvent and contains no volatile organic constituents.
  • Applications:
    • Surface treatment of minerals
    • Glass fiber reinforcement
    • Priming of glass and metal
    • Surface modifier for organic materials
  • Additive for water-borne polymer systems Depending on the area of application a concentration of active compound of approx. 0.5-5% may be employed. As a consequence, Dynasylan® HYDROSIL 2627 can be simply diluted with distilled water.
