Application Characteristics
  • Dynasylan® HYDROSIL 2776 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 2776 can be simply diluted with distilled water.
  • The following advantages are obtained over conventional organofunctional silanes:
  • Increased product and processing reliability:
    • no liberation of flammable organic constituents
    • flash point > = 95°C
  • 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
