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
