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.

Substrate Recommendations

Recommended for : 

• Steel: cold rolled steel (CRS). abraded surface 0.3 –0.6% Mn / 0.08 – 0.13% C / 0.05% S / 0.04% P
• Aluminum: alloy (3105 H 24) 96.8 – 97.4% Al / 1.0– 1.5% Mn / 0.6% Si / 0.05 –0.2% Cu
• Copper
