Dynasylan® F 8261 can be applied in a wide variety of commercially important applications: Examples include:
- Treatment of automotive glass ("wiperless windshield")
- Easy-to-clean, water-repellent, UV-resistant coating of
- float glass (constructive glazing)
- Additive for sol-gel systems
- Synthesis of fluorosilicones
- Coating of pigments (e.g. in cosmetics)
- CVD processes
- Easy-to-clean coating on ceramics
- Processing Information
- Surfaces must be absolutely clean and degreased before treatment!
- E.g. the glass surface can be ideally activated with cerium oxide.
- For example: Glass treatment (e.g. on automotive glass) The silane is typically diluted to about 1 wt.-% in a suitable solvent (e.g. isopropanol) after which 2-10 wt.-% of distilllled water and 0.2 wt.-% of hydrochloric acid (37%) are added.
- The solution is stirred for about 5 hours and should then be used within one day. Substrate treatment can be carried out by dipping, spraying, rinsing, painting or polishing. The obtained polysiloxane film is completely invisible and will not lead to any optical impairment on the substrate.
Properties
- Physical Form
- Soluble In
- Product Reactivity
- In the presence of water, the ethoxy groups of Dynasylan® F 8261 hydrolyze to produce ethanol and form reactive silanol groups which can bond to a variety of inorganic substrates. The fluoroalkyl functional group provides a low energy surface. Hydrophobic and oleophobic surface properties can also be achieved by treatment with commercial fluorocarbon surfactants and resins.
- Dynasylan® F 8261 has an distinct advantage: The formation of a Si-O-substrate bond and subsequent horizontal crosslinking, which takes place upon evaporation of the solvent. This process leads to the formation of 2- and 3-dimensional networks. Thus starting from very low concentrations Dynasylan® F 8261 is able to form chemically and mechanically stable coatings which exhibit a thickness of only a few nanometers. Suitable substrates include glass, silica, quartz powder, sand, sandstone, cristobalite, wollastonite, mica, kaolin, talc, and other silicate surfaces.
