Introduction

SiSiB® PC9762 is a bifunctional silane possessing hydrolysable inorganic alkoxysilyl groups and a fluoroalkyl chain.

In the presence of water, the alkoxy groups of SiSiB® PC9762 will hydrolyze, producing reactive silanol groups that can be combined with various inorganic substrates, forming Si-O-base bonds on the surface, and further forming two-dimensional and three-dimensional network structures. .

Fluoroalkyl functional groups provide a low-energy surface but extremely poor wettability, providing excellent hydrophobic and oleophobic surface properties.

Applications

SiSiB® PC9762 can be applied in a wide variety of commercially important applications include:

Treatment of automotive glass

Anti-soiling, water-repellent, UV-resistant coating of float glass

Additive for sol-gel coatings

Anti-graffiti and easy-to-clean coatings

Adhesion promoter for fluoropolymers (paints, coatings etc.)

Synthesis of fluorosilicones

Coating of pigments

CVD processes

Processing

Surfaces must be absolutely clean and degreased before treatment! The surface can be ideally activated with cerium oxide.

Primer treatment (e.g. automotive glass)

1. Dilute SiSiB® PC9762 silane to a concentration of about 1% (wt) with a suitable solvent (for example: iso-propanol),

2. Add 2-10% deionized water of pH 3 (adjusted with acetic acid or hydrochloric acid solution).

3. Stir the solution for about 5 hours and then it is ready to use, but must be used within one day.

The substrate can be treated by dipping, spraying, curtain coating, painting and polishing.The resulting polysiloxane film is completely invisible and does not cause any optical damage to the substrate.

Packing and Storage

SiSiB® PC9762 is supplied in net weight 1Kg bottle, 5Kg/25Kg pail.

In the unopened container SiSiB® PC9762 has a shelf life of one year.
