Min. Purity



  • With proper solvent dilution, it can penetrate to the hard, porous inorganic substrate, so as to achieve long-term deep hydrophobic antifouling protection.

  • Surfaces should be free of standing water, surface dirt, dust, oils, and other contaminants.

  • SiSiB® PC9751 alkyl silanes should be diluted in solvents such as 3M HFE-7200, HFE-7100, Fluorinert FC-77, Solvay Solexis HT-110; or perfluoroalkanes, such as perfluorohexane, perfluoroheptane, perfluorooctane, etc.

  • Typical dilution levels is 0.1~2% SiSiB® PC9751 in solvent.

  • Formulated solution should be stored at low temperature, sealed and avoid moisture; and it should be used as soon as possible.

  • Methods of application include airless sprayer, roller and brush. When a brush or roller is used, repeated applications should be made until the surface remains moist for a few minutes. If an airless sprayer is used, application should continue until the substrate is thoroughly saturated. Sprayers should be fitted with solvent resistant hoses and gaskets.

  • Treated substrates are hydrophobic, antifouling and retain their original appearance.

  • After drying at room temperature, it should be cured at least 10 hours at room temperature; or be cured at least 30 minutes at 100~150° C.

  • A test application is necessary on each surface to be treated to ensure compatibility and the desired result.

Packing and Storage

  • SiSiB® PC9751 is supplied in 1Kg bottle, 5Kg and 25Kg pail.

  • In the unopened container SiSiB® PC9751 has a shelf life of one year.
