  • Publication number: 20100273696
    Abstract: An environmentally safe formulation to prepare an effective and permanent protection layer on almost all surfaces. The formulation consists of a combination of different silicon organic compounds, namely [a] end standing mono-, di- or tris-amino-alkyl-alkoxysilanes and [b] mono-, di-, or tris-alkyl-amino-alkylsilanes, in a long-chained isoparaffinic solution. The silicon organic compounds starts to polymerize in the presence of oxygen (air) and/or water (humidity), and builds up a net structure that water molecules can penetrate through the cured protective layer. Depending on the types of the silicon organic compounds, the pore width of the net structure can be verified. It is also possible to remove this protection layer, by using a special water based mixture of hydrofluoric acid and an inert surfactant.
