Abstract: Advances in oligomeric siloxane coatings applied as reactive silanols have arisen in the past several years that offer opportunities to solve problems that could not be addressed with traditional coating materials and methods. Although this class of new coatings is normally cited only for their corrosion resistance, they also exhibit the unusual phenomenon of having electron deficient surfaces. The electron deficient surface is formed as the coating cures in that organic radical groups from the silanes used in the formulation are forced to the surface of the coating. The silica atoms in the silicon oxygen structure below retain electrons skewing the electron cloud downward creating an electron deficient or net positively charged surface. The resultant surface discourages light hydrogen bonding of contaminants, thereby reducing leakage paths, particularly on insulators.

Abstract: Coating composition, articles, and methods for applying reactive silanol coating compositions having electron deficient surfaces formed as the coating composition cures wherein organic radical groups from the silanes are forced to the surface of the coating. The silicon atoms in the interpenetrating silicon-oxygen structure below retain electrons skewing the electron cloud downward creating an electron deficient or net positively charged surface. The resultant surface exhibits self-sterilization without toxic biocide additives due to the electron deficient surface. The surface is also extremely tight and thereby absent nutrients for microorganisms, discouraging organic growth such as mold. This unique positively charged surface further exhibits both hydrophobic and oleophobic qualities providing ease of cleaning for maintenance, particularly for hospital beds, equipment, floors, walls, curtains, bathrooms, or all the surfaces inside and outside of an ambulance and the equipment contained therein.

Abstract: Coating compositions and methods for applying reactive silanol coating compositions having electron deficient surfaces when cured wherein organic radical groups from the silanes are forced to the surface of the coating. The interpenetrating silicon-oxygen structure below the surface skews the electron cloud downward creating a net positively charged surface which is hydrophobic and oleophobic to repel contaminants by discouraging light hydrogen bonding. The surface is also extremely tight and thereby absent nutrients for microorganisms, discourages organic growth. These unique qualities provide cleanliness solutions for automotive and marine applications, including substrates subjected to elevated temperatures typically destructive to organic coatings (paints).
