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. Similarly, buildings and their contents, construction materials, and infrastructure can be made self-decontaminating and greatly simplify cleaning from potential bio-warfare agents.

Method of treating surfaces for self-sterilization and microbial growth resistance

Oligomeric silane coating compositions containing, for example, methyltrimethoxysilane, are used to coat new or used heat exchange apparatus, such as HVAC systems, to greatly improve the heat transfer efficiency and prevent or inhibit corrosion. These oligomeric coating compositions are able to fill microvoids in the heat exchange surfaces, and penetrate into the microcavities at the interface of swaged or force fit surfaces, such as fins and tubes. The oligomeric silane coating compositions are highly active and will form bonds not only with the metal and metal oxides of the heat transfer surfaces, but will also displace gasses or liquids at the heat transfer contact surfaces and form chemical and/or hydrogen bonds with the oxides and chemical impurities. By so doing, a parallel heat transfer pathway is formed. The applied coatings may be as thin as only a few millionths of an inch and will fill microcavities to a depth of up to about 2000 nanometers. The coated heat transfer surfaces are non-adherent to deposition of soils and microorganisms and, therefore, are easier to maintain and are environmentally safe for use to heat/cool inhabited structures.

Corrosion resistant coatings are provided by aqueous-alcoholic acidic dispersions of the partial condensate of monomethyl silanol (by hydrolysis of monomethyl alkoxysilane) alone or in admixture with minor amounts of other silanol, e.g., gamma-glycidyloxy silanol, phenyl silanol, etc, wherein the dispersions contain divalent metal cations, e.g., Ca.sup.+2, in place of all or most of colloidal silica used in prior formulations of this type. The coatings may be applied to boat hulls, including aluminum hulls and are effective in preventing corrosion from salt water for extended periods.

A chronograph uses a Doppler radar technique to determine the muzzle velocity of a bullet discharged from small arms such as pistols and rifles. A radar unit is placed in near proximity to the firearm to track the bullet while it is still relatively close to the muzzle. The radar unit is equipped with an antenna which is insulated from the sonic disturbance created by the firearm blast by sonic damping means formed exteriorly on the antenna. Measured spacing and orientation of the antenna with respect to the firearm diminishes the sensitivity of the antenna to the electromagnetic disturbance associated with the firearm blast. Doppler signal processing means are also disclosed.
