March 15, 2006 – nGimat has been awarded a two-year, $750,000 SBIR Phase II contract by the Department of Energy for the development of nanostructured superhydrophobic self-cleaning surfaces on glass utilizing its patented Combustion Chemical Vapor Deposition (CCVD) process. Self-cleaning surfaces are receiving attention for a wide variety of consumer, industrial, military, and aerospace applications, such as architectural glass for homes and commercial buildings, automotive glass, shower doors, solar panel surfaces, and microfluidic systems.
“We plan to build on our promising preliminary results during the Phase II effort by focusing on nanostructured surface performance, scale-up and manufacturing costs,” said Todd Polley, VP of nGimat. “nGimat has received inquiries from multiple potential customers, several of whom are in the process of evaluating nGimat’s self-cleaning surfaces for commercial glass products.”
Self-cleaning surfaces would effectively eliminate the need for washing, scrubbing and chemical polishing of windows, ceramics and other surfaces. In addition to a reduction in cleaning requirements, these superhydrophobic surfaces have other benefits, such as improved safety when driving in severe rain and snow, and improved efficiency for solar cells due to the coatings anti-reflective and self-cleaning properties.
“We believe that our coating technology will enable high performance surfaces on large substrates at costs that will speed market adoption,”said Dr. Polley.
March 2, 2006 – nGimat Co. announced today the recent issuances of a U.S. patent and a Canadian patent directed to thin films (i.e. films 10 microns thick and less), laminates of thin films, and methods of producing thin films. Thin films and thin film laminates produced in accordance with these patents have a wide variety of technical applications including corrosion-resistance, moisture barriers, gas barriers, and protective coatings for electronic and ceramic components.
U.S. Patent No. 6,939,576, entitled “Polymer Coatings”, is directed to methods of producing thin film polymer coatings from solutions or dispersions of polymeric resins. A fluid containing the polymer is applied as finely atomized droplets to a surface to form a fluid film. Concurrently, a flame is applied to the fluid film to drive off any water or solvent and to fuse and/or cure the polymer to form the thin film coating. The methods of this patent are suitable for applying a wide variety of polymers, both thermoplastic and thermoset. One important application of this technology is the coating of plastic beverage bottles to substantially enhance gas barrier properties. Thin films of uniform high quality are deposited in an environmentally friendly and cost efficient manner.
Canadian Patent No. 2,296,505, entitled “Corrosion-Resistant Multilayer Coatings”, is directed to unique laminates of inorganic thin films. These thin film laminates are used to provide a moisture barrier and corrosion-resistance to metal substrates. The thin films of the laminates are primarily a variety of metal oxides and metal phosphates. The deposition methods taught in this patent produce films that, while very thin, are extremely durable and well-bonded to the substrates. The thinness of the films results in protected substrates having dimensions substantially unaltered from their pre-coated states, and in many cases, appearance substantially unaltered. There are already two U.S. Patents (Nos. 6,214,473 and 6,416,870) in place that protect nGimat’s coatings and associated process technology.
With these new patents, nGimat has a portfolio of 36 U.S. patents, 47 non-U.S. patents and is prosecuting over 125 patent applications.
