Publication number: 20120152754Abstract: Aqueous compositions useful as pretreatments prior to painting and to reduce the formation of rust in the uncoated condition consist essentially of water, an organo-functional silane, a compound of a Group IV-B element, and optionally a polyvinyl alcohol, stabilizing agents, wetting agents, thickeners, and biocides, and have an alkaline pH>7. A process for treating a metal surface includes contacting the surface with such an aqueous composition. The compositions and processes were found to have further benefits in comparison to the zinc phosphate metal pretreatment thought to be the standard in the industry. Preferably, the pH of the compositions is alkaline, which has been found to improve the efficacy of a silane as a surface treatment to improve uniformity of paint adhesion. By operating in the alkaline pH range, it was found that flash rusting and/or blush rust were significantly reduced.Type: ApplicationFiled: December 15, 2010Publication date: June 21, 2012Applicant: BULK CHEMICALS, INC.Inventors: Ted M.

Patent number: 8183085Abstract: Method and systems provide growth of polymer structures at a high rate in a selective manner. In various embodiments, the method or system can expose the growth site to a polymer source and growing a polymer tube at a rate of at least 80 micrometer per hour at the growth site. The method or system can provide selectivity by providing a growth site on a substrate by patterning a metal, such as copper, that provides a seed site for the polymer. Non-selected sites can be coated with a polymer growth inhibitor, such as polyimide or silicon nitride.Type: GrantFiled: March 31, 2009Date of Patent: May 22, 2012Assignee: Micron Technology, Inc.Inventors: Eyal Bar-sadeh, Nuriel Amir, Alexander Ripp, Yakov Shor, Dror Horvitz
