Patent number: 8869579Abstract: A fastener suitable for use in airplane manufacture or repair that is coated with a pre-mixed moisture cure sealant. The sealant layer is coated with a frangible moisture barrier that will break apart when the fastener is installed, thus exposing the sealant to atmospheric moisture. Once exposed to moisture, the sealant will begin to cure. Preferred embodiments also provide a moisture indicator that provides a visual indication that the outer moisture resistant layer has been damaged.Type: GrantFiled: December 29, 2011Date of Patent: October 28, 2014Assignee: Systems & Materials Research CorporationInventors: Alan V.

Patent number: 6787592Abstract: Organoclays based on specific types of ester quats are found to be remarkably effective for use in preparing nanocomposites. These organoclays comprise the reaction product of a smectite clay and a quaternary ammonium compound (or “quat”) which comprises two esterified radicals hereinafter called a “diester quat”). The diester quat may be present in admixture with further quaternary ammonium compounds having esterified radicals, especially compounds having three esterified radicals (hereinafter “triester quats”); or compounds having a single esterified radical (hereinafter “monoester quats”). Where such a mixture of quats is used, the reaction is between the smectite clay and the quat mixture.Type: GrantFiled: October 21, 1999Date of Patent: September 7, 2004Assignee: Southern Clay Products, Inc.Inventors: Clois E. Powell, James F. Gadberry, Michael Hoey
