Patent application numberDescriptionPublished
20090012244COMPOSITIONS INCLUDING A POLYTHIOETHER - Compositions, such as aerospace sealant, coating, and/or potting compositions are disclosed. The compositions include a polythioether and, in at least some cases, can be sprayable and fuel resistant even when substantially free of volatile organic compounds.01-08-2009
20090270554THIOETHERS, METHODS FOR THEIR PREPARATION, AND COMPOSITIONS INCLUDING SUCH THIOETHERS - Disclosed are thioethers, methods for preparing such thioethers, and curable compositions, such as coating and sealant compositions, that include such thioethers. The thioethers can be the reaction product of (a) an alpha, omega dihalo organic compound, (b) a metal hydrosulfide, and (c) a metal hydroxide.10-29-2009
20090326167COMPOSITIONS AND METHODS OF MAKING COMPOSITIONS EXHIBITING FUEL RESISTANCE - Curable compositions comprising polythioether polymers and polybasic acid-based polyepoxies, and methods of using curable compositions comprising polythioether polymers and polybasic acid-based polyepoxies are disclosed. Cured, curable compositions exhibit enhanced corrosion resistance and adhesion upon exposure to fuels.12-31-2009
20100010133SEALANTS AND POTTING FORMULATIONS INCLUDING MERCAPTO-TERMINATED POLYMERS PRODUCED BY THE REACTION OF A POLYTHIOL AND POLYVINYL ETHER MONOMER - Sealant and potting formulations are provided which are prepared from components including ungelled mercapto-terminated polymer(s) prepared by reacting reactants comprising polyvinyl ether monomer(s) and polythiol material(s); curing agent(s) reactive with a mercapto group of the mercapto-terminated polymer; and additive(s) selected from the group consisting of fillers, adhesion promoters, plasticizers and catalysts.01-14-2010
20100036063DIMERCAPTAN TERMINATED POLYTHIOETHER POLYMERS AND METHODS FOR MAKING AND USING THE SAME - Dimercaptan terminated polythioether polymers are disclosed, as are methods for making and using the same.02-11-2010
20100048852High impact poly(urethane urea) polysulfides - The present invention relates to a sulfur-containing polyureaurethane and a method of preparing the polyureaurethane. The sulfur-containing polyureaurethane has a refractive index of at least 1.57, an Abbe number of at least 32 and a density of less than 1.3 grams/cm02-25-2010
