| 20120040104 | METHODS FOR MAKING CURED SEALANTS BY ACTINIC RADIATION AND RELATED COMPOSITIONS - Disclosed are methods for making a cured sealant. The methods include depositing an uncured sealant composition on a substrate and exposing the uncured sealant composition to actinic radiation to provide a cured sealant. The uncured sealant composition includes a thiol-terminated polythioether and a polyene comprising a polyvinyl ether and/or a polyallyl compound. Related sealant compositions are also disclosed. | 02-16-2012 |
| 20120040103 | COMPOSITIONS COMPRISING THIOL-TERMINATED POLYMERS AND SULFUR-CONTAINING ETHYLENICALLY UNSATURATED SILANES AND RELATED CURED SEALANTS - Disclosed are compositions that include: a) a thiol-terminated polymer; and b) a sulfur-containing ethylenically unsaturated silane. Related products, such as sealants, that include polymers derived from such compositions, are also disclosed. | 02-16-2012 |
| 20120031905 | CONTAINER CAP AND SEAL ASSEMBLIES - A container cap and seal assembly comprises a container base, a cap and a seal engagable with the container base. The seal is held on the cap when the cap is initially installed on the base. When the cap is subsequently opened, the seal disengages from the cap and remains on the base. The seal may then be manually removed and re-installed on the base as desired. The container assembly may be used to contain pastes, liquids and other flowable materials. | 02-09-2012 |
| 20110092639 | Compositions 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. | 04-21-2011 |
| 20110077351 | THIOETHERS, 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. | 03-31-2011 |
| 20110009557 | ONE-PART MOISTURE CURABLE SEALANT AND METHOD OF MAKING THE SAME - One-part moisture curable sealant compositions and methods of making the same are provided. The composition includes a silane-terminated polythioether component and a catalyst. The silane-terminated polythioether component and catalyst are isolated from moisture to prevent curing. The composition is stable against curing at ambient temperature and under conditions substantially free of moisture. When the composition is applied to a substrate and exposed to moisture, the composition cures to form a sealant. A method of making a sealant composition includes reacting a mercapto-terminated polythioether with a compound having a silane group to form a silane-terminated polythioether. The silane-terminated polythioether is then combined with a catalyst and isolated from moisture to prevent curing. Lastly, the composition is applied to a substrate and exposed to moisture which allows the composition to cure to form a sealant. | 01-13-2011 |
| 20100184899 | THIOETHERS, 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. | 07-22-2010 |
