  "description_excerpt": "This application continues from International Patent Application No. PCT/US2008/006295, filed on May 16, 2008, which claims the benefit of an earlier filing date from U.S. Provisional Application No. 60/939,526, filed May 22, 2007, the disclosures of each of which hereby being expressly incorporated herein by reference.\n\n1. Field of the Invention\n\nThe present invention relates to curable adhesive and sealant compositions in a dry-to-the-touch form. More particularly, the present invention relates to dry-to-the-touch adhesive and sealant compositions which are particularly useful in threadlocking and sealing applications and may include various product forms of the compositions including dry-to-the-touch tapes and gaskets.\n\n2. Brief Description of Related Technology\n\nIt is common practice in the use of threaded mechanical fasteners, such as nut/bolt assemblies, to apply to one or more of the threadable engagement surfaces thereof, an adhesive/sealant composition, termed a threadlocking composition, for the purpose of locking and/or sealing the constituent members of such fasteners when they are engaged in their final interlocked state.\n\nSuch threadlocking compositions significantly increased the torque required to break or turn the engaged threaded members. Conventional threadlocking compositions oftentimes include co-reactive adhesive systems. With this type of threadlocking composition, two or more components are mixed before applying the resulting composition to the threaded engagement surface(s) of the fastener on which the components in the threadlocking composition react to cure.",
