| 摘要 |
This invention relates to a preapplied adhesive coating which can be deposited onto parts (e.g., nuts and bolts, slip-fitted tubing, or flanges), and left for long periods of time prior to use. The preapplied adhesive coating is dry to the touch, yet when the parts are assembled, the composition will cure between the parts, sealing and bonding them. The composition is comprised of a polymerizable monomer, a binder system, an initiator, and an accelerator of polymerization. The binder system is comprised of a copolymer of an anhydride and a compound selected from the group consisting of arylenes, alkylenes, alkarylenes, aralkylenes, alkoxyalkylenes, alkoxyarylenes, aryloxyalkylenes, and aryloxyarylenes. This invention also concerns an article, particularly threaded fasteners and the like, which is coated with the preapplied adhesive coating. |
