ABSTRACT 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 compo- sition 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, alkoxy- arylenes, aryloxyalkylenes, and aryloxyarylenes. This invention also concerns an article, particularly threaded fasteners and the like, which is coated with the pre- applied adhesive coating. BACKGROUND OF THE INVENTION The concept of preapplied adhesives has long been recog- nized as a desirable object and numerous attempts have been made to provide such adhesives. For example, attempts have been made to encapsulate two-part adhesives, such as epoxides, and to apply them to parts prior to assembly. While this has permitted pre-application of adhesives to parts, totally ac- ceptable results have not been achieved. The encapsulation process is quite cumbersome and the attachment of capsules presents certain inherent problems, such as risk of loss of the capsules from the surface during storage or shipment. Also, mistreatment prior to use can lead to loss of adhesive due to premature rupturing of the capsules.
