ABSTRACT:
This disclosure relates to a new fastener means for use on bolts, screws, nuts, threaded surfaces and the like which includes an adhesive composition comprised of a solid particulate adhesive, such as a low molecular weight crystalline adhesive or a high molecular weight non-crystalline solid thermoset resin, and a curing agent. The adhesive composition also includes a film forming carrier such as latex in which said solid particulate adhesive is dispersed and which does not dissolve nor react with said adhesive, and a microencapsulated solvent dispersed in said film forming carrier which acts upon the solid particulate adhesive to effect a cure. The adhesive composition may be applied over oily surfaces such as phosphate and oil coated bolts, without destroying the corrosion resistant phosphate and oil coating, and still provides excellent fastening properties. A fastener coated with said adhesive composition may be installed and removed several times without losing retaining properties, and this is believed due to the fact that only a portion of the microencapsulated solvent is used each time.
