Abstract
A fastener sealing material for application to fasteners is formulated from an acrylate present in a concentration of about 90 to about 97 percent by weight of the sealing material and a nanostructured material present in a concentration of about 3 to about 10 percent by weight of the sealing material. The sealant is applied to the fastener as a liquid and is cured using an ultraviolet or LED light source and without the use of heat.
Claims16
A fastener sealing material for application to fasteners, comprising:
- an acrylate present in a concentration of about 90 to about 97 percent by weight of the sealing material;
- and
- a nanostructured material present in a concentration of about 3 to about 10 percent by weight of the sealing material,
- wherein the sealant is applied to the fastener as a liquid and is cured using an ultraviolet or LED light source and without the use of heat.
A two-article system in which first and second articles of the two-article system are joined to one another by a fastener having a sealing material on an underside of a head of the fastener and the shank or threads adjacent an underside of the head, the sealing material forming a cone-like shape at a transition from the shank or threads to the underside of the head, the sealing material formulated from an acrylate present in a concentration of about 90 to about 97 percent by weight of the sealing material and a nanostructured material present in a concentration of about 3 to about 10 percent by weight of the sealing material, the sealing material cured using UV or LED light prior to joining the articles to one another, wherein a group of the fasteners, when tested in accordance with General Motors Worldwide procedure GMW14906 4.5.4.3, Pressurization Seal Test exhibited zero failures, and with a test pressure increased to 10 psig, the group of fasteners exhibited zero failures.
A two-article system in which first and second articles of the two-article system are joined to one another by a fastener having a sealing material on an underside of a head of the fastener and the shank or threads adjacent an underside of the head, the sealing material forming a cone-like shape at a transition from the shank or threads to the underside of the head, the sealing material formulated from an acrylate present in a concentration of about 90 to about 97 percent by weight of the sealing material and a nanostructured material present in a concentration of about 3 to about 10 percent by weight of the sealing material, the sealing material cured using UV or LED light prior to joining the articles to one another, wherein a group of the fasteners, when tested in accordance with General Motors Worldwide procedure GMW14906 4.5.4.1, Vacuum Seal Test exhibited zero failures, and with a vacuum increased to 5 psi, the group of fasteners exhibited zero failures.
