Translucent seal cap
First Claim
1. A protected fastener construction comprising:
- q) a fastener;
r) a seal cap which defines an interior; and
s) a cured sealant;
wherein the seal cap is optically translucent,wherein the seal cap is positioned over the fastener such that at least a portion of the fastener resides in the interior of the seal cap;
wherein the interior of the seal cap additionally contains the cured sealant which binds the seal cap to the fastener; and
wherein the seal cap comprises polyurethane polymer, polythioether polymer, polysulfide polymer, THV polymer, fluorinated thermoset polymer, engineering thermoplastic, or PEEK polymer.

Abstract
The present disclosure provides methods and articles useful in sealing fasteners, including seal caps and in particular translucent or transparent seals or seal caps. In some embodiments, a seal cap which is optically translucent and optionally visibly transparent contains an uncured sealant, which is optionally optically translucent or visibly transparent, and is applied to a fastener. In some embodiments, the sealant is cured by application of actinic radiation to the sealant through the seal cap. In another aspect, a protected fastener construction is provided comprising: q) a fastener; r) a seal cap; and s) a cured sealant; wherein the sealant is optically translucent and optionally visibly transparent.
