SikaLastomer®-511 is a high solids, non-hardening, butyl rubber-based sealant designed for factory sealing the female lip of standing seam roof and wall panels, and concealed endlaps.  Its permanent surface tack allows factory caulked panels to be bonded in the field up to six (6) months after initial application.    It has excellent pumpability and gunnability at low temperatures, as well as clean  “cut-off” properties, eliminating stringing from application by extrusion.
