Access Door Sealants

3M™ Aerospace Sealant AC-215 Class B - Low Adhesion

AC-215 Class B is a two-part, polysulfide access door sealant for faying surfaces where easy separation of sealed surfaces is required. It is a highly thixotropic reddish paste which can be applied with a spatula, putty knife or caulking gun. The cured AC-215 sealant has low adhesion and forms a tough, "rubbery" gasket that molds well to surface irregularities.
