AC-215 Class A is a two-part, polysulfide access door sealant for faying surfaces where easy separation of sealed surfaces is required. It is a pourable liquid suitable for brush or roller application. The cured AC-215 sealant has low adhesion and forms a tough, "rubbery" gasket that molds well to surface irregularities.

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.

AC-615 Class A is a two-part, low adhesion, chromate containing, corrosion inhibiting polysulfide access door sealant for faying surfaces where easy separation of joined surfaces is required. The mixed compound is a flowable, reddish liquid, thixotropic, which can easily be applied with a spatula, brush, roller or extrusion gun. The cured AC-615 sealant has low adhesion and forms a tough, "rubbery" gasket that molds well to surface irregularities.
