Material Notes:
3M Aerospace Sealant AC-215 Class B are two-part, polysulfide access door sealants for faying surfaces where easy separation of jointed surfaces is required. They are a highly thixotropic reddish past which can easily be applied with a spatula, putty knife or caulking gun. The cured 3M AC-215 Class B Sealants have low adhesion and form a tough, “rubbery” gasket that molds well to surface irregularities.Information provided by 3M
