BA-98 is a non-skinning, nonhardening, permanently flexible gun grade compound to limit sound transmission, to seal painted and aluminized steel panels as manufactured on a roll forming machine and to act as a vapor barrier for polyethylene vapor barrier films, wood, metal and foam boards. By remaining both permanently adhesive and flexible to all substrates, it maintains an airtight seal.
