Description

BA-98 is a non-skinning, non-hardening, permanently flexible gun-grade compound to limit sound transmission, to seal painted and aluminized steel panels as manufactured on a roll forming machine, and acts 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.

Key Features

• Excellent adhesion to multiple substrates including clean concrete, gypsum, metal, glass, plastic, and wood surfaces without primer.
• Excellent gunnability, even at low temperatures.
• Wide service temperature range. Remains flexible at extremely low temperatures (-40°F).
• Long-term moisture barrier providing water resistance even under immersion conditions.
• Non-skinning, non-hardening, non-staining, and non-bleeding.
• Maintains Sound Transmission Class (STC) values in rated wall systems.
• Permanently adhesive and flexible to all substrates.
• Does not require cleaning, pretreatment
