Is It Worth Stabilizing Butyl Sealants Against Metal Ions? Key Benefits and Consequences for Sealant Quality and Durability
Butyl sealants—used in construction, energy systems, HVAC, automotive, telecommunications, and industrial applications—are valued for their exceptional airtightness, flexibility, and aging resistance. However, in many applications they come into contact with metals or environments containing metal ions such as copper, steel, aluminum, zinc, or their alloys. Metal ions can strongly catalyze
