BOSTIK 1200

Bostik 1200 Acetoxy Cure Silicone Sealant is a one-component moisture-curing silicone designed for perimeter and joint sealing on non-porous construction surfaces. It develops adhesion to glass, glazed ceramic tile, and aluminum and cures to a flexible elastomer with 570% elongation and +/-25% joint movement capability under the documented test conditions. A 10-minute tool/work time supports placement and tooling, while the cured service-temperature range extends from -45 to 150 deg C. Applications include sealing around windows and doors, metal frames, skylights, and selected dissimilar-material joints within the supported substrate scope.

Key features

• 25% Joint Movement: Demonstrates +/-25% joint movement capability under the documented joint-movement test.
• 570% Cured Elongation: Provides 570% elongation at break after the documented 14-day cure condition.
• 10-Minute Tooling Window: A 10-minute tool/work time supports placement and finishing before skin formation.

Applications

Perimeter sealing around windows and doors; sealing metal frames, windows and skylights; selected dissimilar-material joints within the documented substrate scope.
