Bostik 1100 FS Fast Set Polyurethane Sealant Adhesive, White 10.1 Oz

Description

Bostik 1100 FS is a white fast set polyurethane sealant and adhesive for bonding, beading, and sealing in transportation, HVAC, container, and general industrial work. The one-part formula cures with atmospheric moisture to form a tough flexible seal on wood, metal, FRP, and many plastics.

Bostik 1100 FS Benefits

• One-component cartridge keeps field and shop use simple with no mixing step.
• 70 minute tool and work life gives crews time to place and finish longer beads.
• 90 minute tack-free time supports faster handling than many conventional urethane sealants.
• Class 25 joint movement capability helps sealed joints handle normal expansion and movement.
• White 10.1 oz cartridge fits standard sealant guns and common maintenance carts.

This product is commonly chosen for vehicle bodies, panels, and enclosure work where the bead needs to seal weather and stay flexible after cure. Do not use it for glazing, high-plasticizer materials, or corrosion-sensitive plastics unless the manufacturer has approved the assembly.

Common Applications

• HVAC enclosure sealing and bead work.
• Truck trailer, horse trailer, RV, bus, and railcar construction.
• Container seams, access panels, and industrial body joints.
• Bonding or sealing wood, metal, FRP, and many plastic substrates.
