Product Details

Weld Mount AT-8040 is a high-strength, 2-part adhesive, designed to bond metals in severe environments. Advanced adhesive formula bonds objects without sliding, even on vertical and overhead surfaces.

AT-8040 cures incredibly quickly: At room temperature, with little surface prep, it establishes a handling strength within 12 minutes and a functional cure within 45 minutes, creating a lasting bond with superior strength (2,500 lbs. strength in 40 minutes). This solvent-free and VOC-compliant adhesive works with most metals, plastics, and composite surfaces.

Purchase the AT-850 mixing tips separately for use with the AT-8040 cartridge. Mixing tips are available in packages of 10 or 50.

Note: Apply AT-8040 with the AT-300 Adhesive Dispensing Gun (sold separately). Also available in a 30 ml dual syringe.

  • Eliminates welding, drilling, tapping, grinding and finishing steps
  • Eliminates costly rework expenses resulting from inadvertent drilling through substrates
  • Eliminates blocking added during lamination in order to have a place to put screws

Adhesive seems to work as advertised
By trailerable trawler owner from Florida, Georgia, Ontario

Verified Purchase

Used Weld Mount adhesive to hang bins and racks on the ceiling of our boat with Weld Mount large headed threaded studs. When mixed, the adhesive has a consistency similar to toothpaste or smooth peanut butter so the threaded studs stick well where placed. Pot life allowed me to mix a batch then place 8 or so mounts at a time. This project is now about 10 months old and has survived through one winter outside of Atlanta well so couldn't ask for more.

Bottom Line Yes, I would recommend to a friend
