Description
Chem-Set UltraLok UL406 is a two-part structural adhesive built for demanding metal, composite, and plastic bonds where a single-part glue falls short. This listing covers 50 mL cartridges carried at reduced pricing because the stock is past the manufacturer’s original shelf-life date, a common situation with methacrylate chemistries that lose some working consistency over long storage. Each cartridge ships with one static mixer for automatic 4:1 proportioning at the nozzle.
Where This Structural Adhesive Is Used
UL406 bonds dissimilar substrates, aluminum to steel, composite panels to metal frames, and most rigid plastics to each other, without the heavy surface grinding or etching primers that some epoxies require. Shops use it for structural panel bonding, sign and display fabrication, cabinet and enclosure assembly, and repair work where a fast fixture time keeps a line moving. Because it runs through a 4:1 cartridge with an integral mixer, crews get consistent ratio control shot to shot instead of hand-mixing small batches from cans, which cuts waste on short runs.
Handling and Storage
Given the reduced shelf life on this lot, run a small test bond and check working time and cure before committing to a full production batch, especially on a job with tight cycle times. Surface prep still matters even with a tolerant acrylic chemistry: clean, degrease, and lightly abrade glossy or oily substrates for the best peel and shear numbers. Store unopened cartridges in a cool, dry location out of direct sun, and use the included mixer only once per cartridge to avoid cross-contaminating the resin and hardener streams.

Order this adhesive when a bonded joint needs to go up fast without a mechanical fastener, and pick up an extra mixer or two from our structural acrylic adhesives category in case a second cartridge is needed mid-job. For application technique and bond strength demonstrations across our acrylic and structural lines, see the Chemical Concepts YouTube channel.
