Surgi-Lock 2oc is the veterinary equivalent of Dermabond. Chemically it is exactly the same, but it is cheaper and comes in a reusable bottle.
One annoyance with Surgi-Lock 2oc for first aid kits is that a separate pipette is needed to apply the glue.
2-octyl-cyanoacrylate (Surgi-Lock 2oc and Dermabond) does not have as long of a shelf-life as n-butyl-cyanoacrylate (Vetbond). This may be one reason that Dermabond is kept sealed in a shatterable glass enclosure.
