Water and glue don’t always
Water and glue don’t always mix. Even the toughest glue struggles to hold its own when submerged.
Scientists at Johns Hopkins APL have developed a stronger, faster underwater adhesive solution. They found that inserting a catalyst (to make it hold quickly) and a crosslinker (to make the hold strong) to the glue’s original formula would strengthen it. The fix was to use a shell to house the catalyst and crosslinker inside a microcapsule, similar to an egg shell. When a small amount of force is applied, the shells then break, solidifying the glue immediately. The result is a rapidly curing underwater adhesive, effective on untreated aluminum surfaces and with a high bonding strength in 60 seconds.
