A.Mark Stypczynski, manager of technical development at Macco Adhesives/ICI Paints in Strongsville, Ohio, responds: Rhino Ultra Glue (800/634-0015, www.liquidnails.com) is freeze/thaw-stable. While it will thicken at low temperatures, it won't separate or otherwise be adversely affected, and it'll return to its normal viscosity upon warming.

Still, adhesives shouldn't be stored in a freezing environment. Because these products' viscosities are considerably higher when they're cold, it's possible that an inadequately warmed-up adhesive won't completely wet one (or both) of the bonding surfaces, which could result in a failure at some point in the life of the assembly.
