Abstract
Command-cure compositions especially for use in insulated window assemblies permit the composition to be rendered adhesively bonding at a selected time interval after formation of the assembly to firmly bond opposed surfaces of the assembly; a particular adhesive in strip or tape form comprises an adhesive polymer composition which is transparent to curing radiation especially UV, and curable in the presence of the radiation; the curing is inhibited by oxygen; the composition is solvent free and cures to a mass resistant to water; surfaces of the adhesive exposed to oxygen remain tacky and uncured; the adhesive is especially useful in window structures in which adhesion of the tacky surface excludes the cure-inhibiting oxygen and the tacky surface can be cured by UV radiation passing through the window glass.
