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.
用于绝缘窗组件的指令治疗组合物,允许在组件形成后的选定时间间隔内使组合物在粘合的情况下固定粘合组件的相对表面;特别是带状或胶带形式的特定粘合剂包括一种粘合聚合物组合物,该组合物对固化辐射特别是紫外线透明,并在辐射的存在下可固化;固化被氧气抑制;该组合物不含溶剂,可固化为耐水的质量;暴露于氧气的粘合剂表面保持粘性和未固化状态;该粘合剂特别适用于窗结构,在该窗结构中,黏性表面的粘合可排除抑制固化的氧气,并且通过窗玻璃穿透的紫外线辐射可以固化黏性表面。
