Abstract
An insulated glass unit comprising two panes of glass and a sealant strip disposed around the periphery of the two panes in order to form a sealed space. The sealant strip is an isobutylene copolymer grafted with an organo-silane and includes 15-50 weight percent tackifier. The sealant strip is self splicing and is preferably sufficiently compression resistant so that additional compression resistant inserts or reinforcements are unnecessary.
Claims5
An insulated unit comprising:
- a sealant strip having a top surface and a bottom surface, said strip being located under a top pane and over a bottom pane, the top pane being bonded to the top surface of the sealant strip, and the bottom pane being bonded to the bottom surface of the sealant strip, the sealant strip extending around a periphery of the top and bottom panes to thereby create a sealed space between the top pane and the bottom panes, said sealant strip comprising about 15 to about 50 weight percent tackifier and comprising an isobutylene copolymer grafted with an organo-silane.
