초록

The present invention is directed to a deformable window strip used to separate and seal two panes of glass. More specifically, the deformable window strip of the present invention comprises a flow resistent polymeric matrix which substantially decreases the need for rheological modifiers.

A strip having adhesion and sealing properties when used as a separating means between substantially parallel glass panes as part of an insulated glass window system, said strip comprising: a desiccant; a deformable sealant material having top, bottom, outer and inner surfaces; a spacer having top and bottom surfaces embedded upon the inner or outer surface of the sealant or within the sealant, said spacer having compressive strength to resist forces placed upon the top and bottom surfaces of said sealant and said spacer being deformable when forces are placed upon the outer or inner surface of said sealant, said top and bottom surface of said sealant extending from about 0.005 to about 0.060 inches beyond said top and bottom surfaces of said spacer; said sealant material comprising an elastomeric-based semi-interpenetrating polymer network formed by mixing together an unfunctionalized polymer with a curable polymer and, subsequently, adding a curative to the mixture to effect crosslinking of the curable polymer, the unfunctionalized polymer being substantially uncrosslinked, said formed sealant material having a shear flow of less than 40 mils, according to CEN shear test procedure 3.4
