Spacer having improved adhesion
A spacer (I) for insulating glass units, comprising at least: - a polymeric hollow section (1) comprising a first side wall (2.1), a second side wall (2.2) disposed parallel thereto, and a glazing interior wall (3) which connects the side walls (2.1, 2.2) to each other; - an outer wall (5) which is disposed substantially parallel to the glazing interior wall (3) and connects the side walls (2.1, 2.2) to each other; - a cavity (5) which is enclosed by the side walls (2.1, 2.2), the glazing interior wall (3) and the outer wall (5); and - a moisture barrier (30) on the first side wall (2.1), the outer wall (5), and on the second side wall (2.2) of the polymeric hollow article (1), the moisture barrier (30) comprising at least - a multi-layer system having a barrier function (33) and comprising at least one polymeric layer (35) and an inorganic barrier layer (34), - a metallic or ceramic external adhesive layer (31), the adhesive layer (31) having a thickness of less than 100 nm, and - a binding layer (32), which is disposed between the adhesive layer (31) and the multi-layer system (33) and comprises a polymer selected from the group comprising oriented polypropylene, oriented polyethylene terephthalate, biaxially-oriented polypropylene and biaxially-oriented polyethylene terephthalate, and the binding layer (32) directly adjoins the adhesive layer (31).
