Abstract: The present invention relates to a system for the production of a sealant composite made of a primary sealing material and a curable secondary sealing material, the use of the system for the production of insulating glass or solar modules, an edge seal for the production of double-pane or multi-pane insulating glass or solar modules comprising the sealant composite and an insulating glass unit comprising at least two glass panes and the edge seal.

Abstract: A multi-pane window unit is described which comprises a. a first glass pane (1) having an inner surface (1.1) with an edge region and an outer surface (1.2) with an edge region, b. a second glass pane (2) having an inner surface (2.1) with an edge region and an outer surface (2.2) with an edge region, c. a spacer composed of (c a) a hollow profile (3) which can be filled with moisture-absorbing material, and whose inner space for the moisture-absorbing material is defined at least by two side walls (5) and a rear wall (6), wherein the inner space has a connection to the gap between the panes, and wherein a first sealant (7) is arranged between the side walls (5) of the hollow profile and the inner surfaces of the first and second glass panes, or (c b) a spacer (8) made of a non-flowing polymeric material d.
