A multi glass pane unit comprising two panes of glass separated by a spacer frame with peripheral portions of the panes bonded to the frame surface(s) by the cured residue of a sealant composition provided by combining two separate parts of the sealant composition and where one part comprises a tertiary amine and a polymeric composition having a softening point between about 50°C. to about 190°C. and the polymeric composition comprises a block copolymer having two polystyrene end blocks linked to a substantially saturated polyolefin rubber midblock, a heat reactive phenolic resin and a tackifying resin and where the other part comprises an epoxy resin, and a polymeric composition which is non-tacky at temperatures up to about 50°C. and can be applied as a hot melt at temperatures between about 150°C. to about 190°C. and the polymeric composition comprises a block copolymer having two polystyrene end blocks linked to a substantially saturated polyolefin rubber midblock, a tackifying resin and a liquid polybutene having a molecular weight of about 10,000 or less.
