ADHESIVE FOR DOUBLE GLAZING UNITS

摘要

An improved two-part adhesive system particularly adaptable for preparing multi-pane glazing units and improved spacer frames for multi-pane glazing units. The system comprises an adhesive composition and a primer composition. The adhesive composition comprises per hundred parts by weight from about 5 to about 50 parts by weight of a block copolymer having two polystyrene end blocks linked to a substantially saturated polyolefin rubber mid-block, from about 5 to about 50 parts by weight of an aliphatic hydrocarbon resin having a melting point not less than 60.degree.C., from about 2 to about 40 parts by weight of a curable epoxy resin and a finely divided inorganic filler. The primer composition comprises a heat softenable polymeric composition and an amine curing agent for the epoxy resin in the adhesive composition.
