ADHESIVE OF EPOXY RESIN, DIENE COPOLYMER-MODIFIED EPOXY RESIN, PHENOLIC-TERMINATED ELASTOMERIC TOUGHENER AND POLYESTER SEGMENT POLYMER

摘要

The present invention relates to an epoxy adhesive composition comprising a) afirst epoxy resin, b) a second epoxy resin modified with a copolymer based ona 1,3-diene and a polar, ethylenically unsaturated comonomer, c) a toughenerand d) a polymer comprising a polyester segment, said polymer being at leastpartially crystalline at room temperature and having a softening temperaturein the range of 40~ to 125~C. The invention further relates to the use of suchan epoxy adhesive composition for bonding parts of a vehicle withoutprehardening of the epoxy adhesive composition and to a vehicle, parts ofwhich are bonded by the epoxy adhesive composition.
