Abstract
Abstract There is provided a hot melt adhesive for bonding shaped articles and surface structures of ethylene-propylene terpolymer (EPDM) between one another, or with other materials, consisting 100 parts by weight of styrene-ethylene-butylene-styrene block copolymer rubber; 10-150 parts by weight phr (per hundred rubber) aliphatic hydrocarbon resins; 50-300 parts by weight phr (per hundred rubber) aromatic hydrocarbon resins; and up to 1,000 parts by weight phr (per hundred rubber) bitumin with a softening point, according to the Ring and Ball method (DIN test 52011), 37/44-54/59.
