Abstract

The invention relates to a thermoplastic pressure-sensitive adhesive composition. The thermoplastic pressure-sensitive adhesive composition according to the invention comprises as essential elements a styrene-isoprene-styrene elastomer, at least one tackifying resin selected from aliphatic hydrocarbon, C8-aromatic and terpenephenolic resins and a block copolymer with elastomeric and rigid segments selected from copolyetheresteramides and copolyetheresterurethanes. It further preferably comprises a tackifying naphthenic oil and fillers. The composition according to the invention is particularly useful for bonding decorative streeps, protective rubber trims, mirrors, etc to panel bodies of painted cars and is therefore resistant to heat and gasoline.
