Abstract
A hotmelt adhesive composition includes at least one polyolefin polymer (P) which is solid at 25° C. and is preferably a thermoplastic poly-α-olefin and more preferably an atactic poly-α-olefin (APAO), at least one polyolefin resin (PH) which is liquid at 25° C. and is preferably based on polyisobutylene, and optionally at least one polyolefin wax (PW) which is preferably a maleic anhydride-grafted polyolefin wax and more preferably a maleic anhydride-grafted polypropylene or polyethylene wax. The hotmelt adhesive composition is notable not only for high intrinsic tack and effective adhesion to low-energy surfaces but also for advantageously high UV integrity.
