Abstract
A method to adhere thermoplastic elastomer blends comprising PA1 (a) at least one thermoplastic polyolefin, PA1 (b) at least one non-cured, partially cured or fully cured elastomer or blends thereof, PA1 (c) a functionalized polyolefin and PA1 (d) optionally additives, to a polyester substrate, said method comprising the steps of PA1 treating the substrate with a blocked di-isocyanate in aqueous dispersion, or subsequently or simultaneously treating the substrate with a blocked di-isocyanate and an epoxy resin in aqueous dispersion/emulsion, PA1 applying the thermoplastic elastomer blend to the treated substrate and bonding the thermoplastic elastomer blend to the surface of the substrate using heat and pressure. The invention further relates to shaped articles obtainable by said process.
