  • Patent number: 10544295
    Abstract: The invention relates to a nontacky film-forming polymer composition (cover material), and tacky hot melt adhesives in the form of pellets which are coated with the polymer composition and producible by coextruding the hot melt adhesive and the cover material. The film-forming composition comprises 5 to 40% by weight of at least one Fischer-Tropsch wax having a melting point of >95° C. and 30 to 70% by weight of at least one metallocene-catalyzed polyolefin having a softening point of >95° C. and a melt flow index (MFI) (230° C., 2.16 kg) of ?1000 and ?300 g/10 minutes. The invention further relates to suitable uses for such hot melt adhesives, methods for their use, and products containing these adhesives.
    Type: Grant

  • Publication number: 20140087166
    Abstract: The invention relates to a process to manufacture an adhesive layer in an easy to handle process, whereby the adhesive is applied in a molten state to a substrate in an amount to form a layer of 150 to 5000 ?m and the adhesive is cured by UV-radiation whereby the adhesive comprises a polyurethane bearing at least one unsaturated curable group in the chain and the radiation source is preferably an UV-LED.
