  • Patent number: 10767083
    Abstract: A hot-melt glue composition, including a) at least one atactic poly-?-olefin (APAO) that is solid at 25° C.; b) at least one hydrocarbon resin having a softening point of at least 80° C., measured in accordance with the ring-and-ball method according to DIN EN 1238; and c) at least one maleic-anhydride-grafted wax having a softening point of not more than 150° C., measured in accordance with the ring-and-ball method according to DIN EN 1238, which is a maleic-anhydride-grafted polypropylene wax or a maleic-anhydride-grafted polyethylene wax, wherein the proportion of the at least one maleic-anhydride-grafted wax in the hot-melt glue composition is at least 3 wt %. The hot-melt glue composition is characterized by a low reactivation temperature, together with high heat resistance and good adhesion to ABS and nonpolar polyolefin materials. The hot-melt glue composition is well suited for film lamination by vacuum deep-drawing lamination, in particular for applications in automobile construction.
    Type: Grant

  • Patent number: 10385159
    Abstract: A water-based primer composition is particularly suitable for the pre-treatment of polycarbonate substrates, and has a component K1 having an aqueous epoxy resin dispersion, an aqueous polyester-polyurethane dispersion and an aqueous polyacrylate dispersion, and optionally a water-miscible organic solvent, and a second component K2 containing a water-dispersible curing agent based on isocyanate. The primers provide a strong bonding of subsequently applied adhesives to polycarbonate substrates, and permit a processing with a significant reduction in VOC emissions and the prevention of the occurrence of stress-cracks.

  • Publication number: 20110250012
    Abstract: A method is disclosed for manufacturing a roadway structure. To provide a good bond between plastic film and a bitumen-based support layer, an adhesive layer is provided that includes at least one fibrous material layer and one thermoplastic that is solid at room temperature. This method can allow for a rapid and efficient formation of a roadway structure.
