  • Hot-melt pressure sensitive adhesive composition having improved rheological properties
    Patent number: 11034868
    Abstract: An adhesive compositions containing at least one first styrene-isoprene-styrene block copolymer having a diblock content of not less than 45%, at least one second styrene-isoprene-styrene block copolymer having a styrene content of not more than 30 wt.-%, at least one first tackifying resin having a softening point of equal to or higher than 100° C., and at least one second tackifying resin having a softening point of equal to or higher than 120° C. Further, a method for bonding substrates together using the adhesive composition.
    Type: Grant

  • Water-based primer composition for polycarbonate and polycarbonate blends
    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.
