Composite thermoplastic laminate
A composite sheet material includes a cover sheet, a substrate and an adhesion promoting layer. The cover sheet has a cover sheet material. The substrate has a substrate material. The adhesion promoting layer is disposed between the cover sheet and the substrate. A first side of the adhesion promoting layer disposed towards the cover sheet has an affinity to bond with the cover sheet material. A second side of the adhesion promoting layer disposed towards the substrate has an affinity to bond with the substrate material.
Primer compositions for optical films
Articles and laminates include a substrate with a first polyester surface and a second polyester surface, a crosslinked polyurethane-based primer coated on at least the first polyester surface, and an optically clear heat activated adhesive adjacent to the crosslinked polyurethane-based primer. The articles and laminates are prepared by applying a polyurethane-based dispersion and a crosslinker on at least one polyester surface, drying the applied coating, heating while stretching the substrate and the coating to form a crosslinked primer layer on the stretched polyester surface, and applying an optically clear heat activated adhesive onto the crosslinked primer layer.
PACKAGING MATERIAL FOR MOLDING, EXTERIOR CASE FOR ELECTRICITY STORAGE DEVICE AND ELECTRICITY STORAGE DEVICE
Provided is a molding packaging material capable of sealing without causing sealing failure, significantly reducing cleaning frequency of a seal bar to improve productivity, and preventing occurrence of delamination. The molding packaging material includes a PBT terephthalate (PBT) layer 2, a heat fusible resin layer 3, and a metal foil layer 4 between the two layers. The PBT layer 2 and the metal foil layer 4 are bonded via an outer adhesive layer 5. The outer adhesive layer 5 is formed of a urethane adhesive cured film composed of a polyester polyol, a polyfunctional isocyanate compound, and polyhydric alcohol. The polyester polyol contains a dicarboxylic acid component, the dicarboxylic acid component includes an aromatic dicarboxylic acid. The dicarboxylic acid component contains an aromatic dicarboxylic acid. The content rate of the aromatic dicarboxylic acid in the dicarboxylic acid component is 40 mol % to 80 mol %. The Young's modulus of the cured film of the urethane adhesive is 70 MPa to 400 MPa. The PBT layer has tensile strength of 100 MPa to 300 MPa.
LAMINATING ADHESIVES BASED ON PRIMARY HYDROXYL-CONTAINING CURATIVES
A curative containing two or more primary hydroxyl groups per molecule and one or more moieties derived from a secondary hydroxyl-containing polyol such as polypropylene glycol is prepared in a multistage process wherein the secondary hydroxyl-containing polyol is end-capped with an excess of a reactant such as a polybasic acid and the resulting functionalized intermediate is then reacted with a polyol such as glycerin or diethylene glycol containing primary hydroxyl groups. Such curatives may be used in combination with isocyanate-functionalized polyurethane prepolymers to provide two component adhesives useful for laminating thin films and/or foils.
