Laminating adhesive
A laminating adhesive includes a polyol; an acid-modified polyol obtained by reaction of a hydrophobic polyol containing a hydrocarbon moiety having 12 to 80 carbon atoms in its molecule in an amount of 30 to 95% by weight or a derivative thereof with an aromatic polycarboxylic acid anhydride and ha...

Summary: | A laminating adhesive includes a polyol; an acid-modified polyol obtained by reaction of a hydrophobic polyol containing a hydrocarbon moiety having 12 to 80 carbon atoms in its molecule in an amount of 30 to 95% by weight or a derivative thereof with an aromatic polycarboxylic acid anhydride and having a carboxyl group at a molecular terminal thereof; an organic polyisocyanate compound; and a silane coupling agent.A laminating adhesive film is excellent even after high-temperature sterilization treatment in adhesion performance between a metal foil or a barrier film and a plastic film serving as an inner layer, and also in adhesion performance between a metal foil or a barrier film and a plastic film serving as an outer layer. |
