TWO-COMPONENT CURABLE SOLVENTLESS ADHESIVE |
摘要 |
<p>To provide a two-component curable solventless adhesive which enables a laminated composite film comprising a barrier layer and a plastic film laminated with each other to maintain excellent appearance and adhesive strength for a long period even after a sterilization treatment at high temperature, and to appropriately adjust a reaction between a base resin and a curing agent during a production of the laminated composite film, thereby to ensure excellent workability, the two-component curable solventless adhesive comprises a base resin and a curing agent, wherein the base resin contains a polyol having an acid group and a secondary or tertiary terminal hydroxyl group accounting for 30% or more of the entire terminal hydroxyl groups of the polyol, and the curing agent contains an isocyanate group-terminated urethane prepolymer containing at least an aralkyl polyisocyanate and/or a modified substance thereof as a raw polyisocyanate, and a content of a low molecular weight polyisocyanate having a molecular weight of 190 or less is 3% by weight or less.</p> |
