摘要： Laminates of polymeric films and solvent-based polyurethane adhesive formulations for preparing them are provided. The adhesive formulations include a hydroxyl-terminated polyester that forms crystalline polyester domains after reaction with an appropriate polyisocyanate, but prior to completion of cure. The result is an adhesive layer that substantially enhances the oxygen barrier properties of the adhesive and, therefore, of the laminate as a whole, while offering desirable convenience of application even at relatively low temperatures. The laminates may also exhibit desirable retention of barrier properties following flex-cracking.

摘要： Methods for forming a laminate structure comprising a two-component solventless polyurethane adhesive compositions are disclosed. The adhesive composition is formulated such that each component is applied independently to corresponding substrates prior to the substrates being brought together to form the laminate structure. The adhesive compositions are highly-reactive and can comprise amine-initiated polyols or catalysts providing for fast curing. The amine-initiated polyols comprise a functionality of from 2 to 12, a hydroxyl number of from 5 to 1,830, and a viscosity at 40 C of from 500 to 20,000 mPa-s. The catalyst can be bismuth catalysts, zinc catalysts, zirconium catalysts, tin catalysts, and aluminum catalysts. Still further, a laminate formed according to the methods is disclosed.
