  • Laminating composition and uses
    Patent number: 4279659
    Abstract: A composition useful in lamination, the process of applying this composition, and the resulting laminated structure. This composition comprises (1) a microcrystalline-type wax, for example melting from about 140.degree.-200.degree. F. (2) a resin, for example petroleum polymer resins, terpene polymer resins, rosin and rosin esters, having a molecular weight of about 800 to 2,000 and (3) atactic polypropylene. The composition comprises about 20-40% of atactic polypropylene; about 10-25% of polymer resin; the balance (30-70%) being microcrystalline wax. This composition is applied and the plys joined together at a temperature above about 225.degree. F. to yield a laminated structure having optimum properties, particularly excellent hot peeling strength.
    Type: Grant
    Filed: July 11, 1979
    Date of Patent: July 21, 1981
    Assignee: Petrolite Corporation
