  • Adhesives with improved die-cutting performance
    Publication number: 20040007322
    Abstract: Improved label adhesives are provided through the use of selected mixtures of styrenic di- and tri-block copolymers, which have a reduced elastic behavior under die cutting conditions.
    Type: Application

  • Ethylene copolymers for hot melt systems
    Patent number: 4613632
    Abstract: Ethylene-vinyl acetate copolymers having a melt index of 2,000 to 7,500 and containing from 10 to 22% vinyl acetate are useful in hot melt road marking compositions containing from 1 to 30% of the EVA copolymer; from 0 to 29% by weight of a binder resin; and from 0 to 5% by weight of a plasticizer, the balance of the composition typically comprising from 70 to 80% by weight of aggregates, made up of particulate materials such as sand and/or fillers and/or pigments such as calcium carbonate and titanium dioxide.
    Type: Grant

    Inventors: Giorgio Aliani, Jacques B. Lechat, Jozef A. F. Smits
  • Ethylene copolymers for hot melt systems
    Patent number: 4497941
    Abstract: Ethylene-vinyl acetate copolymers having a melt index of 700 to 10000 and containing from 11 to 40% vinyl acetate are useful in hot melt systems and particularly in formulating low viscosity hot melt adhesives, preferably in binary compositions with natural or synthetic resin tackifiers. The adhesives show long open times with short setting times, and excellent adhesive properties.The EVAs are prepared by a high pressure polymerization, preferably by using chain transfer agent such as isobutylene to achieve high melt indices.
