WATER-BASED ADHESIVE COMPOSITIONS

摘要

FIELD: chemistry.;SUBSTANCE: present invention relates to water-based adhesive compositions. Described is a water-based adhesive composition containing: an acrylic copolymer-based acrylic dispersion; polyester with an end epoxy group embedded in an acrylic dispersion having a structure; ,;where R¹ - is: ; ,;where G - is: ; ,;where j is from 0 to 5, -R2- is a divalent organic group selected from one or more divalent aliphatic groups, one or more divalent aromatic hydrocarbon groups or mixture thereof, containing -R21- is a divalent alkyl group, and -R22- is a divalent alkyl group which contains 4 carbon atoms; and an aliphatic isocyanate dispersible in water. Method for gluing a first film with a second film and laminar structures are also described.;EFFECT: technical result is improved adhesion to metal structures, such as foil, and improved thermal and chemical resistance due to two-component acryl/polyurethane adhesive compositions on a water basis.;7 cl, 3 tbl
